The invention provides a negative-acting photoimageable composition comprising A) between about 30 and about 80 wt% based on total weight of A) plus B) of a binder polymer having acid functionality sufficient to render said photoimageable composition developable in alkaline aqueous solution, B) between about 20 and about 70 wt% based on total weight of A) plus B) of an addition-polymerizeable, non-gaseous .alpha.,.beta.- ethylenically unsaturated compound(s) capable of forming a high polymer by free-radical initiated chain- propagating addition polymerization, at least about 50 mole percent of the .alpha.,.beta.- ethylenically unsaturated moieties of B) being methacrylic moieties, and C) between about 0.1 and about 20 wt% based on total weigh of A) plus B) of a photoinitiator chemical system. Photopolymerizable component B comprises, at between about 1 and about 70 wt.% relative to total of A) plus B) a biuret urethane oligomer having .alpha.,.beta.-ethylenic unsaturation.
