Abstract
A paint composition suitable for hydraulic transfer painting of automotive parts is provided. The painting composition includes urethane beads, thereby imparting a good touch sensation to a painted surface and improving the durability of the painted automotive part. The paining composition includes a resin mixture containing an acrylic polyol resin and a polyester polyol resin, a solvent, an anti-sedimentation agent, a curing accelerator, a UV stabilizer, a polysiloxane-based surface conditioning agent, a wax, and a urethane bead.
