HARDENABLE TACKY ADHESIVE SHEET AND METHOD FOR BONDING MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a hardenable tacky adhesive sheet which shows tacky adhesiveness at ordinary temperature, can be hardened by irradiation with light, has excellent adhesiveness to an adherend and is applicable even to a lowly heat-resistant adherend. SOLUTION: This sheet is obtained by using a tacky adhesive polymer such as an acrylic polymer. The sheet contains an epoxy compound and a cationic photopolymerization catalyst which induces the cationic photoreaction for the ring opening of the epoxy groups so that the absorptivity of the sheet to light at a wavelength of 350nm may fall in the range of 0.001-0.2per 100μm of sheet thickness.
