Title:
ADHESIVE COMPOSITION, METHOD FOR PRODUCING SURFACE-TREATED METAL MEMBER, AND METHOD FOR PRODUCING METAL-RESIN COMPOSITE BODY
Document Type and Number:
WIPO Patent Application WO/2020/170638
Kind Code:
A1
Abstract:
An adhesive composition for forming an adhesive layer on the surface of a metal for adhesion with a resin that is a thermosetting resin. This composition is an aqueous solution which contains a low-molecular-weight organic compound that has two or more nitrogen atoms in each molecule and one or more kinds of metal ions that are selected from the group consisting of trivalent aluminum ions and trivalent chromium ions, and which has a pH of 12 or less; the concentration of the low-molecular-weight organic compound is 0.01-150 g/L; and the molar concentration of the metal ions is 0.005-100 mmol/L. This adhesive composition is able to improve adhesion between a resin and the surfaces of a plurality of metals.
