Appeal No. 2002-2036
Application 09/486,558
a. they must contain at least one of the compounds of the
formula (I);
b. they must contain a paraphenylenediamine or a
paraaminophenol or a heterocyclic oxidation base such
as 2,5-diaminopyridine or 2-hydroxy-5-aminopyridine
[emphasis added];
c. they can contain, in addition to coupler (I), other
known couplers such as: resorcin, metaaminophenol,
2,4-diaminoanisole, 7-hydroxyphenomoropholine, 2-
methyl-5-ureidophenol, 2,6-dimethyl-5-aminophenol, 2-
methyl-5-acetylaminophenol, 3-amino-4-methoxy-phenol,
and the pyrazolones;
d. they can contain several oxidation bases [emphasis
added];
e. they can also contain dyes in the form of
leucoderivatives, in particular diphenylamines
substituted in the 4 and 4 position by NH2 or OH
groups as well as other various substituents on the
two benzene rings, which diphenylamines on oxidation
produce indamines, indoanilines or indophenols;
f. they can also contain direct dyes such as azo dyes,
anthraquinones, nitribenzene dyes, indamines,
indoanilines or indophenols; and
g. they can be utilized in the form of an aqueous or
hydroalcoholic solution containing a lower alkanol,
preferably ethanol or isopropanol.”
Therefore, Kalopissis’ dye composition can contain, inter
alia, (b) a heterocyclic oxidation base such as 2,5-
diaminopyridine or 2-hydroxy-5-aminopyridine and (d) several
oxidation bases.
Hence, there is a proper foundation found in Kalopissis to
add additional oxidation bases to the dye composition of
Kalopissis. The examiner relies upon Clausen for the teaching of
