Abstract

A biodegradable laminate, wherein a polyvinyl alcohol resin layer is laminated on at least one surface of an aliphatic polyester resin layer through an adhesive layer, which is excellent in biodegradability and gas barrier properties, and also excellent in interlayer adhesiveness, is obtained. The adhesive layer comprises, as a main component, a polyester resin (A') which has a polar group and is obtained by graft polymerization of an α,β-unsaturated carboxylic acid or an anhydride thereof on a biodegradable polyester resin (A) comprising at least one structural unit selected from structural units represented by the following general formulae (1), (2), and (3):
