Claim 1

IN THE ART OF PRODUCING A COLORED THREE-DIMENSIONAL PICTURE EMBODYING STEROSCOPICALLY DISPLACED PICTURE COMPONENTS, WHICH COMPONENTS ARE THE COMPOSITE OF PLURAL AREAS OF DIFFERENT COLORS IN A SINGLE FILM OF POLYVINYL ALCOHOL HAVING ITS MOLECULES HIGHLY ORIENTED IN A DIRECTION DISPOSED SUBSTANTIALLY AT 45* WITH RESPECT TO THE HORIZONTAL MERIDIAN OF SAID FILM, THE STEPS OF FIRST SENSITIZING SAID FILM WITH A DYE-FORMING NAPHTHANIL DIAZO BLUE B SALT SOLUTION, EXPOSING SAID SENSITIZED FILM TO ULTRA-VIOLET LIGHT THROUGH A CYAN MASTER COLOR SEPARATION POSITIVE EMBODYING A PAIR OF MIRROR IMAGES WHICH ARE STEREOSCOPIC COMPLEMENTS OF EACH OTHER 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 CONTAINING A RELATIVELY HIGH CONCENTRATION OF APPROXIMATELY 35.7 GRAMS PER 100 CCS. WATER OF SALT SELECTED FROM A GROUP CONSISTING OF SODIUM PHOSPHATE, SODIUM SULPHATE, SODIUM CHLORIDE, AND POTASSIUM CHLORIDE, AND A COUPLER COMPOUND WHICH WILL COUPLE WITH THE UNDERCOMPOSED DYE-FORMING SENSITIZER FOR A TIME INTERVAL SUFFICIENT TO PERMIT SAID CYAN COUPLING SOLUTION TO REACT WITH SAID UNDECOMPOSED DYE-FORMING SENSITIZER IN SAID FILM AND THEREBY PRODUCE THE DESIRED CYAN COLORED STERO PAIR OF PICTURE AREAS AND SIMULTANEOUSLY RENDERING THE MOLECULES LIGHT POLARIZING, TREATING SAID FILM WITH A NEUTRALIZING CUPRIC CHLORIDE SOLUTION TO CAUSE SAID CYAN COLORED PICTURE AREAS TO ASSUME THE DESIRED SHADE AND TO STOP THE ACTION OF AND TO NEUTRALIZE SAID COUPLER, THEREBY RECONDITIONING THE POLYVINYL FILM FOR RESENSITIZATION WITHOUT DISCOLORATION AND, BY REASON OF SAID HIGH SALT CONCENTRATION IN SAID CYAN COUPLING SOLUTION, PREVENTING DISORIENTATION OF THE MOLECULES WHICH HAVE BEEN RENDERED DICHROIC BY SAID CYAN COUPLING SOLUTION, AND SUCCESSIVELY REPEATING THE ABOVE STEPS FOR AT LEAST TWO ADDITIONAL COLORS, ONE COMPRISING RESENSITIZING THE FILM WITH SAID DYE-FORMING NAPHTHANIL DIAZO BLUE B SALT SOLUTION, EXPOSING THE RESENSITIZED FILM TO ULRA-VIOLET LIGHT THROUGH A YELLOW MASTER COLOR SEPARATION POSITIVE HAVING IMAGE CHARACTERISTICS SIMILAR TO THE CYAN MASTER COLOR SEPARATION POSITIVE AND SUPPORT IN PROPER SUPERIMPOSED POSITIONAL RELATION WITH THE FIRST FORMED PICTURE AREAS 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 CONTAINING A RELATIVELY HIGH CONCENTRATION OF APPROXIMATELY 35.7 GRAMS PER 100CCS. WATER OF SALT SELECTED FROM THE GROUP CONSISTING OF SODIUM PHOSPHATE, SODIUM SULPHATE, SODIUM CHLORIDE AND POTASSIUM CHLORIDE, AND A COUPLER COMPOUND WHICH WILL COUPLE WITH THE UNDECOMPOSED DYE-FORMING SENSITIZER FOR A TIME INTERVAL SUFFICIENT TO PRODUCE THE DESIRED YELLOW COLOR BY REACTION WITH THE UNDECOMPOSED SENSITIZER, AND AGAIN TREATING SAID FILM WITH SAID CUPRIC CHLORIDE SOLUTION FOR PRODUCING THE DESIRED YELLOW SHADE AND TO STOP THE ACTION OF AND TO NEUTRALIZE SAID COUPLER, AND THE OTHER COMPRISING AGAIN RE-SENSITIZING THE FILM AND EXPOSING SAID FILM TO ULTRAVIOLET LIGHT THROUGH A MAGENTA COLOR SEPARATION POSITIVE HAVING SIMILAR CHARACTERISTICS TO SAID FIRST-MENTIONED COLOR SEPARATION POSITIVES AND SUPPORTED IN PROPER SUPERIMPOSED POSITIONAL RELATION WITH SAID FIRST FORMED AREAS FOR DECOMPOSING SAID SENSITIZER IN ACCORDANCE WITH THE VARYING OPACITY OF SAID MAGENTA MASTER COLOR SEPARATION POSITIVE, SUBJECTING SAID EXOSED FILM TO A MAGENTA COUPLING SOLUTION CONTAINING A REALTIVELY HIGH CONCENTRATION OF APPROXIMATELY 35.7 GRAMS PER 100 CCS. WATER OF SALT SELECTED FROM THE GROUP CONSISTING OF SODIUM PHOSPHATE, SODIUM SULPHATE, SODIUM CHLORIDE AND POTASSIUM CHLORIDE, AND A COUPLER COMPOUND WHICH WILL COUPLE WITH THE UNDECOMPOSED DYE-FORMING SENSITIZER FOR A TIME INTERVAL SUFFICIENT TO PRODUCE THE DESIRED MAGENTA COLOR BY REACTION WITH THE UNDECOMPOSED SENSITIZER, AND THEREAFTER TREATING SAID FILM WITH SAID CUPRIC CHLORIDE SOLUTION TO CAUSE THE MAGENTA COLORED AREAS TO ASSUME THE DESIRED SHADE AND COLOR AND TO STOP THE ACTION OF AND TO NEUTRALIZE SAID COUPLER, THEREAFTER FOLDING SAID TREATED SHEET OF POLYVINYL ALCOHOL TO POSITION THE RESULTANT MIRROR PICTURE AREAS IN PROPER STEREOSCOPIC RELATION WITH EACH OTHER AND SECURING SAID SUPERIMPOSED LAYERS TOGETHER IN SAID RELATION WHEREBY THE AXES OF POLARIZATION OF SAID SUPRIMPOSED LAYERS DUE TO SAID FOLDING WILL ASSUME A DESIRRED 90* RELATION WITH EACH OTHER.
