ONE-TIME RELEASABLE PRESSURE-SENSITIVE-ADHESIVE RECORDING PAPER

摘要

PROBLEM TO BE SOLVED: To provide one-time releasable pressure-sensitive-adhesive recording sheet having excellent offset printing suitability and excellent toner fixing and toner transfer properties by a wet electrophotographic method. SOLUTION: The one-time releasable pressure-sensitive-adhesive recording sheet has a pressure-sensitive adhesive layer exhibiting peelable adhesion by pressurization without exhibiting stickiness and adhesiveness in a normal state on at least one surface of a support. The one-time releasable pressure-sensitive-adhesive recording sheet is characterized as follows. The pressure-sensitive adhesive layer contains at least natural rubber grafted with an unsaturated monomer, a pigment and an adhesive. The amount of the pigment component is 10-25 mass% based on the total amount of the pressure-sensitive adhesive layer. The amount of the adhesive component is 5-10 mass% based on the total amount of the pressure-sensitive adhesive layer and≥20 mass% of the adhesive component is polyvinyl alcohol having≥80% degree of saponification.
