A diketone oxime ester compound shown in formula I and a manufacturing method therefor, and a photo-curable composition using the compound of formula I as a photoinitiator. The composition has extremely high light sensitivity and relatively low yellowing resistance when applied to prepare a color filter for a light resistance device such as a display screen.

Trans, trans-diketone oxime ester isomer, manufacturing method thereof and application thereof

A polyacrylate macromolecular photoinitiator, a synthesis method therefor, and the use thereof. The polyacrylate macromolecular photoinitiator is free of a component having a molecular weight of less than 1000, and can effectively avoid the introduction of a material having a mall molecular weight in the photoinitiator and the odor and migration contamination produced thereby, the general formula thereof being as shown in formula I.

Polyacrylate macromolecular photoinitiator, synthesis method therefor and use thereof

The present invention provides a photocurable composition prepared using mercapto benzophenone compounds as key raw materials. The present invention aims to solve the problems existing in the prior photo-curing technology that low-molecular photoinitiators are easy to remain and migrate, while macromolecular photoinitiators has low initiation efficiency due to a low content of effective components and also has the problem of certain migration. The photocurable composition in the present invention can be easily prepared and has high addition efficiency with ethylenically unsaturated compounds, and the photocurable composition obtained by addition has no residual mercapto and has features of high initiation activity and zero migration rates when it is used in photocurable coatings, binder and ink formula.
