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 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.
