The orientation of the radical addition of N-chloroamides (ZCONHCl) to enolethers was studied as a function of Z and the enolether structure and compared with the orientation of radical addition of thioacetic acid and the orientation of typical electrophilicadditions.
N-chloro chloroalkanamides or chloro hydrocarbyl substituted alkanamides of the formula ##STR1## where R.sub.1 is hydrogen or alkyl of 1 to 6 carbon atoms, R.sub.4 is alkylene or chloroalkylene of 1 to 5 carbon atoms, n is 0 or 1, R.sub.2 and R.sub.3 are hydrogen, chlorine, alkyl of 1 to 4 carbon atoms, alkaryl of up to 8 carbon atoms or aryl of up to 8 carbon atoms, have been found useful as herbicides. Preferably n is 0 and R.sub.2 and R.sub.3 are hydrogen chlorine, phenyl or alkyl or 1 to 2 carbon atoms. Most preferably R.sub.2 and R.sub.3 are hydrogen or chlorine.

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.
