Abstract
Film-forming coating composition for application to a polypropylene substrate, which comprises a polypropylene-adherable polymer P which has a polymer backbone having pendant and/or terminal groups which comprise a moiety of formulae ##STR1## where n is 2 to 500; R.sup.1 is alkyl of 1 to 3 carbon atoms, R.sup.2 is H or an alkyl or alkenyl group of 1 to 3 carbons, and X is H or halogen and Y is H or halogen. Typically R.sup.1 is methyl, R.sup.2 is H, and X and Y are H. The composition optionally includes a filmogenic polymer Q, different to P.
