Abstract
Abstract An adhesive composition which comprises a linear polyester-type polyethylene isophthalate, an amino compound containing an amino group of which a hydrogen atom is substituted by a functional methylol group, a curing catalyst and an oxide of a multivalent metal. When the adhesive composition is heated to cause curing, it will produce an adhesive layer having desirable physical properties of high-resistance to organic solvents and heat.
