The invention provides appearance characteristics excellent, humidification can be suppressed to preserve under albefaction (moisture absorption albefaction) and there is the releasable adhesive sheet of excellent scratch resistance and static electricity resistance.A kind of adhesive sheet, in at least one side side of transparent film substrate, there is acrylic adhesive layer, it is characterized in that, described transparent film substrate has the basal layer comprising resin material and the overlay coating be arranged on the first surface of this basal layer, described overlay coating is made up of Polythiophene, acrylic resin and melamine class linking agent, mean thickness Dn ave be 2 ~ 50nm, the deviation delta D of thickness is less than 40%, described acrylic adhesive layer is the binder layer formed by stripping water-dispersed acrylic class binder composition again, the described water-dispersed acrylic of stripping again class binder composition contains acrylic emulsions type polymkeric substance, described acrylic emulsions type polymkeric substance is formed using (methyl) alkyl acrylate (A) with containing carboxyl unsaturated monomer (B) as the starting monomer of necessity, in starting monomer total amount, the content of (methyl) alkyl acrylate (A) is 70 ~ 99.5 % by weight, content containing carboxyl unsaturated monomer (B) is 0.5 ~ 10 % by weight, and use the reactive emulsifier in the molecule containing free redical polymerization functional group to carry out being polymerized and obtaining. |
