PROBLEM TO BE SOLVED: To provide a coating composition and a coated metal plate preventing deteriorations such as a damage and a corrosion of the coated film and exhibiting excellent scratch resistance. SOLUTION: This coating composition is characterized by comprising a resin composition composed of (a) an oligomer having a composition represented by general formula (1) [wherein, n is an integer of 2-10; R is -(CH2)m-; m is an integer of 1-10; and R' is a group represented by general formula (2)] in an amount of 1-10 wt.% based on the weight of the resinous solid content, (b) one ore more kinds of a polyester resin, an acrylic resin and an epoxy resin in an amount of 40-95 wt.% based on the weight of the resinous solid content and (c) an amino resin and/or a polyisocyanate resin which is a curing agent. The coated metal plate is obtained by coating the surface of a metal plate with the coating composition to form a coated film having >=10μm thickness. |
