Compositions containing a polymerizable, curable or crosslinkable component, a photoinitiator, a fluoran colorformer and a latent activator that releases or promotes the release of a Lewis acid, will become insoluble and change color under the influence of actinic radiation. These compositions are particularly useful to make dry film photoresists, which are widely used in the electronics industry to manufacture printed circuits.
