| abstract |
The invention relates to one or more photoacid generators, one or more organic acid anhydride monomers or polymers, one or more epoxies, one or more nitrogen-containing curing catalysts, and any aromatic hydroxyl-containing monomers, capable of generating an acid upon exposure to actinic radiation, It relates to a positive action photoimaging composition comprising a polymer or mixtures thereof. The photographic element has the composition coated and dried on a substrate. The positive working phase is formed by exposing the element to the actinic phase to form a phase, optionally postbaking and developing with a liquid developer. |
