Abstract

The invention relates to the technical field of photo-curing, and particularly relates to a photosensitive composition containing acridine bifunctional photoinitiators. The photosensitive composition comprises the following components according to mass: 1-8 part(s) of acridine derivative photoinitiators, 10-80 parts of ethylene unsaturated compound monomers and 10-80 parts of ethylene unsaturated compound prepolymers. The photosensitive composition provided by the invention is high in photosensitive activity, can avoid environmental and security problems brought by a photosensitive composition with micromolecule photoinitiators, needs a simple preparation process, and can replace the conventional photoinitiator to be applied to a photo-curing formula.

Description

technical field [0001] The invention relates to the technical field of photocuring, in particular to a photosensitive composition containing an acridine bifunctional photoinitiator. Background technique [0002] UV curing refers to the curing process of monomer, oligomer or polymer matrix induced by ultraviolet light. This technology is widely used in modern microelectronics technology. The photocurable composition in the UV curing system is mainly composed of single It consists of three parts: body, prepolymer and photoinitiator, among which photoinitiator is the most important factor affecting the photosensitive performance of photocurable composition. [0003] Traditional photoinitiators such as benzoin derivatives, bibenzoyl ketals, α,α-dialkoxyacetophenones, benzophenone / amines, Michler's ketone, thiazolone / amines, etc., among which Dacocur1173 (2-Hydroxy-2-methyl-1-phenylpropan-1-one) and Irgacure907 (2-morpholino-2-methyl-1-methylthiophenylpropan-1-one) are commonly ...
