COMPOSITION FOR METAL SURFACE TREATMENT, SURFACE TREATMENT METHOD FOR ALUMINUM-BASED METAL BASE MATERIAL BY USING THE COMPOSITION, AND SURFACE-TREATED ALUMINUM-BASED METAL BASE MATERIAL MANUFACTURED BY USING THE METHOD

摘要

PPROBLEM TO BE SOLVED: To provide a composition for metal surface treatment with which the sufficient tight adhesion between a laminated film or a coating film to be formed from various kinds of paint and an aluminum-based metal base material can be ensured and which does not contain a fluorine ion, a chromium ion and an organic solvent and imposes little load on the environment. PSOLUTION: The composition for the metal surface treatment for use in surface treatment of the aluminum-based metal base material is provided which contains a basic zirconium compound and/or a cerium compound, a carboxyl group-containing resin and an oxazoline group-containing acrylic resin but does not contain fluorine.
