  • Patent number: 6248502
    Abstract: Flexographic printing plates crosslinkable by photopolymerization are produced by exposing the plates to a light source and washing out (developing) with a solvent the non-crosslinked areas that are masked out during the exposure process. The invention provides terpene ester-based solvents suitable for use in the development of photopolymer printing plates. The solvents, which include terpene esters alone or terpene esters mixed with organic solvents and/or non-solvents, are effective in developing a a large number of different photopolymer printing plates and can produce images superior to those obtained with commercially available solvents currently used in such applications.
