Diffusion transfer of dichroic iodine stain in vectograph production

Claim 1

THE METHOD OF TRANSFERRING IMAGE INFORMATION ONTO A TRANSPARENT VECTOGRAPH FILM MEMBER FROM A CONVENTIONAL PHOTOGRAPHIC MASTER MEMBER INCLUDING A BACKING SUPPORT HAVING ON ONE SIDE THEREOF A CONTINUOUS LAYER OF WATER ABSORPTIVE MATERIAL CONTAINING FULLY DEVELOPED IMAGE MEANS AND BACKGROUND MEANS, ONE OF SAID MEANS EMBODYING REDUCED METALLIC SILVER AND THE OTHER OF SAID MEANS BEING FREE FROM SAID REDUCED METALLIC SILVER, SAID VECTOGRAPH MEMBER EMBODYING A SUPPORT OF TRANSPARENT MATERIAL HAVING A CONTINUOUS LAYER OF WATER ABSORPTIVE MATERIAL LAMINATED TO AT LEAST ONE SIDE THEREOF WITH ITS MOLECULES ORIENTED IN A GIVEN DIRECTION; SAID METHOD COMPRISING THE STEPS OF APPLYING TO SAID CONTINUOUS LAYER OF WATER ABSORPTIVE MATERIAL OF SAID VECTOGRAPH MEMBER AN AQUEOUS STAINING SOLUTION CONTAINING A DICHROIC IODINE STAIN CAPABLE OF BEING BLEACHED BY REDUCED METALLIC SILVER, WETTING SAID PHOTGRAPHIC MASTER MEMBER SUFFICIENTLY TO SOFTEN SAME, PLACING SAID WATER ABSORPTIVE LAYERS OF SAID MASTER MEMBER AND VECTOGRAPH MEMBER IN DIRECT CONTACT WITH EACH OTHER AND RETAINING THE SAME IN SAID RELATIONSHIP FOR A TIME INTERVAL SUFFICIENT TO CAUSE SAID REDUCED METALLIC SILVER IN SAID MASTER MEMBER TO ELIMINATE BY BLEACHING THE PRESENCE OF DICHROISM OF SAID STAIN IN SAID VECTOGRAPH MEMBER THROUGHOUT AREAS WHERE SAID METALLIC SILVER CONTACTS SAID VECTOGRAPH MEMBER, SEPARATING SAID MASTER AND VECTOGRAPH MEMBERS AND SUBJECING SAID VECTOGRAPH TO A FIXING SOLUTION TO STABILIZE SAME.

Claim 2

THE METHOD OF TRANSFERRING IMAGE INFORMATION ONTO A TRANSPARENT VECTOGRAPH FILM MEMBER FROM A CONVENTIONAL PHOTOGRAPHIC MASTER MEMBER INCLUDING A BACKING SUPPORT HAVING ON ONE SIDE THEREOF A CONTINUOUS LAYER OF WATER ABSORPTIVE MATERIAL CONTAINING FULLY DEVELOPED IMAGE MEANS AND BACKGROUND MEANS, ONE OF SAID MEANS EMBODYING REDUCED METALLIC SILVER AND THE OTHER OF SAID MEANS BEING FREE FROM SAID REDUCED METALLIC SILVER, SAID VECTOGRAPH MEMBER EMBODYING A SUPPORT OF TRANSPARENT MATERIAL HAVING A CONTINUOUS LAYER OF WATER ABSORPTIVE MATERIAL LAMINATED TO AT LEAST ONE SIDE THEREOF WITH ITS MOLECULES ORIENTED IN A GIVEN DIRECTION; SAID METHOD COMPRISING THE STEPS OF APPLYING TO SAID CONTINUOUS LAYER OF WATER ABSORPTIVE MATERIAL OF SAID VECTOGRAPH MEMBER AN AQUEOUS STAINING SOLUTION CONTAINING A DICHROIC IODINE STAIN CAPABLE OF BEING BLEACHED BY REDUCED METALLIC SILVER, WETTING SAID PHOTGRAPHIC MASTER MEMBER SUFFICIENTLY TO SOFTEN SAME, PLACING SAID WATER ABSORPTIVE LAYERS OF SAID MASTER MEMBER AND VECTOGRAPH MEMBER IN DIRECT CONTACT WITH EACH OTHER AND RETAINING THE SAME IN SAID RELATIONSHIP FOR A TIME INTERVAL SUFFICIENT TO CAUSE SAID REDUCED METALLIC SILVER IN SAID MASTER MEMBER TO ELIMINATE BY BLEACHING THE PRESENCE OF DICHROISM OF SAID STAIN IN SAID VECTOGRAPH MEMBER THROUGHOUT AREAS WHERE SAID METALLIC SILVER CONTACTS SAID VECTOGRAPH MEMBER, SEPARATING SAID MASTER AND VECTOGRAPH MEMBERS AND SUBJECING SAID VECTOGRAPH TO A FIXING SOLUTION TO STABILIZE SAME.
