Abstract
An edge-covering composition for covering the cut surfaces of a photosensitive printing element to prevent premature curing of the cut surfaces during a process of manufacturing the printing element. The edge-covering composition is an emulsion comprising one or more emulsifiers, one or more-ultraviolet radiation-absorbing materials, optionally, a coloring agent, and optionally, one or more additional additives. The emulsion compositions are easy to apply, non-toxic, inexpensive, and are largely compatible with the solvents used to wash uncured photopolymer from the printing elements during processing.
