Disclosed are a mixture of a fused-ring aromatic pigment and a polymer material and its preparation method and downstream product. According to the method, different thermoplastic polymer materials can be selected and mixed with reactants 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 reactant and the polymer material 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.

An infrared cut-off filter including a cyanine dye including a tris(pentafluoroethyl) trifluorophosphate anion and a cation having a polymethine and a nitrogen-containing heterocycle located at each end of the polymethine, and an acrylic polymer having a unit structure of formula (1).

A polysiloxane-substituted quinacridone pigment is produced by a quinacridone pigment with an epoxy-terminated polysiloxane under conditions effective to cause the epoxy group on the polysiloxane to react with, and bond the polysiloxane to, the quinacridone pigment. The quinacridone pigment thus produced has the polysiloxane grouping bonded to one of the quinacridone nitrogen atoms via a hydrocarbon linking group, which bears a hydroxyl group on a carbon atom α or β to the quinacridone nitrogen atom. These quinacridone pigments are useful in electrophoretic displays.

A near infrared absorbing composition includes a near infrared absorber. The near infrared absorber contains at least one of Ingredient (A) and Ingredient (B). Ingredient (A) consists of a first compound having a first structure represented by General Formula (I), a second compound having a second structure represented by General Formula (II), and a copper ion. Ingredient (B) consists of a first copper complex in which the first compound is coordinated and a second copper complex in which the second compound is coordinated. In General Formula (I), R.sup.1 represents an alkyl group containing 1-20 carbons or an aryl group containing 6-20 carbons, and may further have a substituent. In General Formula (II), R.sup.2 represents an alkyl group containing 1-20 carbons or an aryl group containing 6-20 carbons, and may further have a substituent.
