Document Type and Number:
Japanese Patent JP3765207
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide pressure-sensitive adhesive sheets containing a hygroscopic powder in a pressure-sensitive adhesive layer, and a method for preparing the same.
SOLUTION: In a pressure-sensitive adhesive sheet having a substrate and a pressure-sensitive adhesive layer, the pressure-sensitive adhesive layer contains a hygroscopic powder and a moisture absorbing agent. Further, in preparing a pressure-sensitive adhesive sheet having a substrate and a pressure-sensitive adhesive layer which contains a hygroscopic powder and a moisture absorbing agent, first, the hygroscopic powder and the moisture absorbing agent are mixed and the resulting mixture is mixed with a pressure sensitive adhesive to form a coating liquid and then, the coating liquid is directly coated on the substrate or coated on a release sheet and then, the release sheet is laminated on the substrate to prepare a pressure-sensitive adhesive sheet.
