ACTIVE ENERGY RAY CURABLE RESIN COMPOSITION, ACTIVE ENERGY RAY CURABLE HARD COATING AGENT, CURED COATING FILM USING IT, AND ARTICLE HAVING CURED COATING FILM

摘要

PPROBLEM TO BE SOLVED: To provide an active energy ray curable resin composition (hard coating agent) capable of forming a cured coating film having high adhesiveness on widely varied materials, in particular, on a metal surface such as a metal-plated surface and metal vapor deposition surface. PSOLUTION: In the active energy ray curable resin composition, a reaction product (A) obtained by performing addition reaction of a carboxyl group-containing (meth)acrylic compound to a polymer obtained by polymerization of a polymer component (a1) containing a vinyl compound having an epoxy group in the molecule, a colloidal silica (B), a specific phosphate compound (C), and a polyfunctional (meth)acrylic compound (D) are included as essential components. A using amount ratio ((A)/(B)) of the reaction product (A) to the colloidal silica (B) is 0.25-1.75, and a (meth)acrylic equivalent of the whole resin composition is 320-550.
