Claim 1

THE METHOD OF FORMING A COLORED PICTURE FILM COMPRISING SENSITIZING A FILM OF POLYVINYL ALCOHOL WITH A SOLUTION COMPRISING APPROXIMATELY 250 CC. OF WATER, APPROXIMATELY 5 TO 30 GRAMS OF NAPHTHANIL DIAZO BLUE B SALTS, AND APPROXIMATELY 10 TO 70 GRAMS OF SODIUM PHOSPHATE MONOBASIC TO FORM WITHIN SAID FILM A SENSITIZER OF A DYEFORMING TYPE, EXPOSING SAID SENSITIZED FILM TO ULTRA-VIOLET LIGHT THROUGH A CYAN MASTER COLOR SEPARATION POSITIVE, FOR CAUSING DECOMPOSITION OF SAID SENSITIZER IN ACCORDANCE WITH THE VARYING OPACITY OF SAID CYAN MASTER COLOR SEPARATION POSITIVE, SUBJECTING SAID EXPOSED FILM TO A CYAN COUPLING SOLUTION COMPRISING APPROXIMATELY 200 CC. OF A FIRST STOCK SLOUTION EMBODYING APPROXIMATELY 500 CC. OF SODIUM CHLORIDE AND APPROXIMATELY 1500 CC. OF WATER HAVING ADDED THERETO APPROXIMATELY 30 TO 70 CC. OF A SECOND STOCK SOLUTION EMBODYING APPROXIMATELY 7 TO 14 GRAMS OF POTASSIUM HYDROXIDE AND APPROXIMATELY 400 CC. OF SAID FIRST STOCK SOLUTION AND FURTHER HAVING ADDED THERETO APPROXIMATELY 3 TO 10 GRAMS OF 1 AMINO 8-NAPHTHOL 2,4-DISULFONIC ACID FOR A TIME INTERVAL SUFFICIENT TO PERMIT SAID CYAN COUPLING SOLUTION TO REACT WITH THE UNDECOMPOSED DYEFORMING SENSITIZER IN SAID FILM TO PRODUCE AN IMAGE OF A CYAN COLOR, TREATING SAID FILM WITH A NEUTRALIZING SOLUTION COMPRISING APPROXIMATELY 250 CC. OF SAID FIRST STOCK SOLUTION HAVING APPROXIMATELY 3 TO 30 GRAMS OF CUPRIC CHLORIDE ADDED THERETO FOR STOPPING ACTION OF SAID CYAN COUPLING SOLUTION AND TO CAUSE THE CYAN COLOR TO ASSUME THE DESIRED SHAPE AND DENSITY, RESENSITIZING SAID FILM WITH MORE OF SAID WATER SOLUTIN OF DIAZO SALTS, AND SODIUM PHOSPHATE MONOBASIC, EXPOSING THE RESENSITIZED FILM TO ULTRA-VOILET LIGHT THROUGH A YELLOW MASTER COLOR SEPERATION POSITIVE FOR DECOMPOSING SAID SENSITIZER IN ACCORDANCE WITH THE VARYING OPACITY OF SAID YELLOW MASTER COLOR SEPARATION POSITIVE, SUBJECTING SAID EXPOSED FILM TO A YELLOW COUPLING SOLUTION COMPRISING APPROXIMATELY 200 CC. OF SAID FIRST STOCK SOLUTION, APPROXIMATELY 50 CC. OF SAID SECOND STOCK SOLUTION, AND APPROXIMATELY 1/2 TO 2 CC. OF PHENOL SOLUTION TO REACT WITH THE UNDECOMPOSED SENSITIZER IN SAID FILM TO PRODUCE AN IMAGE ACCORDING TO SAID YELLOW MASTER COLOR SEPARATION POSITIVE, NEUTRALIZING THE FILM IN MORE OF SAID MENTIONED NEUTRALIZING SOLUTION FOR PRODUCING THE DESIRED YELLOW SHADE AND DENSITY, RESENSITIZING SAID FILM WITH MORE OF SAID WATER SOLUTION OF DIAZO SALT AND SODIUM PHOSPHATE MONOBASIC, EXPOSING THE RESENSITIZED FILM TO ULTRA-VOILET LIGHT THROUGH A MAGENTA MASTER COLOR SEPARATION POSITIVE FOR DECOMPOSING SAID SENSITIZER IN ACCORDANCE WITH THE VARYING OPACITY OF SAID MAGENTA MASTER COLOR SEPARATION POSITIVE, SUBJECTING SAID EXPOSED FILM TO A MAGENTA COUPLING SOLUTION COMPRISING APPROXIMATELY 225 CC. OF SAID FIRST STOCK SOLUTION, APPROXIMATELY 15 TO 50 CC. OF SAID SECOND STOCK SOLUTION AND APPROXIMATELY 5 TO 20 CC. OF ALCOHOL HAVING DISSOLVED THEREIN APPROXIMATELY .3 TO .5 CC. OF M-AMINOPHENOL FOR A TIME INTERVAL SUFFICIENT TO PERMIT SAID MAGNETA COUPLING SOLUTION TO REACT WITH THE UNDECOMPOSED SENSITIZER IN SAID FILM TO PRODUCE AN IMAGE OF A MAGENTA COLOR ACCORDING TO SAID MAGENTA MASTER COLOR SEPARATION POSITIVE, AND NEUTRALIZING THE FILM IN MORE OF SAID NEUTRALIZING SOLUTION FOR CAUSING TH MAGENTA COLOR TO ASSUME THE DESIRED SHAPE AND DENSITY.

Claim 2

THE METHOD OF FORMING A COLORED PICTURE FILM COMPRISING SENSITIZING A FILM OF POLYVINYL ALCOHOL WITH A SOLUTION COMPRISING APPROXIMATELY 250 CC. OF WATER, APPROXIMATELY 5 TO 30 GRAMS OF NAPHTHANIL DIAZO BLUE B SALTS, AND APPROXIMATELY 10 TO 70 GRAMS OF SODIUM PHOSPHATE MONOBASIC TO FORM WITHIN SAID FILM A SENSITIZER OF A DYEFORMING TYPE, EXPOSING SAID SENSITIZED FILM TO ULTRA-VIOLET LIGHT THROUGH A CYAN MASTER COLOR SEPARATION POSITIVE, FOR CAUSING DECOMPOSITION OF SAID SENSITIZER IN ACCORDANCE WITH THE VARYING OPACITY OF SAID CYAN MASTER COLOR SEPARATION POSITIVE, SUBJECTING SAID EXPOSED FILM TO A CYAN COUPLING SOLUTION COMPRISING APPROXIMATELY 200 CC. OF A FIRST STOCK SLOUTION EMBODYING APPROXIMATELY 500 CC. OF SODIUM CHLORIDE AND APPROXIMATELY 1500 CC. OF WATER HAVING ADDED THERETO APPROXIMATELY 30 TO 70 CC. OF A SECOND STOCK SOLUTION EMBODYING APPROXIMATELY 7 TO 14 GRAMS OF POTASSIUM HYDROXIDE AND APPROXIMATELY 400 CC. OF SAID FIRST STOCK SOLUTION AND FURTHER HAVING ADDED THERETO APPROXIMATELY 3 TO 10 GRAMS OF 1 AMINO 8-NAPHTHOL 2,4-DISULFONIC ACID FOR A TIME INTERVAL SUFFICIENT TO PERMIT SAID CYAN COUPLING SOLUTION TO REACT WITH THE UNDECOMPOSED DYEFORMING SENSITIZER IN SAID FILM TO PRODUCE AN IMAGE OF A CYAN COLOR, TREATING SAID FILM WITH A NEUTRALIZING SOLUTION COMPRISING APPROXIMATELY 250 CC. OF SAID FIRST STOCK SOLUTION HAVING APPROXIMATELY 3 TO 30 GRAMS OF CUPRIC CHLORIDE ADDED THERETO FOR STOPPING ACTION OF SAID CYAN COUPLING SOLUTION AND TO CAUSE THE CYAN COLOR TO ASSUME THE DESIRED SHAPE AND DENSITY, RESENSITIZING SAID FILM WITH MORE OF SAID WATER SOLUTIN OF DIAZO SALTS, AND SODIUM PHOSPHATE MONOBASIC, EXPOSING THE RESENSITIZED FILM TO ULTRA-VOILET LIGHT THROUGH A YELLOW MASTER COLOR SEPERATION POSITIVE FOR DECOMPOSING SAID SENSITIZER IN ACCORDANCE WITH THE VARYING OPACITY OF SAID YELLOW MASTER COLOR SEPARATION POSITIVE, SUBJECTING SAID EXPOSED FILM TO A YELLOW COUPLING SOLUTION COMPRISING APPROXIMATELY 200 CC. OF SAID FIRST STOCK SOLUTION, APPROXIMATELY 50 CC. OF SAID SECOND STOCK SOLUTION, AND APPROXIMATELY 1/2 TO 2 CC. OF PHENOL SOLUTION TO REACT WITH THE UNDECOMPOSED SENSITIZER IN SAID FILM TO PRODUCE AN IMAGE ACCORDING TO SAID YELLOW MASTER COLOR SEPARATION POSITIVE, NEUTRALIZING THE FILM IN MORE OF SAID MENTIONED NEUTRALIZING SOLUTION FOR PRODUCING THE DESIRED YELLOW SHADE AND DENSITY, RESENSITIZING SAID FILM WITH MORE OF SAID WATER SOLUTION OF DIAZO SALT AND SODIUM PHOSPHATE MONOBASIC, EXPOSING THE RESENSITIZED FILM TO ULTRA-VOILET LIGHT THROUGH A MAGENTA MASTER COLOR SEPARATION POSITIVE FOR DECOMPOSING SAID SENSITIZER IN ACCORDANCE WITH THE VARYING OPACITY OF SAID MAGENTA MASTER COLOR SEPARATION POSITIVE, SUBJECTING SAID EXPOSED FILM TO A MAGENTA COUPLING SOLUTION COMPRISING APPROXIMATELY 225 CC. OF SAID FIRST STOCK SOLUTION, APPROXIMATELY 15 TO 50 CC. OF SAID SECOND STOCK SOLUTION AND APPROXIMATELY 5 TO 20 CC. OF ALCOHOL HAVING DISSOLVED THEREIN APPROXIMATELY .3 TO .5 CC.
