ABSTRACT:
A process for producing stable, scratch-resistant coatings comprising the preparation of a photocurable formulation containing certain siloxane photoinitiators as surface-active initiators, application of the formulation to a substrate and the curing of the formulation by exposure to electromagnetic radiation with wavelengths from 200 nm into the IR region and prior, simultaneous or subsequent exposure to heat.
