Abstract
Acetylenic compounds such as 2,6-hexadiyn-1,6-diol-bis(p-phenylazophenylsulfonate) having a conjugated acetylenic portion capable of polymerization on exposure to actinic radiation and thermal annealing and a chromophoric portion. The color of the chromophoric portion provides a background for distinguishing color variations in the initial polymerization of conjugated acetylenic moieties.
