ABSTRACT:
Multilayer, positive working, thermally imageable, bakeable imageable elements have a substrate, an underlayer, and a top layer. The underlayer comprises a polymeric material that comprises, in polymerized form from about 5 mol % to about 30 mol % of recurring units derived from an ethylenically unsaturated polymerizable monomer having a carboxy group; from about 20 mol % to about 75 mol % of recurring units derived from N-phenylmaleimide, N-cyclohexylmaleimide, N-benzylmaleimide, or a mixture thereof; and from about 3 mol % to about 50 mol % of recurring units derived from a compound represented by the formula:in-line-formulae description="In-line Formulae" end="lead"?CH2═C(R2)—C(O)—NH—CH2—OR1,in-line-formulae description="In-line Formulae" end="tail"?in which R1is C1to C12alkyl, phenyl, C1to C12substituted phenyl, C1to C12aralkyl, or Si(CH3)3; and R2is hydrogen or methyl. Other materials, such as a resin or resins having activated methylol and/or activated alkylated methylol groups, such as a resole resin, may be present in the underlayer. The elements can be used to produce bakeable lithographic printing plates that are resistant to press chemistries.
