  • Publication number: 20040152019
    Abstract: This invention describes photopolymer printing plate developing solvents comprising diisopropylbenzene, alone or in combination with one or more co-solvents. Compared with solvents of the prior art, the developing solvents of the present invention have lower toxicity, higher flash points, a milder and more pleasant odor, increased resistance to thermal decomposition, higher solvency, faster dry time, and pose reduced threat to the environment. The solvents of the present invention can exhibit azeotropic-like properties resulting in improved recycling characteristics and reduced drying times. Also, the solvents of the present invention exhibit a degree of selective solvency towards non-crosslinked photopolymers vs. crosslinked photopolymers that is not seen in solvents of the prior art.
