Abstract: Imageable elements that contain copolymers soluble in alkaline solutions are disclosed and methods for forming imaging using the imageable elements are disclosed. The alkali soluble copolymers comprise about 3 to about 50 mol % of one or more of the monomers of the formula: CH2═CH(R1)—C(O)—X—Y—R2; in which: R1 is H or CH3; R2 is succinimide or phthalimide; X is O or NH; and Y is —(CH2)n—, in which n is an integer from 2 to 12. The imageable elements are useful as lithographic printing plate precursors.

Abstract: A positive-working imageable element comprises inner and outer layers and a radiation absorbing compound such as an IR absorbing dye. The inner layer includes a polymeric material that is removable using an alkaline developer. An ink receptive outer layer is not removable using an alkaline developer before its exposure to imaging radiation. The outer layer includes a polymer binder having pendant epoxy groups that are substantially unreacted during exposure.

Abstract: Positive-working imageable elements comprise a radiation absorbing compound and inner and outer layers on a substrate having a hydrophilic surface. The inner layer comprises a polymer 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): CH2═C(R1)C(═O)NR2(CR3R4)nOH   (I) wherein R1, R2, R3, and R4 are independently hydrogen, lower alkyl, or phenyl, and n is 1 to 20. The imageable elements having improved resistance to development and printing chemicals and solvents.
