Metal thin film coating composition

Abstract

Abstract PURPOSE:To provide the title compsn. which can form a topcoat layer having excellent adhesion on the surface of a plastic molding coated with a thin metallic film without using any primer, containing an ultraviolet-curable modified acrylic resin and a reactive alkoxysilane compd. CONSTITUTION:An ultraviolet-curable modified acrylic resin (A) having an acid value of 5-50 [e.g. an epoxyacrylate resin contg. a predetermined amount of an acidic monomer such as bis(acryloxyethyl) phosphate], 0.1-5wt% (based on the amount of component A) reaction alkoxysilane compd. (B) [e.g. N-(2- aminoethyl)-3-aminopropyldimethoxysilane], a tri- or polyfunctional poly(meth) acrylate (C), a sensitizer (D) and additives (E) such as og. solvent, pigment, etc. are blended together.
