The coloration resist constituent and the color - filter which use the dioxazine type pigment

摘要

PROBLEM TO BE SOLVED: To provide a color resist composition containing a dioxazine pigment showing preferable dispersibility compared to a conventional dioxazine pigment and to provide a color filter which uses the above color resist composition. SOLUTION: The color resist composition for a color filter contains a new dioxazine purple pigment expressed by general formula (1), a photosensitive resin and a solvent. In the formula, R represents formula (2), (3) or (4), X represents a C=O group, Y represents a NH group and the heterocycle included in R is a five- or six-membered ring. In general formula (1), the R part has an imino group (HN) as a bond constituting a ring.
