Claim 1

A PROCESS FOR SIMULTANEOUSLY PRODUCING FROM A SINGLE NEGATIVE (I) A POSITIVE LATERALLY REVERSED PRINTING FORM AND (II) A NEGATIVE NON-LATERALLYR EVERSED PRINTING FORM WHICH COMPRISES: (A) EXPOSING INAGEWISE TO AN OBJECT TO BE REPRODUCED A LIGHT-SENSITIVE NEGATIVE SHEET COMPRISING ALIGHTSENSITIVE SILVER HALIDE LAYER ADHERING TO A NEGATIVE SHEET SUPPORTING LAYER, (B) DEVELOPING THE EXPOSED LIGHT-SENSITIVE NEGATIVE SHEET IN A DEVELOPER CONTAINING A SILVER HALIDE SOLVENT WHEREBY THE SILVER HALIDE IN THE EXPOSED AREAS OF THE EMULSION LAYER IS CONVERTED TO A SILVER IMAGE AND THE SILVER HALIDE IN THE NON-EXPOSED AREAS OF THE EMULSION LAYER IS DISSOLVED, (C) BRINGING THE EXPOSED EMULSION LAYER OF THE NEGATIVE SHEET DURING DEVELOPMENT INTO CONTACT WITH AN AMOUNT OF DEVELOPMENT NUCLEI SUFFICIENT TO INCREASE THE ADHESIVENESS OF A TRANSFER SHEET TO THE EMULSION LAYER BUT AN AMOUNT LESS THAN THAT WHICH CAUSES A VISIBLE SILVER PRECIPITATION IN THE TRANSFER SHEET, SAID DEVELOPMENT NUCLEI BEING SELECTED FROM THE GROUP CONSISTING OF HEAVY METALS, HEAVY METAL SULFIDES AND HEAVY METAL SELENIDES AND INTO CONTACT WITH A TRANSFER SHEET, SAID TRANSFER SHEET CONSISTING ESSENTIALLY OF A TRANSFER LAYER OF A FILM-FORMING CARBOXYSUBSTITUTED CARBOHYDRATE HAVING A PYRANOSIDE STRUCTURE AND CONTAINING BETWEEN 10 AND 50 PERCENT BY WEIGHT CARBOXYL RADICALS ADHERING TO A TRANSFER SHEET SUPPORTING LAYER WHEREBY SILVER HALIDE DISSOLVED FROM THE UNEXPOSED AREAS OF THE EMULSION LAYER DIFFUSES IMAGEWISE INTO THE TRANSFER LAYER THEREBY INCREASING IMAGEWISE THE ADHESIVENESS OF THE TRANSFER LAYER TO THE EMULSION LAYER, AND (D) SEPARATING THE TRANSFER SHEET AND THE NEGATIVE SHEET WHEREBY THOSE PORTIONS OF THE TRANSFER LAYER WHICH WERE IN CONTACT WITH THE UNEXPOSED AREAS OF THE EMULSION LAYER NOW ADHERETO THE EMULSION LAYER AND THOSE PORTIONS OF THE TRANSFER LAYER WHICH WERE IN CONTACT WITH THE EXPOSED AREAS OF THE EMULSION LAYER REMAIN ADHERING TO THE TRANSFER SHEET SUPPORTING LAYER THEREBY PRODUCING (I) A POSITIVE LATERALLY REVERSED PRINTING FORM COMPRISING THE NEGATIVE SHEET AND A RELIEF LAYER OF PORTIONS OF THE TRANSFER LAYER AND (II) A NEGATIVE NON-LATERALLY REVERSED PRINTING FORM COMPRISING THE TRANSFER SHEET SUPPORTING LAYER AND A RELIEF LAYER OF THE REMAINING PORTION OF THE TRANSFER LAYER.
