Problems solved by technology
These blue-UV absorbers compete with the photoinitiator for incident light, resulting in reduced initiation capability
Although OXE-01 diphenylsulfide ketoxime ester photoinitiator absorbs longer wavelength light, it is still affected

The invention discloses a diphenyl sulfide ketoxime ester compound, a preparation method, a composition and application. A diphenyl sulfide ketoxime ester photoinitiator has the characteristics of high sensitivity and capability of absorbing long-wavelength light. On one hand, long-wavelength light can be absorbed to increase deep curing, and on the other hand, other short-wavelength ultraviolet light absorbers in the formula can be prevented from competing for incident light with the photoinitiator. The compound has initiation capability of long wavelength band, and can be used independently or matched with other photoinitiators for use.
Description
technical field [0001] The invention relates to a diphenyl sulfide ketoxime ester compound, a preparation method, a composition and an application. The diphenyl sulfide ketoxime ester compound of the present invention is used in photocuring, optical or electronic industries. Background technique [0002] Photoinitiators are important chemicals in the photocuring industry, such as coatings, inks, adhesives, photoresists and other fields. Photocurable material monomers must be added with a photoinitiator to stimulate the unsaturated groups in the photocurable material to undergo polymerization under the irradiation of a light source of a certain wavelength, and cause the photocurable material to cure. A good photoinitiator is the key to the success of photocuring technology. Traditional photoinitiators include benzoins, acetophenones, benzophenones, thioxanthones, acyl phosphine oxides, aromatic diazonium salts, ferrocenes, triazoxides, hexaaryl diazides, Imidazoles and oxi...
