ABSTRACT:
Pressure-sensitive adhesive tape which has both high adhesion and high cohesion values and adheres strongly to automotive paints and to rubber or plastic foam layers, thus showing great promise for adhering plastic molding strips to the sides of automobiles. The adhesive layer of the novel tape may be made by photopolymerizing (1) acrylic acid ester of non-tertiary alcohol, the alkyl groups of which have an average of 4-14 carbon atoms and (2) N-vinyl-2-pyrrolidone in an amount within 15-50 parts by weight of the total monomers (1) and (2), preferably 25-35 parts.
