Problems solved by technology

[0008] It is very difficult to satisfy high wear resistance and low shrinkage at the same time, so the application fields of traditional photocurable resin compositions are limited because although they have high wear resistance, they do not have high transparency, Low shrinkage, and antistatic
Traditional light-curable resin compositions are especially not suitable for optical discs

Abstract

The present invention relates to a kind of photocurable resin composition, more specifically, a kind of acrylate monomer containing acrylate oligomer, having 4 or less functional groups, photopolymerization initiator, hardness of formula (1) A light-cured resin composition of a reinforcing agent, m-terphenyl of formula (2), and a colloidal antistatic agent. The composition has high antistatic property, good light transmittance, high hardness and low shrinkage rate.

Description

field of invention [0001] The present invention relates to a photocurable resin composition having antistatic properties, and more particularly to a photocurable resin composition with low shrinkage and improved tilt performance. Background technique [0002] Plastics have been widely used in electrical, electronic and optical materials. Such plastics include, for example, vinyl chloride resin (PVC), methyl methacrylate resin (PMMA), polycarbonate resin (PC), acrylonitrile-butadiene-styrene resin (ABS) and polyethylene terephthalate Ethyl ester resin (PET). These plastics offer various advantages such as light weight, low production cost, breakage resistance and good moldability. Therefore, they can be used to replace glass and metal products. However, plastic surfaces have poor abrasion and chemical resistance. Therefore, its surface is usually treated or coated to improve these poor properties. For example, a light-curing resin is used for surface treatment of plastic...
