Production of urethane group containing coatings by curing with ionizing radiation

摘要

The present invention relates to a process for the manufacture of coatings by applying ionizing radiation to a composition which contains olefinically unsaturated polymeric materials having urethane groups and has been applied to a substrate. The polymeric materials, which may be used in combination with olefinically unsaturated monomeric compounds and conventional additives, contain, in the same molecule, at least two units of the general formula AND/OR WHERE R is hydrogen or methyl.
