Definitions

  • R represents an alkyl group or a group of the formula and R stands for hydrogen or an amino group or a group of the formula NH-(HJR4 and R stands for an alkyl group.
  • the present invention relates to heat developing-out.
  • the present invention relates to heat developing-out photosensitive materials consisting of the following components:
  • the silver halide photosensitive materials used in the silver halide photographic process require treatments such as stopping, fixation, water washing, stabilization, etc., so that when the material is exposed to form an image and is subjected to development using a developer the developed image is not discolored or faded by light or the part not developed (hereafter referred to as background) is not blackened.
  • the process involves various problems such as it takes a long time for the treatments, the treatments involve chemical agents dangerous to humans and further the interior of the treating room as wellas the hands and the clothes of operators can be contaminated with the chemical agents. Under these circumstances, it would be desirable to improve photographic processes using a silver halide so that the silver halide photosensitive material used in the processes could be treated in the dry state without being subjected to treatment solutions and that the treated images would be stable.
  • Still another suggestion is to try to use as a main ingredient a photosensitive element such as a silver salt of an aliphatic carboxylic acid, e.g. behenic acid, or a silver salt such as silver saccharin or silver benzotriazole, and a catalytic amount of a silver halide described, for example, in Japanese Pats. 4,921/ 68, 4,924/68, 26,582/69, 18,416/70, 12,700/70 and 22,186/ 70 and British Pat. 1,205,500.
  • a photosensitive element such as a silver salt of an aliphatic carboxylic acid, e.g. behenic acid, or a silver salt such as silver saccharin or silver benzotriazole, and a catalytic amount of a silver halide described, for example, in Japanese Pats. 4,921/ 68, 4,924/68, 26,582/69, 18,416/70, 12,700/70 and 22,186/ 70 and British Pat. 1,205,500.
  • phthalazinone which is effective in the known composition including silver behenate is not effective in the composition of the present invention including as an image forming compound silver benzothiazole. This will be substantiated in the comparative examples hereunder described.
  • Silver benzothiazole is superior to silver behenate as an image forming compound since the former is more stable to heat than the latter, and so heating fog hardly occurs in a photosensitive material including silver benzotriazole when the nonexposed part thereof is heated, and as a' result an image having good contrast between the image and the background is obtained. Therefore, it is desirable to provide compounds which are able to form an image of an excellent black shade in a heat developingout photosensitive material which includes silver benzotriazole.
  • the present invention belongs to the last class of methods described above and provide heat developing-out photosensitive materials including silver benzothiazole and a silver halide.
  • the present invention is based upon the discovery that an image having an excellent black shade can be obtained using a heat developing-out photosensitive material which. comprises the following ingredients:
  • R represents hydrogen or an alkyl group or a group of the formula where R represents an alkyl group or a group of the formula where R represents hydrogen or an amino group or a group of the formula and where R represents an alkyl group.
  • the following ingredients are subjected to ball milling for several hours at about 25 C. under atmospheric pressure to make a dispersion.
  • Dispersion A The thus prepared dispersion will hereafter be referred to as Dispersion A.
  • Dispersion A a coating composition is formed using Dispersion A mixed with the following ingredients:
  • Dispersion A (mixed with the following four components in whole amount as above);
  • Methanol solution including 5% by weight of mercuric bromide and 8.5% by weight of mercuric iodide 1 iAcetone solution including 0.2%* by weight of benzoxazolilidene thiohydantoin sensitizing dye 1 Methyl Cellosolve solution including 25% by weight of ascorbic acid monopalmitate 8 Methyl Cellosolve solution including 5% by weight of a compound (5) of the present invention 1
  • the resulting composition is applied to a polyethylene terephthalate support such that the amount of the silver in the coated composition is 1.3 g. per 1 m? of the support.
  • the thus formed coating is left under atmospheric 4 pressure at about 50-70 C. and dried to substantial solidity.
  • This element is image-wise exposed to tungsten light for 2 minutes and then the thus exposed element is put between heated plates and heated for 30 seconds at C.
  • the resulting image is compared with an image obtained by using phthalazinone. It is confirmed that by using a compound (5) of the present invention an image of a black shade is obtained, While using phthalazinone an image of a brown shade is obtained. Specific working examples in this respect will be given in the following material.
  • the amount of the compound or compounds of formula (5) to be added which are effective as a black shade imparting agent in the present invention is preferably 0.0001-1 mol per 1 mol of silver benzotriazole. This amount may vary, depending upon the kind of the compound to be used, the kinds of the respective ingredients in the photosensitive material, treating temperature, etc., but the above range covers most commercial embodiments.
  • the silver benzotriazole used in the present invention is a silver salt which is stable to light, and only in parts wherein exposed silver halide is present and which are heated, is the silver salt reduced by the action of a reducing agent to form a silver image.
  • the absolute amount of the silver benzotriazole present in the element can vary greatly, and is not particularly limited so long as a sufiicient amount is present to form an acceptable image. Generally speaking from about 0.5 to about 10 g. of silver benzotriazole will be present per square meter of support, more preferably 1 g. to 6 g. At lesser amounts, occasionally inferior results will be obtained, while no better effect is obtained at greater amounts as compared to about 10 g./m.
  • the reducing agents to be used in the present invention must be ones which are suitable for reducing silver benzotriazole upon being heated in the presence of the exposed silver halide to form the silver image, as mentioned above.
  • the silver benzotriazole is more stable to heat than silver behenate as already explained, and so it is hardly reduced under heat. Therefore, known reducing agents which are eifective with silver behenate are almost ineffective for silver benzotriazole, since the reducing ability of such known reducing agents is weak and so the silver benzotriazole is reduced only with difficulty.
  • ascorbic acid and/ or an ascorbic acid derivative is (are) a suitable reducing agent which is effective for reducing silver benzotriazole.

  • a mixture of ascorbic acid or derivatives thereof, a mixture of 3-pyrazolidone derivatives, or a mixture of ascorbic acid or derivatives thereof and 3-pyrazolidone derivatives may also be used if desired.
  • the amount of the reducing agent used in the present invention is preferably 0.1-5 mols per 1 mol of silver benzotriazole.
