Title:
PHOTOSENSITIVE RESIN COMPOSITION, CURED PRODUCT, COLOR FILTER, DISPLAY DEVICE MEMBER AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/182232
Kind Code:
A1
Abstract:
Provided is a photosensitive resin composition which exhibits excellent storage stability and curing reaction properties and which gives a cured product having excellent solvent resistance. This photosensitive resin composition contains an alkali-soluble resin, a photopolymerizable compound, a photopolymerization initiator and a solvent. The alkali-soluble resin is a copolymer that contains a constituent unit (A) derived from an unsaturated carboxylic acid or an anhydride thereof and a constituent unit (B) derived from a compound represented by formula (1) (in the formula, R1 and R2 each denote a hydrogen atom or an alkyl group having 1-7 carbon atoms. X denotes a single bond, a divalent hydrocarbon group, or the like. Y denotes a methylene group or ethylene group that may have an alkyl group having 1-3 carbon atoms as a substituent group, or the like. n is an integer from 0 to 7). The copolymer has an exothermic peak top temperature of 180-220°C, which appears when the temperature is increased at a rate of 5°C/minute using a differential scanning calorimeter.
