The present invention relates to a medium solid-type coating composition for repairing cars, which has good appearance and low VOC (volatile organic compounds). More particularly, the coating composition comprises a main part and an isocyanate curing agent part. The coating composition uses an acryl polyol resin blend containing an acryl polyol resin having a specifically low glass transition temperature as a resin for the main part, and the main part comprises an exempt solvent. Thus, the coating composition reduces environmental pollution of the conventional oil-soluble top coating film, and thus is eco-friendly and shows excellent coating workability. The coating composition can provide excellent physical properties equivalent to those of a high solid-type coating agent, i.e., coating film appearance (smoothness, gloss and distinctness), drying time, adhesive property, or the like, and thus is particularly suitable for a top coating agent for repairing cars. |
