Claim 1

A PRINT-OUT MEMBER CONSISTING OF A SUPPORT AND A DRY FILM DEPOSITED THEREON SAID FILM CONSISTING OF (1) A FILM-FORMING MATERIAL SELECTED FROM THE GROUP CONSISTING OF FILM FORMING CELLULOSE DERIVATIVES AND POLYMERS OF VINYLIDENE MONOMERS WHICH CONTAIN OXYGEN AND HYDROGEN IN THEIR MOLECULE; (2) AN ACID-BASE TYPE INDICATOR SELECTED FROM THE GROUP OF COMPLEX ORGANIC COMPOUNDS WHICH ARE SOLUBLE IN WATER AND WATER-MISCIBLE COMPOUNDS AND WHICH YIELD A DISTINCTIVE COLOR CHANGE OVER A NARROW RANGE OF PH IN THE PRESENCE OF AT LEAST A TRACE OF WATER; AND (3) AT LEAST ONE HALOGEN CONTAINING ORGANIC COMPOUND REACTIVE WITH SAID INDICATOR UNDER THE INFLUENCE OF ILLIMINATION, TO PRODUCE A CHANGE IN THE COLOR OF THE FILM DIRECTLY AND SOLELY AS A RESULT OF SAID EXPOSURE TO LIGHT, THERE BEING BETWEEN 0.5 AND 2 PARTS OF HALOGEN CONTAINING COMPOUND FOR EACH PART BY WEIGHT OF FILM-FORMING MATERIAL AND BETWEEN 0.02 AND ABOUT 0.40 PART BY WEIGHT OF ACID-BASE TYPE INDICATOR FOR EACH PART BY WEIGHT OF THE TOTAL OF ORGANIC HALOGEN CONTAINING COMPOUND AND FILM-FORMING MATERIAL.

Claim 3

A METHOD OF PRINTING OUT COLORED IMAGES DIRECTLY AS A RESULT OF EXPOSING A PHOTOSENSITIVE COMPOSITION TO LIGHT OF A SUITABLE WAVELENGTH, WHICH METHOD COMPRISES: PREPARING A DRY PHOTOGRAPHIC FILM CONSISTING ESSENTIALLY OF (1) A FILM-FORMING PLASTIC SELECTED FROM THE GROUP CONSISTING OF FILM-FORMING PLASTICS WHICH CONTAIN OXYGEN AND HYDROGEN IN THEIR MOLECULE; (2) AN ACID-BASE TYPE INDICATOR SELECTED FROM THE GROUP OF COMPLEX ORGANIC COMPOUNDS WHICH ARE SOLUBLE IN WATER AND WATER-MISCIBLE COMPOUNDS AND WHICH YIELD A DISTINCTIVE COLOR CHANGE OVER A NARROW RANGE OF PH IN THE PRESENCE OF AT LEAST A TRACE OF WATER; AND (3) A HALOGEN-CONTAINING COMPOUND SELECTED FROM THE GROUP CONSISTING OF CARBON TETRABROMIDE, IODOFORM, BROMOFORM, CHLOROFORM, CARBON TETRACHLORIDE, TETRABROMBUTANE, HEXACHLORETHANE, TETRACHLORTETRAHYDRONAPHTHALENE, DICHLORBENZENE, DIBROMBENZNEN AND HEXACHLORBENZENE, EACH OF WHICH IS A HALOGEN CONTAINING COMPOUND WHICH ON EXPOSURE TO LIGHT OF A SUITABLE WAVELENGTH DECOMPOSES TO YIELD FREE RADICALS CONTAINING A HALOGEN SELECTED FROM THE GROUP CONSISTING OF C1, BR, AND I; SAID ACIDBASE INDICATOR AND SAID HALOGEN CONTAINING COMPOUND BEING DISPERSED THROUGHOUT SAID FILM-FORMING PLASTIC MATERIAL, THERE BEING BETWEEN ABOUT 0.5 AND 2 PARTS OF SAID HALOGEN CONTAINING COMPOUND FOR EACH PART BY WEIGHT OF SAID FILM-FORMING PLASTIC MATERIAL AND BETWEEN ABOUT 0.02 AND 0.40 PART BY WEIGHT OF SAID ACID-BASE INDICATOR FOR EACH PART OF THE TOTAL OF ORGANIC HALOGEN COMPOUND AND FILM-FORMING PLASTIC IN SAID FILM; AND EXPOSING SELECTED PORTIONS OF SAID FILM TO A SOURCE OF LIGHT HAVING A WAVELENGTH BETWEN ABOUT 2500 A. AND 4000 A., WHEREBY A REACTION OCCURS PRODUCING A VISIBLE COLOR CHANGE IN THE FILM DIRECTLY AND SOLELY AS A RESULT OF SAID EXPOSURE.

Claim 4

A METHOD OF PRINTING OUT COLORED IMAGES DIRECTLY AS A RESULT OF EXPOSING A PHOTOSENSITIVE COMPOSITION TO LIGHT OF A SUITABLE WAVELENGTH, WHICH METHOD COMPRISES: PREPARING A DRY PHOTOGRAPHIC FILM CONSISTING ESSENTIALLY OF (1) A FILM-FORMING PLASTIC SELECTED FROM THE GROUP CONSISTING OF FILM-FORMING PLASTICS WHICH CONTAIN OXYGEN AND HYDROGEN IN THEIR MOLECULE; (2) AN ACID-BASE TYPE INDICATOR SELECTED FROM THE GROUP OF COMPLEX ORGANIC COMPOUNDS WHICH ARE SOLUBLE IN WATER AND WATER-MISCIBLE COMPOUNDS AND WHICH YIELD A DISTINCTIVE COLOR CHANGE OVER A NARROW RANGE OF PH IN THE PRESENCE OF AT LEAST A TRACE OF WATER; AND (3) A HALOGEN-CONTAINING COMPOUND SELECTED FROM THE GROUP CONSISTING OF CARBON TETRABROMIDE, IODOFORM, BROMOFORM, CHLOROFORM, CARBON TETRACHLORIDE, TETRABROMBUTANE, HEXACHLORETHANE, TETRACHLORTETRAHYDRONAPHTHALENE, DICHLORBENZENE, DIBROMBENZNEN AND HEXACHLORBENZENE, EACH OF WHICH IS A HALOGEN CONTAINING COMPOUND WHICH ON EXPOSURE TO LIGHT OF A SUITABLE WAVELENGTH DECOMPOSES TO YIELD FREE RADICALS CONTAINING A HALOGEN SELECTED FROM THE GROUP CONSISTING OF C1, BR, AND I; SAID ACIDBASE INDICATOR AND SAID HALOGEN CONTAINING COMPOUND BEING DISPERSED THROUGHOUT SAID FILM-FORMING PLASTIC MATERIAL, THERE BEING BETWEEN ABOUT 0.5 AND 2 PARTS OF SAID HALOGEN CONTAINING COMPOUND FOR EACH PART BY WEIGHT OF SAID FILM-FORMING PLASTIC MATERIAL AND BETWEEN ABOUT 0.02 AND 0.40 PART BY WEIGHT OF SAID ACID-BASE INDICATOR FOR EACH PART OF THE TOTAL OF ORGANIC HALOGEN COMPOUND AND FILM-FORMING PLASTIC IN SAID FILM; AND EXPOSING SELECTED PORTIONS OF SAID FILM TO A SOURCE OF LIGHT HAVING A WAVELENGTH BETWEN ABOUT 2500 A. AND 4000 A., WHEREBY A REACTION OCCURS PRODUCING A VISIBLE COLOR CHANGE IN THE FILM DIRECTLY AND SOLELY AS A RESULT OF SAID EXPOSURE.
