Embodiment Construction

[0016] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below in conjunction with examples.

[0017] The present application will be described in further detail below in conjunction with specific examples, and these examples should not be construed as limiting the scope of protection claimed in the present application.

[0018] As described in the background technology section, most photocuring systems in the prior art have poor curing performance under the irradiation of light sources in the wavelength range of 200-500 nm, and cannot meet the curing requirements under mercury lamps and LED light sources at the same time. In order to solve the above problems, the present invention provides a photocurable composition, which includes a coumarin sensitizer, a reactive compound, and a photoinitiator; the reactive comp...

Abstract

The invention provides a photocurable composition and application thereof. The photocurable composition comprises a coumarin sensitizer, a reactive compound and a photoinitiator, wherein the reactivecompound comprises at least one unsaturated double bond-containing compound and / or at least one epoxy group-containing compound; the coumarin sensitizer is one or more of compounds shown in a formula(I), a formula (II) or a formula (III) in the description. The photocuring composition has good photosensitive activity on a mercury lamp light source or an LED light source, the compatibility of allthe components of the composition is good, a coating is smooth and flat and free of pin holes, and the adhesiveness of the photocuring composition to base materials such as plastic, metal and ceramicafter curing is good.

Description

technical field [0001] The invention relates to the field of organic photocuring, in particular to a photocuring composition and its application. Background technique [0002] UV curing technology has a very wide range of applications in the preparation of electronic materials and other fields. According to the different mechanism of initiating polymerization, it can be divided into two categories: free radical type and cationic type. The application of both has its own emphasis. At the present stage, high-pressure mercury lamps (usually in the wavelength range of 200-360nm) are the main light sources for light-curing systems. However, high-pressure mercury lamps consume more energy and pollute the environment, and their use is increasingly restricted. LED light sources (usually in the wavelength range of 320-500nm) have low damage, high energy and low consumption, and are considered to be able to replace mercury lamps as a good substitute for conventional light sources in p...
