Photosensitive image forming composition containing at least one substituted bis-diaryl vinylidene compound and/or at least one substituted bis-diaryl imine compound
 A non-silver photosensitive image forming composition containing at least one substituted bis-diaryl vinylidene compound and/or at least one substituted bis-diaryl imine compound and tetraiodoethylene in a dried photosensitive layer thickness not exceeding 3 microns in layer thickness, the nature of the substitution being such that substantially any high extinction absorption peak or combination of high extinction absorption peaks is available from a family of compositions covering the range of 350 to 900 nm in wavelength, said composition being placed on a transparent or reflective substrate fitted with a compatible adhesive for the photosensitive layer not more than 0.5 micron in thickness and containing specialized stabilizers to permit precision information to be read out by a focused laser beam in either the transmissive or reflective mode, said precision information being placed on the film by exposure to precision light patterns followed by development and fixing with solvents and/or with heat not exceeding 115.degree.
