Abstract

PURPOSE: To prepare an adhesive film giving low peel strength and high bond strength by forming, on a polyester film, an adhesive layer composed chiefly of a specific tereblock copolymer and a terpene phenolic resin.
CONSTITUTION: The objective film can be obtained by forming, on a polyester film such as a polyethylene therephthalate film, etc., a heat-sensitive adhesive layer, which consists mainly of a mixed comnposition of A) a tereblock copolymer constituted of polystyrene and polybutadiene (preferably having a weight ratio styrene/ butadiene of 25/75W45/55 and an average molecular weight of 50,000W300,000), and B) a terpene phenolic resin (preferably having a softening point of 110W 150°C). The weight ratio A/B is pref. 35/65W65/35. The adhesive composition is preferably incorporated with an antioxidant to impart durability.
EFFECT: Provided with good workability.
