Abstract

See full text

A multilayer card has (i) an opaque polyester film substrate (1) containing 0.2 to 30% by weight, relative to the total weight of the substrate, of at least one copolyesterether, (ii) an ink-receptive layer (2) on at least one surface of the substrate, and (iii) a cover layer (4) on the surface of the ink-receptive layer and/or surface of the substrate. The presence of the copolyesterether in the substrate reduces the tendency of the card to delaminate in use. Suitable for use, inter alia, in identification, magnetic, credit, pre-paid and smart cards.
