A photo-setting resin composition is here disclosed which comprises a photo-setting resin precursor and a dyestuff for uniformly coloring the photo-cured resin; and there is also disclosed a method for preparing a color filter by the use of this photo-setting resin composition.
Dyestuffs represented by the below-described formula (1), that is, dyestuffs formed of a chromophoric nucleus and a bisphenol introduced therein have excellent solubility in solvents and binder resins, and can provide color filters having excellent transmittance characteristics and durability.
wherein Dye represents a chromophoric nucleus, X represents a direct bond or a divalent connecting group, R¹ to R⁸ independently represent a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group or a substituted or unsubstituted alkoxyl group, R⁹ and R¹⁰ independently represent a hydrogen atom or a substituted or unsubstituted alkyl group, and n stands for an integer of 1 to 10, with the proviso that the total carbon number of R⁹ and R¹⁰ is at least 3.
