Problems solved by technology

However, most of the existing light-curing systems have poor absorption capacity for LED light sources, and often cannot be cured or are incompletely cured. A few applicable systems have more restrictions on the types of components and are expensive

[0093]

[0094] The photocurable composition of the present invention can be obtained by weighing each component according to the amount and mixing them uniformly.

[0095] At present, commercially available products in the field of light curing, especially mid-to-high-end products, are mainly imported. Most of these products have patented technology and high product prices. However, domestic companies lack core technologies and independent intellectual property rights. Under strict technical barriers, enterprise development is difficult. Even the R&D layout has been greatly restricted. Through the optimization of the components, the hybrid photocurable composition obtained has a large photosensitive wavelength range and good photocuring effect, and can combine the advantages of free radical and cationic photocurable systems, and can be applied in such as paints, coatings, inks, moldings, etc. Materials and other aspects have been applied, with strong technical and market co...

Abstract

The invention discloses a free radical-cation hybrid photocurable composition, comprising: anthracene ester sensitizers, selected from compounds having the structure shown in formula (I) and / or compounds with the compound of formula (I) as the main structure Macromolecular compounds; cation-reactive compounds and free-radical-reactive compounds, including at least one unsaturated double bond-containing compound and at least one epoxy-containing compound; cationic photoinitiators; optionally, free-radical photoinitiators agent. Through component optimization, the composition can combine the advantages of free radical and cationic photocuring systems, and has excellent response to light sources in the wavelength range of 200-500nm, fast curing speed, small shrinkage, development and pattern integrity Good, and the hardness of the cured film is high, and the adhesion on the substrate is strong.

Description

technical field [0001] The invention belongs to the field of organic photocuring, and in particular relates to a radical-cation hybrid photocuring composition and its application in the field of photocuring. Background technique [0002] UV curing technology is widely used in the fields of electronic material preparation and other fields. According to the different mechanism of initiating polymerization, it can be divided into two categories: free radical type and cationic type. Both have their own advantages and disadvantages. Free radical polymerization has a wide range of raw materials and high formula adjustability, but the curing shrinkage rate is large, which is easy to cause oxygen inhibition; cationic polymerization does not have the problem of shrinkage rate and oxygen inhibition, but the curing speed Slow and expensive. Free radical-cation hybrid photocuring system is considered to be an effective way to combine the advantages of both. However, practice shows tha...
