<p>A negative-working radiation-sensitive composition includes a polymeric binder comprising a polymer backbone and having attached thereto a carbazole derivative represented by the following Structure (I): wherein Y is a direct bond or a linking group, and R<SUP>1 </SUP>to R<SUP>8 </SUP>are independently hydrogen, or an alkyl, alkenyl, aryl, halo, cyano, alkoxy, acyl, acyloxy, or carboxylate groups, or any adjacent R<SUP>1 </SUP>through R<SUP>8 </SUP>groups can together form a carbocyclic or heterocyclic group or a fused aromatic ring. The composition can be sensitive to radiation having a maximum wavelength of from about 150 to about 1500 nm, and can be used to prepare negative-working imageable elements that be imaged and developed as lithographic printing plates.</p> |
