ABSTRACT:
The invention relates to a multilayered image receptive film capable of being developed in distinguishable colors by kinetic energy imparted by radiant beam exposure which comprises (a) a first imaging layer composed of an aliphatic, polymeric binder containing from about 40 wt. % to about 70 wt. % of labile halogen, said binder capable of dehydrohalogenation at address points of radiant energy exposure and having dispersed therein a leuco base polyphenylmethane compound capable of forming a halide salt dye as a first color upon generation of hydrogen halide from said binder; (b) a separate imaging layer composed of a base film containing a photosensitive polyacetylenic compound having at least two acetylenic linkages in a conjugated system and contiguously disposed below said first imaging layer capable of forming a dye of a color distinguishable from that of said halide salt dye and (c) a conductive support for layers (a) and (b).
The invention also relates to a process of multi-color imaging by subjecting said film to a plurality of radiant energy exposures at critically distinct beam energies and exposure dosages individually modulated in accordance with the sensitivity of the dye developing compound in each imaging layer to form dyes of distinguishable colors in each of said imaging layers at the respective points of beam address.
