Novel compositions comprising photoactive polymers comprising a dinitrobenzyl group in conjunction with a photoacid generator are disclosed. In one embodiment, the photoacid generator is a diazide and/or a sulfonyl aceto carbonyl compound. The photoacid generators are typically used in amounts of 10 weight percent or less. The compositions find particular application in storage stable, pH stable, and water stable positive photoresist compositions. Such compositions demonstrate reduced process time as compared with similar compositions lacking the photoacid generator. Methods for using these compositions are also disclosed.
