Adhesive sheet

PURPOSE:An adhesive sheet having excellent releasability, prepared by providing a layer of water-soluble or emulsion type acrylic adhesive whose adhesive strength has been controlled by the addition of a pigment having a specific adsorptive capacity for Methylene Blue, between a skin material and a release sheet. CONSTITUTION:An adhesive solution (A) is obtained by mixing (1) 100pts.wt. (solids) of a water-soluble or emulsion type acrylic adhesive with 2-20pts.wt. of a pigment having an adsorptive capacity for Methylene Blue, (2) of at least 50%, such as synthetic aluminum silicate or synthetic magnesium silicate. Then, the adhesive sheet is produced by coating the adhesive solution (A) onto a release sheet consisting of a release sheet base 4 and a silicone release agent layer 3, drying the coated film to form an adhesive layer 2, and then sticking a skin material 1 onto the adhesive layer 2, for example, by press rolls. EFFECT:Break of adherent, migration of adhesive to adherent and break of adhesive sheet do not occur, when the adhesive sheet once applied to an adherent is released.
