PURPOSE:To produce a pressure-sensitive adhesive tape which does not emit objectionable odors and has excellent cohesive force and adhesion, by applying a specified radiation-curable pressure-sensitive adhesive compsn. to the surface of a tape substrate primed with a prim. or sec. amine and irradiating it with a radiation. CONSTITUTION:A radiation-curable heat-sensitive adhesive compsn. consisting of a radiation-curable liquid oligomer (e.g. an acrylic oligomer contg. an acryloyl group on its side chain) and a thiol compd. (e.g. 1,4-butanediol dithiopropionate) is used. A prim. or sec. amine (e.g. ethylamine or piperazine) is applied to a tape substrate (e.g. polyester film) to form an undercoat layer of 0.01-5g/m<2>. The above adhesive compsn. is then applied thereto and irradiated with a radiation to polymerize and reticulate the compsn., thus obtaining the desired pressure- sensitive adhesive tape. |
