Abstract

The invention is directed to a process for coating substrates by applying at least one coating composition to an optionally precoated substrate and then curing the coating layer(s) thus obtained, wherein at least one of the coating layers is produced from a coating composition which contains a binder system having olefinic double bonds capable of free-radical polymerization and having reactive functional groups within the meaning of addition and/or condensation reactions, the resin solids of the coating composition having a C&boxH;C-equivalent weight from 300 to 10,000, preferably from 300 to 8,000, and curing of this (these) coating layer(s) is carried out by irradiation with NIR radiation in the wave length range 760-1500 nm.
