Appeal No. 2006-2423 Page 2
Application No. 10/297,871
Background
The application provides methods for coloring keratin fibers in which at least one
pyridoxine, pyridoxal, or pyridoxamine derivative of a formula (I) is used in combination
with an oxidation dye precursor. Specification, page 1, lines 1-4; page 4, line 23;
page 5, line 10. The formula (I) compounds are used as a component in hair colorants
to produce a “medium blond” color. Id., page 4, lines 16-20. In addition, it was found
that the “use of these compounds . . . during the coloring process leads to an
improvement in the structure of keratin.” Id., page 4, lines 20-22.
Claims
Claims 24-30, 33-35, and 47 are appealed. Claims 33-35, 37-40, and 47 are
directed to compositions; claims 24-30 are to methods of using the compositions to
color hair. Each grouping has only one independent claim, 47 and 24 respectively. The
claims read as follows:
24. In process for coloring keratin fibers, more particularly human hair, in which:
optionally, a pretreatment preparation is applied to the fibers,
a colorant M2 is then applied to the fibers, optionally having been mixed
immediately before application to the fibers from:
a component M2a containing at least one oxidation dye precursor
of the primary intermediate type and/or an indole and/or indoline
derivative and
a component M2b containing an oxidizing agent and/or an enzyme,
the colorant M2 being rinsed off the fibers after a contact time of from 5 to
30 minutes,
