Water-based fixing agents for non-chlorine, non-volatile organic compounds for polyolefin based substrates

摘要

The present invention relates to a process for the preparation of a copolymer comprising a non-halogen propylene / alpha-olefin copolymer, wherein the copolymer has an alpha, beta -unsaturated dicarboxylic acid or anhydride grafted thereon, a base, The present invention relates to an aqueous coating composition of a non-volatile organic compound comprising an acidic resin, wherein the composition is applied to a plastic substrate comprising a propylene polymer and the dried coating enhances adhesion of the subsequent coating to the polypropylene surface of the article .
