Abstract
The present invention discloses stabilizers for formulations containing photoacid precursors and cationically polymerizable materials. The stabilizers have a limited solubility in the formulations and are in solubility equilibrium in the formulation. The stabilizers being present as a solid phase in the formulation in excess of their solubility limit, the concentration of the stabilizers is continuously replenished as the stabilizer reacts with undesired free acid.
