Abstract
(EN)
A topcoating composition and an undercoating composition are provided with which it is possible to provide a multilaylered coating film including a discontinuous metallic thin film and having excellent durability of various kinds. The topcoating composition for discontinuous metallic thin films comprises a hydroxylated resin (A-1), a polyisocyanate compound (B-1), and a silane coupling agent (C-1), wherein the polyisocyanate compound (B-1) includes a nurate of an aliphatic diisocyanate having 4 or 5 carbon atoms. The undercoating composition for discontinuous metallic thin films comprises a hydroxylated resin (A-2), a polyisocyanate compound (B-2), and a silane coupling agent (C-2) and gives a cured coating film having a Tg lower than 80°C.
