Abstract
Disclosed herein are monomeric compounds having the formula (I): ##STR1## wherein: R, R.sup.1, R.sup.2 and R.sup.3 are independently hydrogen or alkyl having from 1 to 4 carbon atoms; R.sup.4 is arylene having 6 to 18 carbon atoms; m is an integer from 1 to 4; and n is an integer from 0 to 4. These monomers can be homopolymerized or copolymerized with one or more other polymerizable monomers, and can particularly be copolymerized with those monomers having substituents which are susceptible to attack or degradation by a base. The resulting crosslinkable polymers are useful in relief image materials, such as photoresists and lithographic plates.
