Abstract
A process for producing scratch-resistant coatings, encompassing the following steps: applying at least one UV-curable coating composition to at least one surface of an article to be coated, said coating composition comprising at least one polymer and/or oligomer P1 containing on average at least one ethylenically unsaturated double bond per molecule, and curing the coating composition by exposure to UV radiation, which comprises conducting the curing of the coating composition under an oxygen-containing protective gas which has an oxygen partial pressure in the range from 0.2 to 18 kPa.

A process for producing a scratch-resistant coating, said process comprising:
- applying at least one UV-curable coating composition to at least one surface of an article to be coated, said coating composition comprising at least one polymer and/or oligomer P1 containing an average of at least one ethylenically unsaturated double bond per molecule, and
- curing said coating composition by exposure to UV radiation under an oxygen-containing protective gas which has an oxygen partial pressure in the range of from 0.5 to 18 kPa.
