AQUEOUS EMULSION-TYPE HEAT-SENSITIVE ADHESIVE, HEAT-SENSITIVE ADHESIVE LABEL AND LABELED CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide an aqueous emulsion-type heat-sensitive adhesive achieving both adhesiveness and blocking prevention and a heat-sensitive adhesive label achieving both adhesiveness and blocking prevention. SOLUTION: The aqueous emulsion-type heat-sensitive adhesive of the present invention is characterized in containing a base polymer and a water-soluble solid organic compound having a molecular weight of 130 to 2,000 and a melting point of 50 to 300°C, in which the content of the water-soluble solid organic compound is 0.2 to 25 pts.wt. based on 100 pts.wt. of total solid content of the base polymer. In addition, the base polymer is preferably formed from an acrylic resin and an olefin resin. Furthermore, mixing ratio of the acrylic resin and the olefin resin is preferably such that the former/latter (weight ratio on the basis of solid content) is 10/90 to 90/10.
