Appeal No. 2003-0615
Application No. 09/319,165
color stability to washing, light and weather is a characteristic
of the coupler (col. 3, lines 4-10). Hence, Andrillon would have
fairly suggested, to one of ordinary skill in the art, obtaining
color stability in Yamahatsu’s dye composition by using, in
combination, 2-methyl-5-N-($-hydroxyalkyl)aminophenol, a para-
phenylenediamine and a para-aminophenol.
For the above reasons we conclude that the appellants’
claimed invention would have been obvious to one of ordinary
skill in the art over Yamahatsu in view of Andrillon.
Rejection over Andrillon in view of Tsujino
Tsujino discloses a hair dye composition comprising a
dielectron reducing oxidase enzyme, a donor for the enzyme, and
an ordinary oxidation dye (col. 1, lines 49-54; col. 2, lines 4-
10 and 45-46). The disclosed oxidation dyes include a number of
para-phenylenediamines and addition salts thereof (the
appellants’ first oxidation base), a number of para-aminophenols
and acid addition salts thereof (the appellants’ second oxidation
base), and 5-(2-hydroxyethylamino)-2-methylphenol (the
appellants’ coupler, 2-methyl-5-N-($-hydroxyethyl)aminophenol)
