摘要： Coated formed materials of plastics or glass having improved anti-scratching and anti-fogging properties, are produced by applying to the surface of the formed material an undercoating material comprising (a) a mixture of methylolmelamine in which all or a part of the methylol groups are alkyletherified, and a polyhydric alcohol having a molecular weight of 1,500 or less which may contain an ethylene oxide or propylene oxide chain, or a pre-condensate thereof, (b) a mixture of a monomer having a unit of the formula (I), ##STR1## wherein R.sub.1 and R.sub.2 are independently a hydrogen atom or a lower alkyl, carboxyl or amino group and X is a hydroxyl group-containing side chain, or a homopolymer or copolymer thereof, and a crosslinking agent, or (c) a mixture of (a) and (b), followed by curing it so that the percentage of residual hydroxyl groups therein is from 60 to 90%, thereby forming a resin film (1), and then topcoating the resin film (1) with a topcoating material comprising a mixture of (d) a mixture of methylolmelamine in which all or a part of the methylol groups are alkyletherified, and a polyhydric alcohol having a molecular weight of 100 to 2,000 and an ethylene oxide chain, or a pre-condensate thereof and (e) a surface active agent, followed by curing it so that the percentage of residual hydroxyl groups therein is from 35 to 70%, thereby forming a melamine resin film (2).
