Process for the production of photostructured layers with improved mechanical properties
Abstract
The invention relates to a method for producing photostructured layers or three-dimensional objects. Through the use of photosensitive blends with a thermally fusible polymer / plasticizer dispersion, at least one monomer, a photoinitiator and a thermally reactive compound, which are both imagewise photopolymerized and thermally fused and thermally polymerized, structured materials can be prepared which incorporate have higher mechanical strength.
