Abstract

Abstract A COMPOSITE INTEGRAL LIGHT-SENSITIVE PHOTOGRAPHIC MATERIAL FOR FORMING COPIES BY MEANS OF THE DIFFUSION TRANSFER PROCESS COMPRISING IN SUCCESSIVE ORDER A TRANSPARENT FLEXIBLE SUPPORT SHEET AND IMAGE-RECEIVING LAYER COMPRISING DEVELOPMENT NUCLEI, A PIGMENT LAYER CONTAINING AN OPAQUE WHITE OR COLORED PIGMENT DISPERSED IN A HYDROPHILIC COLLOID BINDER, WHEREIN THE PIGMENT AND THE BINDER OF THE PIGMENT PARTICLES ARE PRESENT IN AN AMOUNT OF FROM 7 TO 25 G. PER SQ. M. AND OF FROM 0.5 TO 4 G. SQ. M., RESPECTIVELY, AND A LIGHT-SENSITIVE SILVER HALIDE EMULSION LAYER, THE MAXIMUM DEVELOPED REFLEX DENSITY OF WHICH IS EQUAL TO OR LOWER THAN 0.8. A PHOTOGRAPHIC METHOD USING SUCH MATERIAL IS ALSO DISCLOSED. THE DEVELOPED MATERIAL HAS A POSITIVE IMAGES IN THE IMAGE-RECEIVING LAYER WHICH IS VISIBLE DIRECTLY THROUGH THE TRANSPARENT SUPPORT SHEET, TOGETHER WITH A NEGATIVE IMAGE IN THE EMULSION LAYER WHICH IS HIDDEN FROM THE POSITIVE IMAGE BY MEANS OF THE INTERVENING PIGMENT LAYER SO THAT THE MATERIAL CAN BE EXPOSED, DEVELOPED AND VIEWED IN THE FORM OF AN INTEGRAL ASSEMBLY WITHOUT SEPARATION OF THE PARTS THEREOF.
