Title:
PRESSURE SENSITIVE ADHESIVE SHEET FOR WET ELECTROPHOTOGRAPHIC PRINTING
Document Type and Number:
Japanese Patent JP3812870
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To ensure good adhesion of a toner to a recording sheet, to attain good shift of the toner to the recording sheet, to prevent the contamination of a pressing rolls with the toner due to shift during passing through the rolls and to avoid illegibleness of information due to the transfer of the toner to other face when a pressure sensitive adhesive sheet is opened.
SOLUTION: A layer of a pressure sensitive adhesive obtained by graft- polymerizing 5-20 wt.% methyl methacrylate on natural rubber is formed on both faces of a base sheet by 3-10 g/m2 per one face. In other way, a layer of a pressure sensitive adhesive obtained by graft-polymerizing 5-20 wt.% methyl methacrylate on natural rubber is formed on one face of a base sheet by 3-10 g/m2 and a layer of a polyethylene-base resin having a metallic ionic bond between polymer chains is formed on the other face. The former sheet is suitable for a pressure sensitive adhesive postcard folded in V shape and the latter sheet is suitable for a pressure sensitive adhesive postcard folded in Z shape.
