Abstract
There are disclosed light-sensitive compounds and a composition comprising (a) such compounds and (b) a compound having at least one reactive site capable of stepwise photo-reaction with the light-sensitive compounds. The light-sensitive compounds have the structural formula, ##STR1## wherein Z.sup.1 and Z.sup.2 are each independently the number of non-metallic atoms necessary to complete 1, 2, 3, or 4 unsaturated carbocyclic or heterocyclic rings of from 6 to 18 nuclear atoms; PA1 Z.sup.3 is either a carbon-to-carbon bond or vinylene; PA1 and X is a linking group. The composition can be applied to a variety of supports and photoreacted by exposure to activating radiation.
