Abstract

The invention relates to the technical field of light curing, concretely to a photosensitive composition containing acridine oxide. The composition comprises 1-3 mass parts of the acridine oxide, 1-6 mass parts of Dacocur1173, Dacocur184 or a mixture of both, 10-80 mass parts of ethene unsaturated compound monomer and 10-80 mass parts of ethene unsaturated compound prepolymer. The invention provides the composition containing the acridine oxide together with an alpha-hydroxy ketone photoinitiator; and the composition has relatively high surface-curing and deep-curing performances and high photosensitive activity, can reduce use of the alpha-hydroxy ketone compound and therefore reduce odor resistance, is simple in preparation technology, and can substitute traditional photoinitiators and be used in light-curing formulas.

Description

technical field [0001] The invention relates to the field of photocuring technology, in particular to a photosensitive composition containing acridine oxides. 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] The photoinitiators often used in this field are α-hydroxy ketones, representative commercial products Dacocur1173 (2-hydroxy-2-methyl-1-phenylpropan-1 ketone) and Dacocur184 (2-hydroxy-1 -phenylcyclohexyl-1 ketone) are frequently used photoinitiators, and their structural formula is shown below: [0004] [0005] During the use of α...
