    Description

    EXAMPLES

    [0276] In the case of molecularly inhomogeneous substances, the stated molecular weights are number-average values. The molecular weights or number-average molecular weights M.sub.n, in the event that titratable hydroxyl or amino groups are present, are determined by end group determination via the finding of the OH number or the amine number. In the case of compounds to which end group determination is not applicable, the number-average molecular weight is determined by means of gel permeation chromatography against a polystyrene standard.

    [0277] Unless stated otherwise, figures in parts are parts by weight and figures in percent are percent by weight.

    Solids Content

    [0278] The sample (2.00.1 g of test substance) is weighed into an aluminum dish that has been dried beforehand and dried in a drying cabinet at 150 C. for 10 minutes, cooled down in a desiccator, and then re-weighed. The residue corresponds to the solids content.

    NCO Number

    [0279] The free NCO content of the polyisocyanates being used and the course of reaction of the NCO additions is determined according to EN ISO 9369 by reaction with butylamine and subsequent titration of the excess of amine. These methods are also described in Saul Patai The Chemistry of Cyanates and their Thioderivates, Part 1, Chapter 5, 1977.

    OH Number

    [0280] The OH number is determined according to DIN ISO 4629 by acetylation with an excess of acetic anhydride. Subsequently, the excess acetic anhydride is hydrolyzed to acetic acid by addition of water and back-titrated with ethanolic KOH solution. The OH number indicates the amount of KOH in mg equivalent to the amount of acetic acid bound in the acetylation of 1 g of substance.

    Amine Number

    [0281] The amine number (AN) is understood to mean the amount of KOH in mg corresponding to the amine content of 1 g of substance. The amine number is determined according to DIN 16945 by potentiometric titration with 0.1 N perchloric acid in acetic acid.

    Application and Evaluation of the Pigmented Nitrocellulose Varnish NC1-B3 (blue)

    [0326] The pigmented nitrocellulose varnish NC1-B3 (blue) was bar-coated onto PE film (50 m) and dried at 22 C. for 24 h. Then the optical transparency and color intensity through the drawdowns onto PE film was assessed using grades 1 (excellent) to 5 (unacceptable). The colorimetric assessment of the drawdowns was conducted with a BYK-Gardner color guide D65/10 in the CIELab color space (L, a, b).

    [0328] It should be particularly emphasized here that smaller a values in terms of magnitude indicate better dispersion of the blue pigment, and negative b values that are larger in terms of magnitude point to a deeper blue impression. This trend is shown by inventive examples MA22, MA59 and MA47 compared to the prior art.

    Application and Evaluation of the Pigmented Baking Varnishes JC1-B1 to JC1-B3

    [0329] The pigmented baking varnishes JC1-B1 to JC1-B3 were bar-coated onto PE film (50 m), flashed off at 22 C. for 15 min and baked at 150 C. for 20 min. Subsequently, haze and gloss were measured with a BYK micro haze plus instrument at an angle of 20. In each case, low values for haze and high values for gloss are considered to be positive results. In addition, the optical transparency and color intensity through the drawdowns onto PE film was assessed using grades 1 (excellent) to 5 (unacceptable).

    Production of the Final Test Formulations Based on Dynapol LH 830

    [0348] The pigment concentrates PKR1, PKG1 and PKS1 were each formulated with the corresponding white base ASW1 using the same dispersing additive. The final test systems TSRW1 (PKR1+ASW1), TSGW1 (PKG1+ASW1) and TSSW1 (PKS1+ASW1) contain, for example, DISPERBYK-170 only as prior art dispersing additive. The same applies analogously to the other inventive examples in the table below.

    [0351] The final test systems are formulated by weighing white base and pigment concentrate in each case together into a sealable vessel. The mixture is homogenized in a Skandex shaker for ten minutes. Subsequently, the varnishes are applied to aluminum sheet by means of a spiral coating bar in a wet film layer thickness of 80 m. In a coil oven, the varnishes are baked at 320 C. for 33 seconds with peak metal temperature 232 C. A dry layer thickness of about 18 m is achieved.

    [0352] A rubout test is also conducted in order to determine the difference in shade (E) between rubbed and unrubbed surface within the rub. For this purpose, a portion of the final test systems that have been homogenized on the Skandex shaker are applied again to aluminum sheet by means of a spiral coating bar in a wet film layer thickness of 80 m. Subsequently, a portion of the varnish applied is rubbed (sheared) in horizontal direction in each case using a finger. Subsequently, the varnishes are baked in a coil oven at 320 C. for 33 seconds with peak metal temperature 232 C. After cooling, the difference in shade (E) between rubbed (sheared) and unrubbed surface is measured by means of colorimetry with a BYK spectro-guide sphere. A small difference in shade AE indicates that both pigments (white and the respective shade) in each case are equally stabilized and no floating is observed.
