BENZOPHENONE-CONTAINING OXIME ESTER-BASED COMPOUND CAPABLE OF IMPROVING LIGHT REACTIVITY BY ENERGY TRANSITION AT LIGHT IRRADIATION AND A PHOTOPOLYMERIZABLE COMPOSITION INCLUDING THE SAME

摘要

PURPOSE: An oxime ester compound is provided to improve photo reactivity by generating alkyl radical by light irradiation, thereby improving light reactivity and maximizing light efficiency.;CONSTITUTION: An oxime ester compound has a structure represented by chemical formula 1. In chemical formula 1, R1 is a methyl group, ethyl group, propyl group, isopropyl group, n-butyl group, isobutyl group, t-butyl group, pentyl group, hexyl group, heptyl group, or octyl group; each of R2 and R3 is hydrogen atom, halogen atom, or C1-6 alkyl group. A photopolymerizable composition comprises a photopolymerization initiator represented by chemical formula 1 and a photopolymerizable compound. The photopolymerizable compound is an acrylic copolymer with ethylenically unsaturated bond.;COPYRIGHT KIPO 2013
