Abstract

The invention provides a photoinitiator composition, a photocuring composition and a product containing the photoinitiator composition and the photocuring composition. The photoinitiator composition includes: an acyl carbazole derivative and an oxime ester compound; wherein the acyl carbazole derivative is selected from one or more of a group consisting of a compound as shown in a formula I, a compound as shown in a formula II-A, a compound as shown in a formula II-B, a compound as shown in a formula II-C, a compound as shown in a formula II-D, a compound as shown in a formula II-E, a compound as shown in a formula II-F, a compound as shown in a formula II-G, a compound as shown in a formula II-H and a compound as shown in a formula II-I; the oxime ester compound is a compound shown in a formula (III). In the photoinitiator, the acyl carbazole derivative with a specific structure and the oxime ester compound are matched for use, through the synergistic effect of the acyl carbazole derivative and the oxime ester compound, the photoinitiator has excellent sensitivity and thermal stability, and meanwhile, the photocuring efficiency of the photoinitiator can be greatly improved, and the developing effect of the photoinitiator is good.

Description

technical field [0001] The invention relates to the technical field of photocuring, in particular to a photoinitiator composition, a photocurable composition and products containing the photoinitiator composition. Background technique [0002] Photocuring technology has been widely used since its appearance in the 1970s. For example, UV photocuring technology has been widely used in the fields of coatings, printing inks, and electronic device manufacturing. Among them, the key factors affecting curing efficiency are photoinitiators and their co-used Co-initiator components, such as sensitizers. Carbazolyl oxime esters are an important class of oxime ester photoinitiators, and are well known, researched and used by those skilled in the art because of their relatively high sensitivity. In order to improve the color saturation or hiding power, the pigment content in the light-curing formula is getting higher and higher, especially the black photoresist with high pigment conten...
