发明名称 PRESSURE-SENSITIVE ADHESIVE TAPE
摘要 PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive tape which excels in adhesiveness, cohesiveness, and stability and is safe for the health without skin irritation. SOLUTION: The pressure-sensitive adhesive tape has a pressure-sensitive adhesive layer obtained by coating a nonaqueous pressure-sensitive adhesive containing a copolymer obtained by polymerizing a (meth)acrylic monomer having an acetoacetyl group in the molecule and one or more (meth)acrylic monomers selected from the group consisting of 2-ethylhexyl acrylate, butyl acrylate, diacetoneacrylamide, methyl methacrylate, methyl acrylate, ethylene glycol dimethacrylate, diethylene glycol dimethacrylate, tetraethylene glycol dimethacrylate, and hexaethylene glycol dimethacrylate in a nonaqueous solvent together with a plasticizer on the entire top surface or part of the top surface of a substrate, and the pressure-sensitive adhesive layer does not contains a percutaneously absorbing agent, and the copolymer is self-crossinked by the acetoacetyl group.
