Problems solved by technology

For example, in terms of displays, large screens and high-definition pictures are the direction of development, and the carbazole oxime ester photoinitiators disclosed in patent documents such as CN101508744A are not pure enough in color due to their yellowing properties. It cannot meet the requirements of large-screen high-definition displays, and gradually cannot meet the application needs of high-end color filters and LEDs

Abstract

The invention relates to a photoinitiator of diphenyl sulfide oxime esters. The photoinitiator has a chemical structure shown as a formula (1) in the specifications, is excellent in application performance, high in photosensibility, free of yellowing and good in dissolubility, and has the advantages of greatly increasing a photo-curing performance when applied to photosensitive compositions and obviously increasing the performance and production efficiency in the photosensitive composition application field, such as preparation of color filters. The invention further relates to a preparation method of the photoinitiator and application of the photoinitiator to the photosensitive compositions.

Description

technical field [0001] The invention relates to the technical field of photoinitiators, in particular to a diphenyl sulfide oxime ester photoinitiator and its preparation method and application. Background technique [0002] Photocuring refers to the curing process of monomer, oligomer or polymer matrix under light induction. This technology has a wide range of applications in modern microelectronics technology, such as photocurable ink, liquid crystal panel packaging, photosensitive printing plate, Filters and photoresists, etc. The photoinitiator is the most important factor affecting the photosensitivity of the photocurable composition, that is, the photosensitive composition. So far, the development and application of photoinitiators has covered a variety of compound categories, such as benzoin derivatives, biphenyl ketals, α, α-dialkoxyacetophenones, benzophenones / amines, Michler's ketones, thiazolones / amines, aromatic diazonium salts, triazoxides, oxime esters, etc.,...
