摘要 |
Latex polymer of fine particles having a heterogeneous phase structure which comprises a core of a polymer having repeating units derived from a conjugated diene monomer and a shell of a polymer having repeating units derived from at least one ethylenically unsaturated monomer carrying an active methylene group; a silver halide photographic light-sensitive material comprises a core/shell latex polymer whose shell consists of a polymer having repeating units of an ethylenically unsaturated monomer represented by the formula: CH2=C(R<1>)-L-X (wherein R<1> represents H, alkyl or halogen, L represents a single bond or a bivalent coupling group, X represents an active methylene group, provided that L is bonded to X in the form of alkylene; and a method for forming images on a silver halide light-sensitive material which comprises exposing the material which comprises at least one light-sensitive silver halide emulsion layer and at least one hydrophilic colloidal layer either of which comprises a latex polymer having active methylene groups and developing the exposed material with a developer which comprises a dihydroxybenzene developing agent and an auxiliary developing agent showing superadditivity, the pH increase observed when adding 0.1mole/ l developer of NaOH to the developer </= 0.25; 9.5 </= initial pH of the developer </= 11.0; the amount of the developer supplemented</= 225 ml/m<2>. <IMAGE> |
