Method for manufacturing active energy line-curing primer coating composition and coated articles suitable for automotive lamp reflector components to which metallic mirror finishes are to be applied.

Abstract

The object of this invention is to provide an active energy line-curing primer composition suitable for automotive lamp reflectors to which a metallic mirror finish will be applied, and an automotive lamp reflector to which a metallic mirror finish will be applied, formed by applying the primer composition. The aforementioned active energy line-curing primer composition suitable for automotive lamp reflectors to which a metallic mirror finish will be applied possesses curing properties achieved by a light source generating device from an active energy line from a light-emitting diode. The active energy line-curing primer composition suitable for automotive lamp reflectors to which a metallic mirror finish will be applied according to this invention is characterized by comprising: a predetermined alkyd resin; a predetermined mixture of dinepentylenetetrol hexa(meth)acrylate and dinepentylenetetrol penta(meth)acrylate; a 2- to 3-functional (meth)acrylate having an intramolecular cyclic structure; a hydrogen-abstracting photopolymerization initiator; an α-aminoalkylbenzophenone-based photopolymerization initiator; an amine synergist; and an organic solvent, in predetermined amounts.
