Abstract

A colored curable resin composition contains an adhesive resin (A), a dye (B-1), a pigment (B-2), a polymeric compound (C), a polymerization initiator (D) and a solvent (E), wherein the dye (B-1) comprises compounds as shown in the following formula (I). In the formula (I), L represents a divalent alkyl containing at least one fluorine atom and with a carbon number of 1-20; X represents an atom of the 16th group of the periodic table, -N(R10)-, or -C(R10)(R11)-; R1-R12 independently represent hydrogen atoms, monovalent alkyls with a carbon number of 1-20; and M represents an alkali metal atom.

Description

Technical field [0001] The present invention relates to a colored curable resin composition. Background technique [0002] Dyes are used, for example, in fields such as fiber materials, liquid crystal display devices, and inkjet printers to display colors using reflected light or transmitted light. As such dyes, coumarin compounds (compounds represented by the following formula) such as coumarin 6 are known (JP2006-154740-A Example 8). [0003] [0004] In the process of producing a color filter from a colored curable resin composition containing the above-mentioned compound, a problem arises in sublimation of the colorant. As a method of suppressing sublimation of a colorant, a method of dimerizing the colorant is known. However, compared with the colored curable resin composition containing the monomer of the colorant, the colored curable resin composition containing the compound which dimerized the colorant has a problem in that foreign matter is easily precipitated....
