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.
