Abstract (en)

A method has been disclosed of processing an exposed silver halide photographic material comprising at least one coated hydrophilic silver halide emulsion layer comprising tabular grains rich in chloride, bounded by Ä100Ü or Ä111Ü major faces, characterised by the steps of developing, followed by fixing, rinsing and drying the said material, wherein developing proceeds in a developer. comprising hydroquinone in an amount from 0 to 30 g per litre, an auxiliary developer, as silver halide complexing agents alkali metal sulphite salts in an amount from 1 to 50 g per litre, at least 1 g of a compound corresponding to the formula (I), a precursor thereof, a derivative thereof and/or a metal salt thereof <CHEM> wherein each of A, B and D independently represents an oxygen atom or NR<1>; X represents an oxygen atom, a sulphur atom, NR<2>; CR<3>R<4>; C=O; C=NR<5> or C=S; Y represents an oxygen atom, a sulphur atom, NR<'2>; CR<'3>R<'4>; C=O; C-NR<'5> or C=S; Z represents an oxygen atom, a sulphur atom, NR<''2>; CR<''3>R<''4>; C=O; C=NR<''5> or C=S; n equals 0, 1 or 2; each of R<1> to R<5>, R<'1> to R<'5> and R<''1> to R<''5>, independently represents hydrogen, subsituted or unsubstituted alkyl, aralkyl, hydroxyalkyl, carboxyalkyl; substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted cycloalkenyl, substituted or unsubstituted aryl or substituted or unsubstituted heterocyclyl; and wherein R<3> and R<4>, R<'3> and R<'4>, R<''3> and R<''4>, may further form together a ring; and wherein in the case that X=CR<3>R<4> and Y=CR<'3>R<'4>, R<3> and R<'3> and/or R<4> and R<'4> may form a ring and wherein in the case that Y=CR<'3>R<'4> and Z=CR<''3>R<''4> with n= 1 or 2, R<'3> and R<''3> and/or R<'4> and R<''4> may form a ring. Optionally said developer further comprises at least one thiocyanate salt in an amount from 0.1 to 3.0 g, and more preferably from 0.5 to 2.5 g per litre or a compound corresponding to the formula (II), accompanied by charge compensating anions, in amounts from 0.1 to 5 g and more preferably from 0.5 to 2.5 g per litre; <CHEM> wherein at least R or one of the ring substituents contains at least one oxyethylene group; or wherein R is a substituted or unsubstituted aliphatic or aromatic group and wherein Z' is composed of atoms to form a substituted or unsubstituted heterocyclic aromatic 5- or 6-ring.
