The direct positive photographic recording material and with the use of the same owned and managed by a method for producing a directly positive image

摘要

PURPOSE:To form an internal latent image type silver halide photographic material for direct positive image formation at a high rate of fogging development and yet without stain, by adding a specified compound to a photosensitive material layer. CONSTITUTION:A compound represented by general formula I (R1, R2, R3 are H, halogen, alkyl, or aryl; R4 is H, halogen, alkyl, alkoxy, acyl, amino, aryl, aryloxy, nitro, hydroxy, carboxy, or alkoxycarbonyl), such as formula II or III is added to a silver halide emulsion layer or an adjacent layer in an amount of about 0.001- 1, preferably 0.001-0.5 mole per mole of silver halide.
