| abstract |
The process of this invention applies at least one coating composition to an optionally precoated substrate and then cures the thus obtained coating layer(s), whereby at least one of the coating layers is prepared from a coating composition that can be chemically cross-linked solely by radical polymerization of olefinic double bonds, the resin solid of the composition has a C=C equivalent weight from 100 to 10,000, preferably from 100 to 5,000, and the curing of the coating layer(s) is carried out with NIR radiation in the wave length range from 760-1500 nm. |
