Dispersion dye, the production and use thereof

A dye of the formula (I)

• wherein
• D is the residue of a diazo component;
• R1 is hydrogen, (C1-C6)-alkyl, (C1-C4)-alkoxy or halogen or combines with R2 to form the group —*CH(CH3)CH2C(CH3)2—, where the carbon atom marked by * is attached to the phenyl nucleus;
• R2 and R3 independently are hydrogen, (C1-C6)-alkyl, substituted (C1-C6)-alkyl, (C3-C4)-alkenyl or substituted (C3-C4)-alkenyl;
• R4 is —CHR5CN, —CHR6COR7 or —CH═CH2;
• R5 is hydrogen, (C1-C6)-alkyl or substituted (C1-C6)-alkyl;
• R6 is hydrogen, (C1-C6)-alkyl or substituted (C1-C6)-alkyl;
• R7 is (C1-C6)-alkyl, substituted (C1-C6)-alkyl, vinyloxy, (C1-C6)-alkoxy, substituted (C1-C6)-alkoxy, phenoxy, substituted phenoxy, phenyl or substituted phenyl;
• and
• L is (C2-C6)-alkylene, oxygen-interrupted (C2-C6)-alkylene, (C2-C6)-alkenylene, arylene or substituted arylene;
• with the proviso that L is not C2-alkylene when R5 is hydrogen.
