ABSTRACT:
A process for recycling exposed and/or unexposed photopolymer flexographic printing plate containing a photopolymerizable recording layer and a support, said process comprising (a) separating the recording layer from the support and comminuting the material and (b) adding the material to a photopolymer mixture is described. The process reduces waste problems, is more environmentally friendly and is used to prepare photopolymerizable flexographic printing plates containing less raw materials.
