PURPOSE: A compound for dye is provided to enhance heat resistance. CONSTITUTION: A compound for dye is represented by chemical formula(1). In the chemical formula(1), L1 indicates a short-chain, -SO2- or -CO-. A1 and A2 indicate benzene rings which independently have with substituent, naphthalene rings with substituent or quinoline rings with substituent. The compound(1) is manufactured by reacting a compound indicated by a formula (X), a compound indicated by a formula (Y1) and a compound indicated by a formula (Y2) in an organic solvent. The organic solvent used in the reaction is N-methylpyrolidone, 1,3- dimethyl -2- imidazolidinone, sulfolane, N,N- dimethylformamide, N,N- dimethylacetamide or a mixed solvent thereof. The used amount of the organic solvent is 30-50 parts by weight based on 1 part by weight of the compound. The coloring composite includes the compound of the chemical formula(1).
