Title:

WATER−BASED COATING COMPOSITION CURABLE WITH ACTINIC ENERGY RAY, COATED METALLIC MATERIAL, AND PROCESS FOR PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/2003/008507

Kind Code:

A1

Abstract:

An excellent water−based coating composition curable with actinic energy rays which is highly safe and combines adhesion to metal surfaces and corrosion resistance, which have been considered to be inconsistent with each other, in particular adhesion after severe processing and resistance to solvents, especially alcohols having high polarity. The composition comprises (1) a phosphoric ester compound having an ethylenically unsaturated double bond, (2) a water−compatible polyurethane resin having both an ethylenically unsaturated double bond and a group capable of forming a salt, and (3) colloidal silica.
