Abstract: Disclosed are nitro-sulfide dyes of formula (1) , their salts, isomers, hydrates and other solvates, wherein R<sub>1</sub>, R<sub>2</sub>, R<sub>3</sub>, independently from each other are hydrogen; C<sub>1</sub>-C<sub>20</sub>alkyl or C<sub>1</sub>-C<sub>20</sub>alkoxy, which may be substituted by one or more C<sub>1</sub>-C<sub>5</sub>alkoxy, halogen, -NH<sub>2</sub>, mono-C<sub>1</sub>-C<sub>5</sub>alkylamino, di-C<sub>1</sub>-C5alkylamino, -NO2 or hydroxy; C<sub>3</sub>-C<sub>6</sub>cycloalkyl; -C(O)H; -C(O)-C<sub>1</sub>-C<sub>5</sub>alkyl; -C(O)OH; -C(O)O-C<sub>1</sub>-C<sub>5</sub>alkyl; halogen; NO<sub>2</sub>; OH; SH; phenyl, which may be substituted by one or more C<sub>1</sub>-C<sub>5</sub>alkyl, C<sub>1</sub>-C<sub>5</sub>alkoxy, halogen, -NH<sub>2</sub>, mono-C<sub>1</sub>-C<sub>5</sub>alkylamino, di-C<sub>1</sub>- C<sub>5</sub>alkylamino, -NO<sub>2</sub> or hydroxy; or a radical of formula (1a) -NR<sub>4</sub>R<sub>5</sub>, wherein R<sub>4</sub> and R<sub>5</sub> independently from each other are hydrogen; C<sub>1</sub>-C<sub>12</sub>alkyl, which may be substituted by one or more C<sub>1</sub>-C<sub>5</sub>alkyl, C<sub>1</sub>-C<sub>5</sub>-alkoxy, hydroxy or -(CO)-H; -(CO)-C<sub>1</sub>- C<sub>5</sub>alkyl; phenyl or phenyl-C<sub>1</sub>-C<sub>4</sub>alkyl, wherein the phenyl moiety may be substituted by one or more C<sub>1</sub>-C<sub>5</sub>alkyl, C<sub>1</sub>-C<sub>5</sub>alkoxy, halogen, -NH<sub>2</sub>, mono-C<sub>1</sub>-C<sub>5</sub>alkylamino, di-C<sub>1</sub>-C<sub>5</sub>alkylamino, -NO<sub>2</sub>, carboxy or hydroxy; or a radical of formula (2); wherein at least one of the radicals R<sub>1</sub>, R<sub>2</sub> or R<sub>3</sub> is NO<sub>2</sub>; Y<sub>1</sub> is C<sub>1</sub>-C<sub>10</sub>alkylene; C<sub>5</sub>-C<sub>10</sub>cycloalkylene; C<sub>5</sub>-C<sub>10</sub>arylene; or C<sub>5</sub>-C<sub>10</sub>arylene-(C<sub>1</sub>-C<sub>10</su b>alkylene); Z1 is the direct bond; formula (3) ; or a cationic biradical of a saturated, aromatic or heteroaromatic group; Q<sub>1</sub> is -C(O)-; --C(O)O-; -OCO-; -N(R<sub>6</sub>)-X<sub>2</sub>-; -CON(R<sub>6</sub>)-; -(R<sub>6</sub>)NC(O)-; -O-; -S-; -S(O)-; or -S(O)<sub>2</sub>-; X<sub>1</sub> and X<sub>2</sub> independently from each other are the direct bond; C<sub>1</sub>-C<sub>10</sub>alkylene; C<sub>5</sub>- C<sub>10</sub>cycloalkylene; C<sub>5</sub>-C<sub>10</sub>arylene; or C<sub>5</sub>-C<sub>10</sub>arylene-(C<sub>1</sub>-C<sub>10</su b>alkylene); and R<sub>6</sub>, R<sub>7</sub> and R<sub>8</sub> independently from each other are hydrogen; C<sub>1</sub>-C<sub>14</sub>alkyl; C<sub>2</sub>-C<sub>14</sub>alkenyl; C<sub>6</sub>- C<sub>10</sub>aryl; C<sub>6</sub>-C<sub>10</sub>aryl-C<sub>1</sub>-C<sub>10</sub>al kyl; or C<sub>1</sub>-C<sub>10</sub>alkyl(C<sub>5</sub>-C<sub>10</sub>a ryl); m is 1; or 2; U is hydrogen, if m is 1; or the direct bond, if m is 2; with the proviso that the method does not comprise contacting hair with an enzyme of the type of a protein disulfidisomerase (EC 5.3.4.1). Further, the present invention relates to novel sulfide compounds, compositions thereof, especially comprising other dyes, and to processes for their preparation.
