Patent Interference No. 103,548
APPENDIX 1
Claims 1-14 of Konrad Application 07/949,851:
1. A process for oxidative dyeing of keratin fibers by contacting said keratin
fibers with a dyeing composition comprising a carrier and indolines, or salts of
indolines, corresponding to formula I:
R3
R4O
R2 (I)
R5O N
R1
in which R1, R2, R3, R4, and R5 independently of one another represent hydrogen
or C1-4 alkyl groups, or R4 and R5 together with the oxygen atoms to which they
are attached may represent an alkylenedioxy group containing 1 to 4 carbon
atoms, and causing oxidation of said dye-ing composition while it is in contact
with said keratin fibers.
2. A process as claimed in claim 1, wherein, in formula I, the groups R1, R2,
R3, R4, and R5 are hydrogen, except that one of the groups R1, R2, and R3 may
be a methyl group.
3. A process as claimed in claim 2, wherein the indolines corresponding to
formula I or salts thereof are used as color modifiers in oxidation hair dyes
containing other aromatic or heterocyclic amino primary intermediate
compounds.
4. Hair dyes comprising oxidation dye precursors in a carrier, wherein
indolines, or salts of indolines, of formula I:
R3
R4O
R2 (I)
R5O N
R1
in which R1, R2, R3, R4, and R5 independently of one another represent hydrogen
or C1-4 alkyl groups, or R4 and R5 together with the oxygen atoms to which they
