    • A method of processing a direct positive silver halide photographic light-sensitive material which comprises processing a direct positive silver halide photographic light-sensitive material comprising a support having coated thereon at least one hydrophilic colloid layer containing a compound represented by the following general formula (I):R.sup.1 NHNHCOR.sup.2 (I)wherein R.sup.1 represents an unsubstituted or substituted aryl group or an unsubstituted or substituted alkyl group; and R.sup.2 represents a hydrogen atom, an unsubstituted or substituted aryl group or an unsubstituted or substituted alkyl group, with a developing solution containing not less than 25 g per liter of a hydroquinone and having a pH of from 11.0 to 13.0. According to the processing method an excellent reversal photographic image can be obtained using a high pH type developing solution which is stable wherein a change of pH due to exhaustion and aerial oxidation is considerably small.

    • A direct positive silver halide sensitive material and a method of treating the material are disclosed. The method of treatment comprises providing an exposed direct positive silver halide sensitive material comprised of a base having thereon a compound represented by the general formula (I) and a sensitive silver halide photographic emulsion layer. The material is then developed in the presence of a compound represented by the general formula (II). ##STR1## the substituents within the general formula are defined in the specification. ##STR2## the substituents within this general formula are also defined in the specification. The use of the compounds represented by the general formulae (I) and (II) provide an image with improved sharpness and edge effect. Furthermore, the process can be carried out without substantial variations in the reversal property due to variations in the bromine ion concentration of the developing solution or the pH thereof.
    • 公开了一种直接的正卤化银感光材料及其处理方法。 处理方法包括提供一种曝光的直接正性卤化银感光材料,其包含其上具有由通式(I)表示的化合物的碱和敏感的卤化银照相乳剂层。 然后在由通式(II)表示的化合物的存在下显色该材料。 (I)通式中的取代基在说明书中定义。 (II)该通式中的取代基也在说明书中定义。 由通式(I)和(II)表示的化合物的使用提供了具有改善的清晰度和边缘效果的图像。 此外,由于显影液的溴离子浓度的变化或其pH的变化,可以进行反转性能的实质性变化。
