Direct-positive silver halide photographic material

Direct-positive silver halide photographic material. Sasagawa, Masayuki; Tosaka, Yasuo; Nonaka, Yoshiyuki (Konica Co., Japan). Jpn. Kokai Tokkyo Koho JP 03138641 A2 13 Jun 1991 Heisei, 22 pp. 14070-48-5 and 58089-28-4 are also occured in this study. (Japan). CODEN: JKXXAF. CLASS: ICM: G03C001-485. ICS: G03C001-035; G03C001-06. APPLICATION: JP 89-278055 25 Oct 1989. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) A Ag halide photog. material having 31 Ag halide photog. emulsion layer contg. unprefogged (definition given), internal latent image-type Ag halide grains, which is subjected to surface-development sequentially, involving imagewise exposure, fogging processing, and/or fogging processing to obtain direct pos. image, contains 380 mol% AgCl and latent image-type Ag halide grains formed in the presence of compd. selected from pyrimidine or imidazole derivs. [I; Z1 = atoms to form (un)substituted 5- or 6-membered N-contg. heterocyclic ring optionally fused to carbocyclic ring; Y = aliph. or arom. group] and azole derivs. [II; Z = atoms to form (un)substituted oxadiazole, thiadiazole, triazole, tetrazole, triazine, benzimidazole, naphthimidazole, benzoxazole, or naphthoxazole ring; M = H, alkali metal atom, NH4 or its precursor]. This photog. material shows processing stability and rapidly provides pos. images having sufficiently high max. d. and low min. d. .

Silver halide color photographic material

Silver halide color photographic material. Otani, Shigeaki; Ono, Shigeru (Fuji Photo Film Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 03156450 A2 4 Jul 1991 Heisei, 64 pp. (Japan). CODEN: JKXXAF. CLASS: ICM: G03C007-20. ICS: G03C007-392. APPLICATION: JP 89-297214 14 Nov 1989. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) In a Ag halide color photog. material comprising at least one Ag halide photosensitive layer on a reflective support having a support substrate coated with a H2O-resistant resin layer, the H2O-resistant resin layer present on the side of the support having the Ag halide photosensitive layer coated contains 314 wt.% TiO2 grains, whereas the photog. material has 30. 13463-67-7 and 14070-48-5 are also in the experiment.70 optical d. at 680 nm and contains at least one azole deriv. [I; Q = atoms to form a (benzene-fused) 5- or 6-membered heterocycle; M = H, a cation] and/or at least one N heterocycle [II; D = a divalent arom. residue; R12-R14 = H, OH, alkoxy, aryloxy, halogen, heterocyclyl, (un)substituted SH or NH2, aryl; Q1, Q2 = N, CH; at least one of Q1, Q2 = N]. The photog. material provides excellent sharpness and shows little change in sensitivity when the humidity changes during the exposure. .
