A polycarbonate resin shaped article having a cured coating of a melamine-type resin on its surface through a primer layer resulting from the solidification or curing, in the presence or absence of a crosslinking agent and a crosslinking catalyst, of a primer comprising(A) a polymer containing at least 5 mole% of a recurring structural unit of the formula ##STR20## wherein R1 and R2, independently from each other, represent a hydrogen atom or a lower alkyl or carboxyl group, and X represents a side chain containing a carboxyl or carbamoyl group, or(B) a polymer containing at least 2.5 mole% each of a recurring structural unit of the formula ##STR21## wherein R1 and R2 are the same as defined above and Y represents a hydroxyl-containing side chain,and a recurring structural unit of the formula ##STR22## wherein R3 and R4, independently from each other, represent a hydrogen atom or a lower alkyl or carboxyl group, and Z represents a side chain containing a carboxyl group, an amino group, a substituted amino group, an epoxy group or a tetrahydrofuryl group.
