摘要:
The object of the present invention is to provide a heat-sensitive adhesive material having improved delivery properties and a superior adhesive strength. The objective heat-sensitive adhesive material in which an adhesive layer comprising mainly an adhesive is coated over a support and a heat-sensitive adhesive layer having developed adhesion by heating and maintaining the developed adhesive strength is coated over the adhesive layer, has Clark stiffness set by JIS P-8143 of 30 m3/100 to 180 cm3/100 in a longitudinal direction and a coefficient of static friction between a heat-sensitive layer and a polyethylene terephthalate (PET) film of 0.90 or less.
