ONE COMPONENT LOW BAKE PAINT COMPOSITION AND ACRYLIC POLYOL RESIN COMPOSITION

摘要

The present invention relates to an acryl polyol resin composition and a paint composition ensuring low-temperature stoving comprising same. More specifically, the present invention relates to an acryl polyol resin which has glass transition temperature within a certain temperature range and flexibility to its resin skeleton. To this end, applied thereto is an oligomer in which a repeating structure represented by -CH_2- is formed in the skeleton of the resin, by creating a lactone-derived an aliphatic linear structure to a hydroxyl group-containing acryl monomer via lactone modification. The present invention further relates to a paint composition which secures the same level of material properties with a conventional paint composition even after curing by low-temperature stoving process, by improving reactivity and lowering the glass transition temperature due to containing the acryl polyol resin.
