APPENDIX 2
Claims 1-29 of Lagrange Patent 5,178,637:
1. A tinctorial composition useful for dyeing keratinous fibres, in particular
human keratinous fibers, comprising from 0.01 to 8% by weight, relative to the
total weight of the composition, of at least one 5,6-dihydroxyindoline
corresponding to the formula (I):
HO
CH2
CH2 (I)
HO N
R
in which R represents a hydrogen atom or a C1-C4 alkyl group, or an

dyeing is an aqueous medium of water or a water/solvent mixture.
4. A composition according to claim 3, wherein the solvent is ethyl
alcohol, propyl alcohol, isopropyl alcohol, tert-butyl alcohol, ethylene glycol,
ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene
glycol monobutyl ether, ethylene glycol monoethyl ether acetate, propylene
glycol, propylene glycol monomethyl ether, dipropylene glycol monomethyl ether
or methyl lactate.
5. A composition according to claim 1, wherein the composition contains
a fatty amide, anionic, cationic, nonionic or amphoteric surfactant, or a mixture
thereof, thickener, perfume, sequestering agent, film-forming agent, treatment
agent, dispersing agent, conditioner, preservative, opacifying agent or agent for
