[0046] Further, the acid anhydride-functionalized fused-ring aromatic compound derivative is at least one of the following compounds:

##STR00009## ##STR00010## ##STR00011## ##STR00012## ##STR00013## ##STR00014## ##STR00015##

[0050] Further, the o-diamine compound is at least one of the following compounds:

[0051] wherein, R.sub.1, R.sub.2, R.sub.3, and R.sub.4 each independently represents at least one of H, halogen, cyano group, nitro group, aldehyde group, carboxyl group, acid anhydride, amide, imide, ester group, alkyl group, alkoxy group, and mercapto group;

[0053] X is a five- or six-membered ring structure containing S, N, O, CO, SO, SO.sub.2 or C═C groups.

[0054] In this embodiment, the fused-ring aromatic pigment in the mixture of the fused-ring aromatic pigment and the polymer material is at least one of the following compounds:

##STR00017## ##STR00018##

[0055] It can be understood that the fused-ring aromatic pigment that can be generated in the application is not limited to the ones described above, and fused-ring aromatic pigments that can be obtained by reacting any acid anhydride-functionalized fused-ring aromatic compound derivatives with o-diamine compounds are all covered within the scope of the application, and they will not be enumerated here.

[0056] Further, the mass content of the fused-ring aromatic pigment in the mixture of the fused-ring aromatic pigment and the polymer material is 0.1% to 50%.

[0057] It can be understood that the molar ratio of the acid anhydride functional groups in the o-diamine compound and the acid anhydride-functionalized fused-ring aromatic compound derivative is controlled to be 1:(1 to 1.1) and the molar ratio of the catalyst to the acid anhydride-functionalized fused-ring aromatic compound derivative is controlled to be (0.1 to 10):1, so that the o-diamine compound and the acid anhydride-functionalized fused-ring aromatic compound derivative are basically completely reacted under the action of the catalyst, and the content of the o-diamine compound in the obtained mixture is lower than 10 ppm, thus reducing the toxicity and carcinogenicity of the product.

[0058] Further, the catalyst is at least one of a water scavenger (such as quicklime, activated alumina, calcium chloride, calcium sulfate, lithium chloride, sodium chloride, sodium sulfate, and more), a Lewis acid, a Lewis base (such as zinc chloride, zinc acetate, titanium chloride, alkylamines, and more) and a metal oxide (such as titanium oxide, zinc oxide, aluminum oxide, and more).

[0059] Further, the thermoplastic polymer material is at least one of polyolefin, polyaromatic substituted olefin, polyacrylate, polyhalogenated olefin, polyimide, polyester, polyoxymethylene, polylactic acid, acrylonitrile-butadiene-styrene copolymer (ABS resin), polybenzo Imidazole (PBI), polyetheretherketone (PEEK), polyetherimide (PEI), polyethersulfone (PES), polyphenylene Ether (PPO), polyphenylene Sulfide (PPS), polyvinylidene Fluoride (PVDF), polycarbonate (PC), and polyimide (PA).

[0060] Further, extruding is carried out in an extruder. The extruder can be a single-screw extruder or a twin-screw extruder.

[0061] Further, the extruding temperature is 120° C. to 330° C. in a feeding section, 150° C. to 360° C. in an extruding section, and 180° C. to 380° C. in a sample discharging section along a material advancing direction.

[0062] It can be understood that the temperature curve of the extruding reaction is adapted to the total length of the extruder. For example, for a twin-screw extruder with 10 sections, the temperature curve application area of the extruding reaction is shown in the following table:

TABLE-US-00001 Sample Sample feeding 1 2 3 4 5 6 7 8 9 10 discharging Temperature/ 160- 170- 180- 190- 190- 190- 190- 190- 190- 200- 200- ° C. 330 360 370 380 380 380 380 380 380 380 380

[0063] For a single-screw extruder with 10 sections, the temperature curve application area of the extruding reaction is shown in the following table:

TABLE-US-00002 Sample Sample feeding 1 2 3 4 5 6 7 8 9 10 discharging Temperature/ 160- 170- 180- 190- 190- 190- 190- 190- 190- 200- 200- ° C. 330 360 360 380 380 380 380 380 380 380 380

[0064] Certainly, the above temperature curve can also be applied to extruders with more or less sections, usually depending on the selected reactants for generating the fused-ring aromatic pigment and the thermoplastic polymer material.

[0065] For the preparation method of the above-mentioned mixture of a fused-ring aromatic pigment and a polymer material, according to intermiscibility, processing temperature and polarity, different thermoplastic polymer materials can be selected and mixed with reactants (an acid anhydride derivative, an o-diamine compound and a catalyst) for generating a fused-ring aromatic pigment; by adjusting the reaction molar ratio of the raw materials and the dosages of the raw materials in the whole reaction system, the mixture of the reactants and the polymer materials can be extruded or kneaded to obtain a mixture of the fused-ring aromatic pigment and the polymer material in one step. Compared with the pigment, the raw material reactants of the pigment have better dispersity in the polymer material so that the pigment can be directly generated and uniformly dispersed in the polymer material through extruding or kneading. Moreover, in the extruding or kneading process, no solvent is required and an o-diamine compound is also almost completely consumed, so the obtained mixture does not need to be separated and purified. Therefore, the generation of the “three waste” in traditional pigment synthesis processes is avoided, the process flow is greatly simplified, the energy consumption and labor required can be reduced, and production costs can also be lowered.

[0066] It will be appreciated that by selecting reactants used to form the different pigments, and based on the possible color of the product, non-primary colors can be formulated during the extruding or kneading process. For example, black color can be obtained using reactants that produce red, yellow, and blue pigments; and green color can be obtained using reactants that produce yellow and blue pigments. Compared with the traditional method of mixing different pigments, the color of the mixture obtained by the application is more uniform.

[0067] In addition, since the raw material reactants of the pigment have better dispersibility in the polymer material, the pigment of the application can be directly formed and uniformly dispersed in the thermoplastic polymer material by extruding or kneading. Compared with the method of generating a pigment first and then mixing the pigment and a thermoplastic polymer material, the preparation method of the application can produce a mixture having better intermiscibility.

[0068] Further, the above-mentioned mixture of the fused-ring aromatic pigment and the polymer material can be cooled, dried and diced to obtain a crude color masterbatch.

[0069] Further, in order to obtain a high-quality color masterbatch products, additives (such as flame retardants, fluorescent whitening agents, UV absorbers, antioxidants, lubricants, plasticizers, antibacterial agents and other fillers required for the polymer material) required for traditional color masterbatches are mixed with the above-mentioned crude color masterbatch, and then the mixture is extruded, cooled, dried and diced to obtain a color masterbatch product. Or selectively the above-mentioned additives are mixed with the raw materials of the mixture of the fused-ring aromatic pigment and the polymer material, and the resulting mixture is then extruded, cooled, dried and diced to obtain a color masterbatch product.

[0070] The color masterbatch product has a particle size of 200 μm to 0.5 cm.

[0071] A high-quality polymer pigment can be obtained by further grinding the above-mentioned crude color masterbatch or color masterbatch product.

[0072] The polymer pigment has a particle size of 0.01 μm to 100 μm.

[0073] The following are specific examples.

[0074] In order to better test the performance of the crude color masterbatch, the crude color masterbatch having a concentration of 1% is mixed with ABS, and the resulting mixture is then subjected to injection molding to obtain an opaque sheet. The reflection spectrum of the opaque sheet is tested.

Examples 1 to 6

[0075] ##STR00019##

[0076] Examples 1 to 6 are all implemented in the following way.

[0077] 0.5 kg of PMMA, Compound (1-1) (32 g, 119 mmol), Compound (1-2) (25 g, 231 mmol) and a catalyst were mixed and extruded on a single-screw extruder to react, and the reaction product was then cooled, dried and diced to obtain a crude color masterbatch containing Compound (1-3).

[0078] Examples 1 to 6 are basically the same except for the type and dosage of the catalyst, as shown in Table 1:

TABLE-US-00003 TABLE 1 Example Catalyst Color of product 1 — Orange 2 CaO 4 eq Yellow-orange 3 Znic acetate 0.08 eq Orange 4 Oxalic acid 6 eq, CaO 4 eq Orange-red 5 Oxalic acid 6 eq Yellow-orange 6 CaO 4 eq, Znic acetate 0.08 eq Yellow-orange

[0079] FIG. 1 illustrates the reflection spectrogram of a 1 mm thick plastic sheet obtained by mixing ABS with the crude color masterbatch prepared in Example 4 with a concentration of 1% and injection molding. As can be seen from FIG. 1, its absorption is mainly in the blue light region to the orange light region, which is similar to that of a mixture of Pigment Orange 43 and

[0080] Pigment Red 194.

[0088] With reference to FIG. 3, the figure illustrates the reflection spectrum of the crude color masterbatch (having a concentration of 1%) prepared in Example 9 mixed with ABS.

[0091] With reference to FIG. 4, the figure illustrates the reflection spectrum of the crude color masterbatch (having a concentration of 1%) prepared in Example 10 mixed with ABS.

[0093] 1 kg of PMMA, Compound (11-1) (10 g, 50 mmol), Compound (11-2) (5.4 g, 50 mmol) and a catalyst zinc acetate (3 g, 16 mmol) were mixed and extruded on a single-screw extruder to react, and the reaction product was then cooled, dried and diced to obtain a pink crude color masterbatch containing Compound (11-3).

[0098] With reference to FIG. 5, the figure illustrates the reflection spectrum of the crude color masterbatch ((having a concentration of 1%) prepared in Example 13 mixed with ABS.

[0104] With reference to FIG. 7, the figure illustrates the reflection spectrum of the crude color masterbatch (having a concentration of 1%) prepared in Example 15 mixed with ABS.

[0108] In order to test the effect of the extruding reaction, a 0.01 mg/mL solution of o-phenylenediamine and 1,8-diaminenaphthalene (the solvent was composed of water and acetonitrile at a volume ratio of 3:7) was used as a standard sample, and 5 mL of solution of each of the materials (about 10 mg) of Examples 8, 9 and 10 (the solvent was composed of water and acetonitrile at a volume ratio of 3:7) was taken. Within a test range, no 1,8-diaminenaphthalene was found in the materials of Examples 8 and 10, and no o-phenylenediamine was found in the material of Example 9. It shows that this method can obtain a safe crude color masterbatch with a conversion rate of 100%.

It should be noted that those of ordinary skill in the art may further make variations and improvements without departing from the conception of the invention, and these all fall within the protection scope of the invention. Therefore, the patent protection scope of the present disclosure should be subject to the appended claims.
