PRESSURE-SENSITIVE ADHESIVE COMPOSITION HAVING EXCELLENT FIXING PROPERTY OF INKJET INK AND INFORMATION-CARRYING SHEET USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition which has excellent water resistance of inkjet inks printed thereon and which does not cause ink offset and has excellent ink fixing properties and to provide an information- carrying sheet having an adhesion layer of the pressure-sensitive adhesion composition.;SOLUTION: The pressure-sensitive adhesive composition is used, which is obtained by blending a natural rubber-based adhesive base with 10-50 parts by mass of silica gel which lacks an affinity for the adhesive base and which has an average particle diameter of 1-5 μm and an oil absorption of 100 ml/100 g or more and 10-50 parts by mass of a cationic substance based on 100 parts by mass of the solid content of the adhesive base.;COPYRIGHT: (C)2001,JPO
