Abstract:
A method for forming an image, the method comprising the steps of:(A) providing an imagewise exposed imageable element, in which: the imageable element comprises a radiation-sensitive layer over a support, the radiation-sensitive layer comprises a radiation-sensitive initiator system and at least one free radical polymerizable material, and the radiation-sensitive layer comprises exposed regions and unexposed regions; (B) applying a developer to the imagewise exposed imageable element, removing the unexposed regions of the imageable element, and forming the image, in which: the developer has a pH of about 5.0 to about 12.0, the developer comprises: water, a buffer, and a component selected from the group consisting of (a) an added filter dye or mixture of filter dyes, and (b) an added free radical inhibitor or mixture of free radical inhibitors, the absorption of the filter dye is matched to the absorption of the radiation-sensitive initiator system, and the free radical inhibitor is a material capable of reacting with free radicals to form products that do not initiate polymerization of the free radical polymerizable material.
