A painted article includes a primer layer between a substrate and a paint layer, of which the substrate is the product of a substrate forming composition including an olefin block copolymer and a polypropylene polymer having a density from 0.89 g/cm3 and 0.92 g/cm3. The substrate is free of (1) phthalate-based plasticizer, (2) halogen-containing polymer, and (3) leachable, small polymeric units derived from styrene monomer.
