发明名称 PRESSURE-SENSITIVE ADHESIVE COMPOSITION
摘要 PURPOSE:To provide a pressure-sensitive adhesive compsn. which exhibits excellent characteristics by the crosslinking with ultraviolet light or electron beam irradiation, by incorporating an oligomer capable of being radical-crosslinked by irradiation with ultraviolet light or electron beams, in an alkyl (meth)acrylate copolymer. CONSTITUTION:1-50pts.wt. oligomer having an MW of 1,000-20,000 and at least two unsaturated bonds per molecule, which can be radical-crosslinked by irradiation with ultraviolet light or electron beams, and 0-10pts.wt. photosensitizer are blended with 100pts.wt. copolymer having an MW of 100,000-600,000 and mainly composed of an alkyl acrylate or methacrylate. When the resulting pressure-sensitive adhesive compsn. is radical-crosslinked by irradiation with ultraviolet light or electron beams, it exhibits the optimum viscoelastic properties for displaying good bonding properties such that initial modulus is 0.5- 20kg/cm<2> in a stress-strain curve under tension at a pulling rate of 50mm./min.
