Patent ID: 7144661

Claim:
A positive-working imageable element comprising a radiation absorbing compound and a substrate having a hydrophilic surface, and having thereon, in order: an inner layer comprising a polymeric material that is removable using an alkaline developer and in which from about 1 to about 50 mol % of its recurring units are derived from one or more of the ethylenically unsaturated polymerizable monomers represented by the following Structure (I): CH 2 ═C(R 1 )C(═O)NR 2 (CR 3 R 4 ) n OH (I) wherein R 1 , R 2 , R 3 , and R 4 are independently hydrogen, lower alkyl, or phenyl, and n is 1 to 20, and an ink receptive outer layer that is substantially free of said radiation absorbing compound and is not removable by an alkaline developer prior to thermal imaging, provided upon thermal imaging, the imaged regions of said element are removable by an alkaline developer.
