Abstract

Photo-crosslinkable polymers are provided and more partic-ularly polymers which can be crosslinked by UV or visible light for use in photoresist compositions and for use in microimaging. The photo-crosslinkable polymers employed are formed from poly(vinylbenzyl chloride) and a light absorbing monomer having at least one carboxy, phenol or an acidic NH group having a pKa of less than about 15. The polymers can be used as photoresists with printed circuits, relief printing or planographic printing and the like. Generally, the light ab-sorbing species is present in a minor amount of less than about 1 percent and contains a single reactive group.
