<p>PURPOSE:To provide a tacky adhesive tape having excellent adhesivity and holding power by fully making use of the characteristic properties of a tacky adhesive layer. CONSTITUTION:A closed-cell cellular polybutadiene material having a density of 0.05-0.5g/cm<3> is used as the substrate of the objective tacky adhesive tape. The tacky adhesive agent to be used in the tape is produced by compounding an acrylic copolymer, a polymer containing hydrolyzable silicon group and a polyfunctional isocyanate compound. A polymerizable unsaturated carboxylic acid is used as a component of the raw material monomers for the acrylic copolymer.</p> |
