Abstract
The use of biodegradable polymer films in the manufacture of photosensitive relief image printing plates is described, including printing plates produced from liquid photopolymer resins and from sheet polymers as well as direct write/laser engravable printing plates. The biodegradable polymer films can be used as substrate layers, oxygen barrier layers, and coverfilms and, once the printing plates have been used and disposed of, the biodegradable polymer films are capable of decomposing in the environment.
