<p>PROBLEM TO BE SOLVED: To provide a water-dispersion type emulsion self-adhesive which permits formation of a light-shielding self-adhesive tape having excellent light-shielding property while using a water-dispersion type self-adhesive, good adhesiveness such as constant load peelability, retention power and repulsion resistance with respect to various adherends, and suitable removability.SOLUTION: The light-shielding self-adhesive composition contains a colorant and a tackifier resin in specific ratios in a water-dispersion type acrylic self-adhesive composition having acrylic copolymer emulsion particles dispersed in an aqueous medium, and has a gel fraction of 20 to 70% after dried and crosslinked. By using the above self-adhesive composition, a self-adhesive tape can be achieved, which has suitable adhesiveness and removability with respect to various adherends, while exhibiting excellent light-shielding property regardless of being the water-based self-adhesive composition.</p> |
