摘要： There is disclosed a direct positive silver halide light-sensitive material which can be propcessed in ultra-rapid processing and have a higher sensitivity, a lower Dmin, an excellent antistatic property and less flactuation of the preperties in storing. The light-sensitive material contains an electron-accepting compound in a silver halide emulsion layer, and a fluorinated surfactant and/or at least one of the compounds represented by Formulas I-a to II-b in a photographic component layer:
wherein R₁ to R₄ represent independently a hydrogen atom, a lower alkyl group, an alkoxy group, a carboxy group, an alkoxycarbonyl group, a sulfo group, a halogen atom, and a nitro group, provided that at least one of R₁ and R₂ is a carboxy group, an alkoxycarbonyl group or a sulfo group.
