MULTILAYER IMAGEABLE ELEMENT WITH IMPROVED CHEMICAL RESISTANCE

摘要

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): <?in-line-formulae description="In-line Formulae" end="lead"?>CH<SUB>2</SUB>-C(R<SUP>1</SUP>)C(-O)NR<SUP>2</SUP>(CR<SUP>3</SUP>R<SUP>4</SUP>)<SUB>n</SUB>OH (I)<?in-line-formulae description="In-line Formulae" end="tail"?> wherein R<SUP>1</SUP>, R<SUP>2</SUP>, R<SUP>3</SUP>, and R<SUP>4 </SUP>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.
