发明名称 Photographic silver halide developer composition and method
摘要 <p>The present invention provides a black-and-white aqueous alkaline photographic developer composition and a method of processing an exposed photographic silver halide element comprising the steps of developing by means of a developer comprising a silver halide developing agent and treating the developed element with a fixer composition, wherein the developer composition, free of dihydroxybenzene developing agents, comprises : a) a developing agent corresponding to general formula (I), its salts and mixture thereof: &lt;CHEM&gt; wherein X represents an oxygen atom or an imino group; n represents a positive integer from 1 to 4, and R represents a hydroxy group when n is 1, and a hydroxy group or a hydrogen atom when n is 2 to 4; b) a superadditive auxiliary developing agent; and c) a combination of carbonate and borate compounds as buffering agents.</p>
