Title:
ACTIVE ENERGY RAY-CURABLE COMPOSITE RESIN COMPOSITION, ACTIVE ENERGY RAY-CURABLE COMPOSITE RESIN ADHESIVE USING THE COMPOSITION, AND ADHESIVE TAPE FOR BONDING OPTICAL MEMBER
Document Type and Number:
Japanese Patent JP2018048274
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a composite resin composition curable by irradiation with active energy rays, which suppresses foaming associated with a volatilized material derived from plastics under high temperature or high temperature and high humidity conditions and which achieves water vapor barrier property and low dielectric property, an adhesive using the resin composition, and an adhesive tape for bonding optical members, which is cured by active energy rays.SOLUTION: A cured product having excellent foaming resistance, water vapor barrier property and low dielectric property, or an adhesive tape for bonding an optical member can be obtained by: compounding a urethane acrylate resin having less than 2 functional groups, a polyisobutylene resin having a number average molecular weight of 300 to 100,000, and a crosslinking agent to give a crosslinked point density of 0.03 to 0.15 mmol/g; and curing the obtained composite resin with active energy rays.SELECTED DRAWING: None
