Appeal No. 96-1675
Application No. 08/317,977
method of developing an imagewise exposed color photographic
element by using appellant's compositions described above.
Claims 1 and 12 are reproduced below for a more facile
understanding of the appealed subject matter.
1. An aqueous redox amplifier composition
comprising a colour developing agent, hydrogen
peroxide or a compound which provides hydrogen
peroxide and hydroxylamine or a salt thereof wherein
the concentration ranges are:
hydrogen peroxide from 0.5 to 10 ml/l (as
30% w/w solution),
hydroxylamine or a salt thereof from
0.25 to 5.5 g/l (as hydroxylamine sulphate), and
wherein the pH is in the range
of from 11 to 12.
12. A method for
processing an imagewise exposed color photographic
element comprising contacting said element with an
aqueous redox amplifier composition comprising a
colour developing agent, hydrogen peroxide or a
compound which provides hydrogen peroxide and
hydroxylamine or a salt thereof wherein the
concentration ranges are:
hydrogen peroxide from 0.5 to 10 ml/l (as 30%
w/w solution),
hydroxylamine or a salt thereof from 0.25
to 5.5 g/l (as hydroxylamine sulphate), and
wherein the pH is in the range
of from 11 to 12.
