the figure is a flow sheet setting forth the steps of. the method.
PATENT OFFICE the eflectiveness of the bath decreases with increasing depth of layer, so'that the period of treatment of the dyestufi-destroying agents would in the case of a plurality of silver halide layers poured one on to the other be relatively iilong, when using a normal quantity of silver.
the increased quantity of silver is obtained by known means by corresponding exposure and development.
This method may also be made use of in the 35 additional treatment of sensitized materials containing dyestuflf-forming substances.
the dis solution of the silver takes place in a desired reducing bath.
merely neutral'reducers, or reducers which do not exert a vigorous action may be employed, i. e., which do not act on the dyestufl image in such manner as to vary the same.
the images proceeding from the dyestuif-destroying bath are rinsed briefly and additionally treated in one of the baths above referred to for the purpose. of-bleaching out the silver image, which operation is usually completed in 1 to 2 minutes, whereupon the images are immersed for 30 seconds in a 20% fixing sodium solution, whereby the silver chloride formed is dissolved away. Washing isthereupon again'eil'ected for a brief period.
the images thus produced are of an ex cellent kind, fast in color, and also remarkably resistant to washing.
a method of producing photographic dyestuil images inphotographic layers, which are colored with dyestufls or contain dyestuif-forming substances in the emulsion which consists in initially producing by exposure and develop-f as in the case of other reducing a reducing agent is ment an'image having an amount of silver in excess of that normally required for the destruction of the dyestui! and subsequently subjecting the image to a dye-destroying bath wherein a part of the silver assists in the destruction of the dyestufl, then subjecting the image to a dye-destroying bath surplus silver by subjecting the image toa bath containing weak reducer.
a method of producing photographic dyestufl images in photographic layers, which are colored with dyestuffs or contain dyestuir-forming substances in the emulsion which consists in initially producing by exposure anddevelopment an image having an amount of silver in excess of that normally required for the'destruction of the dyestuii', then subjecting the image to a dyedestroying bath wherein a part of the silver aids in the dyestuif destruction, and subsequently removing the surplus silver by subjecting the image to a bath containing a cupric salt to obtain a rapid bleaching out action without a dyestufl discharging effect.
a method of producing photographic dyestuil' images in photographic layers, which are colcred with dyestufls which consists in initially producing by exposureand development an image having an amount of silver in excess of that normally required for the destruction of the dyewherein a part of the silver aids stuff, then subjecting the image-to a dyestui! destroying bath, rinsing the image in a bathcontaining a cupric salt to form a silver halide, next immersing the'image in a'flxing solution to wash away the silver halide, and subsequently washing the image for a brief period to produce the final image.
