ABSTRACT:
Aqueous dispersions comprising water, a cationically curable compound, and a photosensitive onium salt, and preferably other ingredients such as sensitizers, fillers, and plasticizers, are useful for making printing screens, lithographic plates, and printed circuit resists. After exposure, the un-cured composition is easily removed by washing with water.
