Abstract: A process for processing exposed photographic silver halide materials at least comprising the stages color development, stopping, bleaching and fixing using a bleaching bath with hydrogen peroxide as the active substance, characterized in that the stop bath contains as a buffer agent at least one carboxylic acid of the formulae I to VIII ##STR1## in which R.sub.1 to R.sub.5 mutually independently mean hydrogen, --OH, --COOM, --SO.sub.3 M, --PO(OM).sub.2, an optionally substituted alkyl residue, an optionally substituted aryl residue, an optionally substituted amino residue or a heterocyclic residue andM means hydrogen or an alkali metal atom and wherein at least one further acid group is present in the molecule, ##STR2## and at least one agent which stops development, is distinguished by improved bleaching action and the use of an environmentally friendly bleaching bath.

Abstract: A bleaching bath for processing photographic silver halide materials with hydrogen peroxide as the active substance, characterised in that it contains at least one organic compound having a sulfinic acid function and a further functional group with free electron pairs, is distinguished by improved bleaching action and makes it possible to achieve continuous processing of hard to bleach photographic materials having an elevated silver content.

Abstract: In the production of a colour photographic image in a continuous process comprising at least the stages a) treatment with a bath containing H.sub.2 O.sub.2 or a bath containing a compound which liberates H.sub.2 O.sub.2 and b) fixing, wherein stage b) immediately follows stage a), precipitation of silver oxide and silver is avoided if the fixing bath contains an anti-oxidant and a buffer substance in addition to the fixing agent, a molar ratio of anti-oxidant to fixing agent of >0.2 is maintained and the quantity of buffer substance is >0.4 mol/l.
