摘要:
Provided is a heat-resistant shrinkable adhesive film capable of reducing or preventing defects such as shrinkage when exposed to a high temperature even when bonded in a highly stretched state. A heat-resistant shrinkable adhesive film according to one embodiment of the present disclosure includes (A) an acid functional group-containing (meth)acrylic polymer having a glass transition temperature of about 25°C or lower, and (B) an acid or base functional group-containing (meth)acrylic polymer having a glass transition temperature of about 50°C or higher, the mixing ratio of the component (A) being larger than the mixing ratio of the component (B), and the adhesive film including an adhesive layer with a crosslinked structure derived from a metal coordination bond crosslinking agent and can be stretched to an area magnification of 4 times or more
