ULTRAVIOLET LIGHT-CURABLE TYPE REPEELABLE PRESSURE SENSITIVE ADHESIVE COMPOSITION AND REPEELABLE ADHESIVE-PROCESSED PAPER

摘要

PROBLEM TO BE SOLVED: To provide an ultraviolet light curable type repeelable pressure sensitive adhesive composition capable of obtaining a stable repeelable property. also without having the change of bonding strength over time even under a high temperature and high humiity, also having less change in the bonding strength of cured film even on changing the irradiation amount of the ultraviolet light on curing, without destroying a substrate material applied with the adhesive on using, i.e., on peeling and exhibiting the stable repeeling property.;SOLUTION: This ultraviolet light curable type repeelable pressure sensitive adhesive composition containing an ultraviolet light curable component and a photopolymerization initiator is characterized in that the ultraviolet light curable component contains ethoxylated trimethylolpropane triacrylate added with ≥6 mol ethylene oxide groups per one molecule.;COPYRIGHT: (C)2007,JPO&INPIT
