PURPOSE: A composition for undercoating a plastic article, and a 2-liquid type paint composite including thereof are provided to offer the cold and heat resistance, and the low temperature hardening property of the composition. CONSTITUTION: A composition for undercoating a plastic article contains a (meth)acrylic copolymer resin, an acrylate based multi-functional monomer, and an organic solvent. The (meth)acrylic copolymer resin has the average molecular weight of 5,000~30,000, the glass transition temperature of 40~70deg C, and the acid value of 2~30mg KOH/g. The 2-liquid type paint composite contains the composition as a base material, and a hardener composition with an initiator and a silane coupling agent. |
