The present invention relates to a UV curable paint composition which is coated on chrome plated surfaces used as a vehicle radiator grill, and vehicle sub materials and parts and, more specifically, to a paint composition prepared by UV curing under coat (primer) and top coat and room temperature setting the same. The dual curable paint composition coated on the chrome plated surface is environment-friendly paint developed for reducing VOC, and is divided into a under coat composition and a top coat composition. The under coat composition: uses an unsaturated polyester polyol resin having 0.1-2.0% of hydroxyl group, 2000-5000 of number-average molecular weight, and 20-80% of reactive monomer diluent as a resin for main material; and uses the reactive monomer diluent when making the paint in order to give adhesive property and chipping resistance to the chrome plated surface. The top coat composition: uses a resin selected from a group including acrylate oligomer, unsaturated polyester polyol resin having 1.5-5.0% of hydroxyl group, 1000-15000 of number-average molecular weight, and 20-70% of the reactive monomer diluent, and a mixture thereof; and uses the reactive monomer diluent when making the paint in order to give film hardness, water resistance, and alkali resistance by being coated on the under coat composition. |
