ABSTRACT:
Compositions containing a polymerizable, curable or crosslinkable component, a photoinitiator, a colorformer capable of changing color upon contact with a suitable activator and a latent activator containing an organic halide will become insoluble and change color under the influence of actinic radiation. The organic halide is a carbonylic compound such as an aliphatic or cycloaliphatic ketone or an ester or amide of a dicarboxylic acid. The compositions are useful to make resists used in the electronics industry to manufacture printed circuits.
