Summary:Improved solid or semisolid photopolymerizable layers for use in producing relief printing plates, said layers including a photopolymerizable compound having at least two polymerizable olefinic double bonds, a photoinitiator, and an indigoid dye, and a process for determining the light sensitivity of said layer by using said indigoid dye as a color indicator whereby the amount of exposure required to photopolymerize the layer by irradiation is accurately determined.
