Application No. 09/319,165
aminophenol, where the alkyl group has 1-4 carbon atoms, and
2) an oxidation dye which is a para-phenylenediamine, a para-
aminophenol, or an acid addition salt of the diamine or
aminophenol (col. 1, lines 7-11; col. 2, lines 18-68). In
examples 12, 13 and 18, the appellants’ coupler, 2-methyl-5-N-
($-hydroxyethyl)aminophenol, is used in combination with at
least one para-phenylenediamine or addition salt thereof and a
para-aminophenol or acid addition salt thereof. Andrillon
teaches that colors are accurately reproducible because of the
very great stability characteristics of the coupler, particularly
in an ammoniacal dye composition solution (col. 3, lines 7-10),
and that when the coupler is combined with both a para-
phenylenediamine and a para-aminophenol, a whole range of shades
can be obtained depending on the choice of the para-
phenylenediamine or para-aminophenol (col. 3, lines 16-21).
Andrillon does not disclose an enzyme. Instead, Andrillon uses
in his examples a conventional oxidizing agent such as hydrogen
peroxide or an aqueous solution of urea peroxide (col. 10,
lines 8-12).
