A composition comprising (1) a hydrolyzed ethylene-vinyl acetate copolymer having an ethylene content of 20 to 60% by mole and a degree of hydrolysis in the vinyl acetate component of at least 95% by mole and (2) a secondary or tertiary alkali metal phosphate; the alkali metal content being from 15 to 250 ppm of the hydrolyzed copolymer (1) and the phosphorus content being from 5 to 70 ppm of the hydrolyzed copolymer (1). The composition of the invention is excellent in adhesive strength to unsaturated carboxylic acid-modified polyolefins, and therefore the laminate having the structure the polyolefin layer/the unsaturated carboxylic acid-modified polyolefin layer/the hydrolyzed ethylene-vinyl acetate copolymer composition of the invention layer has excellent adhesive strength between the unsaturated carboxylic acid-modified polyolefin layer and the layer of the composition of the present invention.
A composition consisting essentially of
