An aqueous-developable article is made from a photosensitive prepolymer made by reacting together (a) maleated alkadiene polymer or copolymer, (b) hydroxyalkyl(meth)acrylate or hydroxy(polycaprolactone)acrylate, (c) polybutadiene diol or polyisoprene diol, and (d) monohydroxy-terminated thermoplastic polymer, such as monohydroxy-terminated or monohydroxy-terminated followed by hydrolysis and at least partial neutralization by reaction with a base, e.g. NaOH, to form an ionomer. When formulated with photoinatiator and (optional) unsaturated monomers, the ionomer is particularly useful in making photopolymer-based flexographic printing plates.
