Abstract

In order to solve the problem that corner breakage or edge breakage easily occurs in the cutting process flow of the existing IRCF, the invention provides the adhesive composition and the UV visbreaking cutting adhesive tape. The adhesive composition comprises 100.0 parts by mass of a (methyl) acrylate copolymer, 5.0 parts by mass of an aromatic polyurethane acrylate oligomer containing six vinyl groups, 0.5 to 5.0 parts by mass of a curing agent, and 3.0 parts by mass of a photoinitiator compounded by 1-hydroxycyclohexyl phenyl ketone and 2, 4, 6-trimethylbenzoyl diphenyl phosphine oxide. The UV visbreaking layer of the UV visbreaking cutting tape provided by the invention is formed by curing the adhesive composition provided by the invention. According to the UV visbreaking cutting adhesive tape, the adhesion layer and the base material have good adhesive force, the elastic Young modulus of the base material subjected to high-temperature treatment is high, and corner breakage or edge breakage cannot happen to IRCF in the cutting technological process.

Description

technical field [0001] The invention relates to a UV viscosity-reducing tape, in particular to an adhesive composition and a UV viscosity-reducing cutting tape. The UV viscosity-reducing cutting tape is applied to a silk screen printing process of an optical filter. Background technique [0002] The infrared cut filter (Infra-Red Cut-off Color-Filter, referred to as IRCF) is an optical component that constitutes a necessary high-performance camera module. It is located between the optical prism in the camera and the CMOS (Complementary Metal Oxide Semiconductor) sensor. In addition to infrared light above 630nm to improve imaging quality. The process route of cold processing to produce IRCF includes the following steps: coating, silk screen printing, cutting, laminating components and other processes. [0003] Generally, eliminating the stray light formed by the reflection of the gold wire in the camera module is beneficial to reducing ghost images and light spots during im...
