    摘要： A self-crosslinkable resin useful as, for example, adhesive compositions and coating compositions. The resin contains complementary reactive groups, that is, a blocked isocyanate group and a hydroxyl group, in the same molecule. The resin is prepared by reacting a hydroxy-containing vinyl monomer with some isocyanate groups on the skeleton of a vinyl polymer having at least two isocyanate groups in the molecule so to introduce a polymerizable double bond into the polymer, and subsequently completely blocking the isocyanate group(s) remaining on the polymer skeleton with a blocking agent, or vice versa. Thereafter an unsaturated monomer component consisting essentially of a hydroxyl-containing vinyl monomer is polymerized with the polymerizable double bond introduced.

    摘要： The present invention provides a method for forming a multi-layer coating film by applying a clear coating (B) on the film of a leafing type aluminum flake-containing metallic coating (A), which method comprises forming a film of the metallic coating (A), curing the film, applying thereon a composition (C) containing a polymer formed from an unsaturated monomer having a phosphoric acid group represented by --O--PO(OH)(R.sub.1) (wherein R.sub.1 is a hydroxyl group, a phenyl group or a C.sub.1-20 alkyl group) and a hydroxyl group-containing unsaturated monomer, and then applying the clear coating (B) on the film of the composition (C). The method can form a multi-layer coating film improved in interlayer adhesivity between the metallic coating film and the clear coating film, without reducing the excellent effects and metallic feeling provided by a metallic coating film containing leafing type aluminum flake.
