PURPOSE:To obtain the titled adhesive which has excellent adhesion and cohesive force, does not cause lifting and little changes with time, by blending a chain transfer agent and a high-molecular rubbing polymer with a radiation- curable liquid oligomer. CONSTITUTION:0.2-20pts.wt. chain transfer agent and 0.1-5pts.wt. high-molecular rubbery polymer having an MW of 300,000 or above are blended with 100pts. wt. radiation-curable liquid oligomer contg. unsaturated double bonds. Examples of the chain transfer agents are thiol compds. such as butyl mercaptan and ethylene glycol dithioglycolate; disulfides such as diphenyl disulfide; and halides such as carbon tetrachloride. Examples of the rubbery polymers are acrylate copolymers, chloroprene polymer and ethylene/vinyl acetate copolymer.
