Document Type and Number:
WIPO Patent Application WO/2023/182467
Kind Code:
A1
Abstract:
One embodiment of the present invention relates to a multilayer body, a method for producing a multilayer body or an adhesive composition; and this multilayer body comprises a layer (A) that contains a polyethylene terephthalate or a biodegradable polymer and an adhesive layer (B) that contains an adhesive composition. With respect to this multilayer body, at least a part of the adhesive layer (B) is in contact with the layer (A); the adhesive composition contains a graft-modified product of at least one base polymer that is selected from among polyolefins by means of a carbodiimide monomer having a carbodiimide group and a polymerizable double bond; carbodiimide groups are contained in an amount of 0.1 to 50 mmol per 100 g of the adhesive composition; and the adhesive composition has a density of 0.870 to 0.940 g/cm3.
