Document Type and Number:
WIPO Patent Application WO/2017/163817
Kind Code:
A1
Abstract:
The present invention relates to a surface-treated metal plate for polyolefin resin bonding, which is obtained by laminating an adhesive layer on at least one surface of a metal substrate, with a chemical conversion coating film being interposed therebetween. This surface-treated metal plate for polyolefin resin bonding is characterized in that: a coating liquid for forming the chemical conversion coating film contains an acid-modified polyolefin resin, a colloidal silica and a silane coupling agent; the coating amount of the chemical conversion coating film is 0.05-3 g/m2 in terms of dry mass; the adhesive layer contains an acid-modified polyolefin resin; and the adhesive layer has a thickness of 5-100 μm.
