    摘要: Process for forming a halftone multicolor pattern which comprises in sequence given the following steps:(1) scanningwise exposing a multicolor original attached to a rotating scanner drum to produce series of electrical signals that are fed into a computer,(2) exposing in a single scan separate black-and-white light-sensitive silver halide emulsion layer materials under the control of the computer in accordance with said signals,(3) developing the exposed silver halide emulsion layers with a hardening or tanning developing agent producing a negative or positive silver selection image that can be used as intermediate original in the production of a printing plate, a pattern of oxidized hardening developing agent being imagewise transferred during development from the emulsion layer onto a hardenable non-photosensitive colored gelatin layer originally carried on a temporary support or carried directly on a permanent support,(4) producing a colored relief image by wash-off processing of said colored gelating layer, and(5) assembling the colored relief images into a multicolor pattern on the same permanent support.

    摘要: In a silver halide photographic material for tanning development, comprising a support base coated with a substantially unhardened hydrophilic binder layer including a light-sensitive silver halide emulsion reactively associated with a tanning developer and a dispersion of colloidal silver, the tendency of the hydrophilic binder to become water-insoluble during storage can be prevented by adjusting the pAg of the colloidal silver dispersion to values in the range from 6.5 to 9.5 with a 1-phenyl-5-mercaptotetrazole compound before coating.

    摘要: Method of purifying an aqueous emulsion containing a silver halide suspended therein and using same in an imaging process which comprises contacting said emulsion with a first ionexchange material which provides one of the ions selected from the class consisting of hydrogen ions and hydroxyl ions and with a second ion-exchange material which provides the opposite ion from that provided by said first ion-exchange material, the time of contact of said emulsion with each of said ion-exchange materials being sufficient to exchange substantially all of the ions in said emulsion for hydrogen and hydroxyl ions, and then separating the emulsion from said ion-exchange materials. The emulsion is applied to a base support exposed to actinic radiation to selectively harden a portion of the surface and then washing away the unhardened layer.

    摘要: A PROCESS OF PRODUCING MASKS PHOTOGRAPHICALLY BY FORMING A DEVELOPED COLLODIAL SILVER IMAGE IN A GELATIN COAING ON A GLASS PLATE AND HEATING THE COATING, AFTER WHICH THE NON-IMAGE AREAS OF THE COATING ARE SELECTIVELY REMOVED BY A GELATIN REMOVING LIQUID SUCH AS AQUEOUS SODIUM HYPOCHLORITE. THE HEATING RENDERS THE SILVER IMAGE AREAS OF THE GELATIN COATING MORE RESISTANT TO THE ACTION OF THE GELATIN REMOVING LIQUID SO THAT THE NON-IMAGE AREAS MAY BE SELECTIVELY REMOVED.
