HEAT-SENSITIVE ADHESIVE AGENT, HEAT-SENSITIVE ADHERING SHEET AND USE OF THE SHEET |
摘要 |
PROBLEM TO BE SOLVED: To obtain a heat-sensitive adhering agent having excellent adhesiveness and water resistance and readily peelable from the surface on a container such as a plastic bottle or a glass bottle by using an alkali solution and useful for a label, and a heat-sensitive adhering sheet. SOLUTION: This heat-sensitive adhering agent contains a copolymer obtained by copolymerizing 0.5-15 wt.% of an ethylenic unsaturated carboxylic acid with 85-99.5 wt.% of the other vinyl-based monomer, a rosin polymer and a solid plasticizer and has >=20 (KOH mg/g) acid value. Further, the adhering agent contains 20-150 pts.wt. of the rosin polymer and 100-400 pts.wt. of the solid plasticizer based on 100 pts.wt. of the copolymer. The heat-sensitive adhering sheet is obtained by coating the heat-sensitive adhering agent on the surface of a plastic film.
