HEAT-SENSITIVE ADHESIVE MATERIAL

摘要

PROBLEM TO BE SOLVED: To obtain a heat-sensitive adhesive material in which liquid stability of a heat-sensitive coating liquid is improved and tacky and adhesive force to polyolefin wraps and tacky and adhesive force to adherends at low-temperature environmental temperature and at low temperatures are improved in an adhesive label.

SOLUTION: The heat-sensitive adhesive material has a heat-sensitive adhesive layer containing at least a thermoplastic resin and a solid plasticizer on either one surface of a support. The heat-sensitive adhesive material layer is composed of the thermoplastic resin of a water-based emulsion and the solid plasticizer of a water-based dispersion and a ratio of volume average particle diameter of disperse particles of the solid plasticizer to volume average particle of emulsion particles of the thermoplastic resin is 70-150%.
