Title:
Cyclopentane dione oxime ester and its applications
Document Type and Number:
Japanese Patent JP6328642
Kind Code:
B2
Abstract:
The present invention relates to compounds represented by general formulas I, IIa, lib and III and preparation method therefor. Ar1 is substituted o-arylene or o-heteroarylene; Ar2 is bis(o-arylene) or bis(o-heteroarylene) connected in various ways; X is O, S or NR19; Y1 is O, S, NR20, BR20, CR15R16, SiR15R16, S=O or C=O; Z1 is a axial bond, C1-C10 alkylene or arylene; R1, R15, R16, R18, R19 or R20 is respectively hydrogen atom, alkyl or alkoxy, alkyl or alkoxy substituted with any group, cycloalkyl, aryl substituted with any group or acyl. The present invention also relates to a photocurable composition containing compounds represented by general formulas I, IIa, lIb and III as photoinitiator. The composition presents very excellent comprehensive performance when used for preparing photoresist elements such as a color filter for display screen.
