PROCESS FOR PRODUCING LIGHT HARDENED LAYERS WITH A PARTICULAR HARDNESS

Photocured layers possessing a defined controllable hardness are produced by exposing a layer of a photopolymerizable or photocrosslinkable mixture, which contains a partially crystalline polymeric binder possessing olefinic double bonds capable of undergoing polymerization, to actinic light, by a m...

More Information
Summary:Photocured layers possessing a defined controllable hardness are produced by exposing a layer of a photopolymerizable or photocrosslinkable mixture, which contains a partially crystalline polymeric binder possessing olefinic double bonds capable of undergoing polymerization, to actinic light, by a method in which the photocurable layer, prior to exposure to actinic light, is subjected to a heat treatment in which the partially crystalline parts of the polymeric binder are partially or completely fused.
