Compound or its tautomer, metal complex compound, colored photosensitive curing composition, color filter, and production
Abstract:
The invention provides a colored photosensitive curing composition useful for color filters in primary colors, including blue, green, and red, having a high molar absorption coefficient and allowing a reduction in film thickness and superior color purity and fastness; the colored photosensitive curing composition including, as its colorant, a dipyrromethene-based metal complex compound or a interconvertible isomer thereof, obtained from a metal or metal compound and a dipyrromethene-based compound represented by Formula (III): wherein R2 to R5, R7 represent a hydrogen atom or a substituent group; Ma represents a metal or metal compound; X3 represents NR, a nitrogen, oxygen or sulfur atom; X4 represents NR, an oxygen or sulfur atom; Y1 represents NR, a nitrogen or carbon atom; Y2 represents a nitrogen or carbon atom; R8 and R9 represent a substituent group; X5 represents a group that can bond to Ma; and a is 0, 1, or 2.
