Embodiment Construction

[0029] The invention will be further illustrated by the following examples.

[0030] The specific formulation of the UV light-curable composition containing aminoketone photoinitiator provided in the following examples and applied to UV-curable offset printing ink is shown in Table 1:

[0031] Table 1

[0032]

[0033]

[0034] The composition prepared in this example was coated on a glass sheet, cured under the radiation of 365nm UV-LED lamp for 10s, 30s, 60s, 120s, and the surface dryness of the cured film was judged by the finger pressure method to characterize the curing speed.

Abstract

The invention provides a UV photocuring composition containing an aminoketone photoinitiator. The composition is suitable for a photocuring system, mainly suitable for a UV photocuring system, and particularly suitable for a UV photocuring ink and coating system; the UV photocuring composition containing the aminoketone photoinitiator is high in activity and can be subjected to radiation curing through a high-pressure mercury lamp and a UV-LED; surface layer curing of a coating can be achieved, and deep layer curing can also be achieved; and the UV photocuring composition has wide applicationprospects.

Description

technical field [0001] The invention relates to a UV photocurable composition containing an aminoketone photoinitiator. The composition is suitable for photocurable systems, mainly for UV curable systems, especially for UV curable inks and coating systems. Background technique [0002] Amino ketone compound is a highly efficient free radical (I) type photoinitiator, its effective absorption peak is 300-400nm, it can generate free radicals to initiate polymerization after being illuminated, and the photocuring speed is fast, which is suitable for deep curing of thick film. Especially suitable for fast curing of colored systems. [0003] There are two main types of amino ketones currently on the market, namely 2-phenylbenzyl-2-dimethylamine-1-(4-morpholinebenzylphenyl) butanone (UV369), 2-methyl-1- (4-methylthiophenyl)-2-morpholino-1-propanone (Irgacure907); UV369 has two obvious deficiencies, one is poor solubility in various unsaturated prepolymers and monomers, and the pre...
