QUINOPHTHALONE PIGMENT, COLORED PHOTOSENSITIVE COMPOSITION USING THE SAME, AND USE OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a quinophthalone pigment (A) satisfying both solvent solubility and fastness (heat resistance, light resistance, and solvent resistance), and a colored photosensitive composition using the quinophthalone pigment.SOLUTION: A quinophthalone pigment (A) is represented following formula Z-Qn. (In the formula: Z is an n-valent organic residue; n is an integer of 2-6; and n Qs are each independently a group represented by general formula (2) wherein R-Rare substituents).
