    • A method for forming a direct positive color image by subjecting an inner latent image type light-sensitive silver halide color photographic material for formation of a direct positive color image, having at least one light-sensitive emulsion layer containing inner latent image type silver halide grains which have not been previously fogged on the grain surfaces to color developing processing after image exposure, which comprises developing an inner latent image type light-sensitive silver halide color photographic material for formation of a direct positive color image wherein a silver halide emulsion in at least one light-sensitive emulsion layer consists substantially of a silver chlorobromide emulsion with the use of a color developing solution containing an N-hydroxyalkyl-substituted-p-phenylenediamine derivative at 30.degree. C. or higher for not longer than 150 seconds.In accordance with the present invention, there can be provided a rapid and stable method of processing an inner latent image type light-sensitive material for formation of direct positive image by use of a color developer containing the color developing agent of the present invention, which can maintain constantly adequate photographic performance over a long term without suffering from influence by the change in the bromide ion concentration even when processed when reduced supplemental amount and is also little in generation of developing fog.
    • 一种通过对内部潜像型感光卤化银彩色照相材料进行形成直接正色彩图像形成直接正色彩图像的方法,其具有至少一个包含内部潜像型卤化银颗粒的感光乳剂层 其在图像曝光之后未曾在颗粒表面上雾化成彩色显影处理,其包括显影用于形成直接正色彩图像的内部潜像型感光卤化银彩色照相材料,其中至少具有卤化银乳剂 一个感光乳剂层基本上由氯氯化银乳液组成,使用含有N-羟烷基取代的对苯二胺衍生物的显色溶液在30℃以上不超过150秒。 根据本发明,可以提供一种通过使用含有本发明的彩色显影剂的彩色显影剂来处理内部潜像型感光材料以形成直接正像的快速且稳定的方法,其中 即使在减少补充量的同时加工时,也不会在发生雾的同时产生较小的影响,可以长期保持足够的照相性能,而不会受到溴离子浓度变化的影响。

    • A method of storing a liquid color developer and a liquid bleach-fixer in a container made of plastic material having an oxygen permeation coefficient of 0 to 50 m/(m.sup.2 atm day) at temperatures of 20.degree. C. and relative humidity of 60%. The developer contains an aromatic primary amine color developing agent; a hydroxylamine of the formula ##STR1## wherein R.sup.1 and R.sup.2 are hydrogen or alkyl having 1 to 3 carbon atoms, provided that at least one of R.sup.1 and R.sup.2 is an unsubstituted alkyl group having 1 to 3 carbon atoms and that R.sup.1 and R.sup.2 may be combined with each other to form a ring; and an alkaline ingredient for adjusting the pH of the developer to not less than 9.5. The bleach-fixer contains a ferric aminopolycarboxylate, 0 to 1.times.10.sup.-3 mols per liter of an aminopolycarboxylic acid based on the total bleach-fixer, a thiosulfate, and 1.times.10.sup.-3 to 2.times.10.sup.-1 mol per liter of said liquid bleach-fixer of a sulfite.
