Abstract

A process is described for producing molding compounds and coatings on substrates by curing radiation-curable compositions under inert gas by exposure to light wherein said inert gas comprises a gas heavier than air, and lateral escape of the inert gas in the course of radiation curing is prevented by means of appropriate apparatus or other measures.
