Appellant's claimed invention is directed to a composition
for dying keratin fibers comprising at least one of the recited
cationic direct dyes and at least one of the claimed cationic or
amphoteric substantive polymers. According to appellant's
specification, a first type of dyeing in the hair sector is semi-
permanent or temporary dyeing, also known as direct dyeing. A
second type is permanent or oxidation dyeing with "oxidation"
dyes comprising oxidation dye precursors and couplers. At the
time of filing the present application, it was a known practice
to vary the shades obtained with oxidation dyes by adding direct
dyes thereto. Known cationic direct dyes have the disadvantage
of leading to insufficient colorations, both regarding the
homogeneity of the color distributed among the fiber and the
staying power. Appellant's specification relates that:
Now, after considerable research conducted in this
area, the Inventor has discovered that it is possible
to obtain novel compositions for dyeing keratin fibers
capable of giving colorations that are less selective
