ABSTRACT:
A multi-layer coating comprising a base coat and a topcoat is formed on an article such as a chemically-treated steel plate by coating the article with a base coat composition containing (a) a cross-linking agent which does not interfere with the hydrosilylation reaction of a topcoat composition, and (b) a functional resin reactable with the cross-linking agent, and then with a topcoat composition containing (c) (i) a blend of a hydrosilyl group-containing compound and an alkenyl group-containing compound, and/or (ii) a self-crosslinkable resin, and (d) a catalytic amount of a hydrosilylation catalyst, followed by separate or simultaneous baking. The topcoat composition may contain functional groups (phosphoric groups and/or alkoxysilyl groups) or a functional group-containing compound.
