Abstract

See full text

A process for improving sensitivity of a film base, coated with a dispersion of a normally crystalline polyacetylenic compound in a non-solvating liquid which is dried on the film surface, to particular photon energy band, specifically, long wavelength UV; the polyacetylenic compound preferably having at least two conjugated acetylenic linkages and containing from 12 to 60 carbon atoms. The sensitization of the film to long wavelength UV is achieved via the addition of photoinitiator(s) capable of absorbing UV energy and converting it to free radicals.
