Abstract:
A pigment-dispersion photo-sensitive coating solution which comprises a binder resin, an organic-solvent and a main pigment, C.I. Pigment Red 254, dispersed in the solvent, wherein the combined area of peaks detected at a relative retention ratio in the range of 0.68 to 0.72 based on a retention time of dibutyl phthalate and peaks detected at a relative retention ratio in the range of 1.06 to 1.10 based on a retention time of dibutyl phthalate is not more than 50% of the total area of all peaks when the pigment is extracted by ethyl acetate and the extracts are analyzed by high-speed liquid chromatography using dibutyl phthalate as internal standard.
