ABSTRACT:
Most color proofing constructions use photooligomers that are tacky, require an oxygen barrier to protect the colorant layer and have a short shelf life. The use of alkali soluble photopolymers in the colorant layer of a color proofing construction provides a more easily processable proofing construction, eliminates the need for an oxygen barrier and has improved shelf life of the photopolymer. The proofing construction has a flexible support base film and a colorant layer coated thereon, wherein the colorant layer comprises a colorant and an alkali soluble photopolymer.
