The present invention provides adhesive compositions of improved adhesion which comprise (a) an ether-type polyester obtained by the heat treatment of a polyethylene-terephthalate with at least one glycol having at least 3 carbon atoms to interchange the ethylene glycol components in the polyethylene-terephthalate, and (b) a linear thermoplastic high molecular weight urethane elastomer. Embodiments include an adhesive composition, comprising component (a) and component (b) plus (c) a polyisocyanate and an adhesive coating composition comprising an ether-type polyester obtained by the heat treatment of a polyethylene terephthalate with at least one glycol having at least 3 carbon atoms to interchange the ethylene glycol components in the polyethylene terephthalate, a polyisocyanate and a pigment.
An adhesive composition consisting essentially of an ether group containing polyester obtained by the heat treatment of a polyethylene terephthalate with at least one glycol having at least 3 carbon atoms to substitute the ethylene glycol components in the polyethylene terephthalate by said glycol having at least 3 carbon atoms, wherein 30 to 100% of the ethylene glycol components in the polyethylene terephthalate are substituted by said glycol having 3 or more carbon atoms
