Patent number: 4504572Abstract: Silver halide photographic elements for tanning development including tanning developers, which can diffuse into the gelatin layer containing them, can be improved if they are associated with non-diffusing hydroquinones. In the case where such tanning developer is hydroquinone or a derivative thereof, said elements include such diffusing hydroquinone associated with a hydroquinone derivative non-diffusing in the gelatin layer containing it. Such non-diffusing hydroquinones preferably are hydroquinones substituted with aliphatic chains containing a total of at least twelve carbon atoms and, more preferably, are dispersed in the layer dissolved in a high-boiling organic solvent.Type: GrantFiled: August 4, 1983Date of Patent: March 12, 1985Assignee: Minnesota Mining and Manufacturing CompanyInventors: Marco Beruto, Antonio Luzzi, Piero Ramello

Patent number: 4495273Abstract: Silver halide photographic elements comprising a support on which there is spread a plurality of photosensitive layers of gelatin incorporating silver halides and containing coupling agents, and further being associatd with auxiliary gelatin layers tend to suffer from brittleness. An improved element comprises, spread over said support and under said plurality of photosensitive layers, a layer of gelatin in which there is dispersed a fragility reducing quantity of droplets of a water-immiscible high boiling organic solvent, and an adhesion promoting quantity of a vinyl addition polymer latex.Type: GrantFiled: September 3, 1981Date of Patent: January 22, 1985Assignee: Minnesota Mining and Manufacturing CompanyInventor: Mario Pannocchia

Patent number: 4481284Abstract: A silver halide photographic light-sensitive material is disclosed, comprising a support having thereon at least one light-sensitive silver halide emulsion layer and a light-insensitive uppermost layer. The light-insensitive uppermost layer has a melting time longer than that of the light-sensitive silver halide emulsion layer and a thickness of the light-insensitive uppermost layer is from 0.3 .mu.m to 0.8 .mu.m. The silver halide photographic light-sensitive material causes a remarkably lower degree of reticulation, can reduce the amount of scum formed in the processing solution, and has an improved covering power.Type: GrantFiled: September 21, 1982Date of Patent: November 6, 1984Assignee: Fuji Photo Film Co., Ltd.Inventors: Masashi Ogawa, Kunio Ishigaki, Nobuyuki Iwasaki, Taku Nakamura

Patent number: 4476218Abstract: A silver halide photographic light-sensitive material is described, which comprises a support, and at least one light-sensitive silver halide emulsion layer and an uppermost layer provided on at least one surface of the support, wherein the melting time of the uppermost layer is made greater than that of the light-sensitive silver halide emulsion layer. The material has good strength and produces a reduced amount of scum which normally occurs in the processing liquid during development processing.Type: GrantFiled: June 16, 1982Date of Patent: October 9, 1984Assignee: Fuji Photo Film Co., Ltd.Inventors: Masashi Ogawa, Kunio Ishigaki, Taku Nakamura, Nobuyuki Iwasaki

Patent number: 4465751Abstract: An electrophotographic light-sensitive material is disclosed. The material is comprised of a conductive layer containing cuprous iodide and a photoconductive layer. The photoconductive and electrophotographic characteristics are improved by forming a gelatin interlayer between the conductive layer and the photoconductive layer. The electrophotographic light-sensitive material can be used with either positive polarity or negative polarity.Type: GrantFiled: November 24, 1982Date of Patent: August 14, 1984Assignee: Fuji Photo Film Co., Ltd.Inventors: Kouichi Kawamura, Hideo Sato

Patent number: H874Abstract: A silver halide photographic light-sensitive material is disclosed which is excellent in the super-rapid processability. The photographic material comprises a support having thereon at least one hydrophilic colloid layer comprising at least one silver halide emulsion layer. The hydrophilic colloid layer is formed by one or more times of coating provided that wet thickness of the layers coated in each time of coating is within the range of from 35 to 80 .mu.m, and a total content of gelatin of the whole hydrophilic colloid is in an amount of from 2.20 to 3.10 g/m.sup.2. The photographic material is suitable for super-rapid processing by an automatic processor for 20 to 60 seconds.Type: GrantFiled: August 29, 1989Date of Patent: January 1, 1991Assignee: Konishiroku Photo Industry Co., Ltd.Inventors: Akio Suzuki, Satoru Nagasaki
