Ar Benzol der Naphthalin,
X -CH₂-CH₂- und/oder -CH₂-CH(CH₃)-,
0 bis (m-1) der Reste A Wasserstoff,
1 bis m der Reste A Benzoyl und/oder Naphthoyl,
1 bis m der Reste A -CO-CH=CH-COOM und/oder -CO-CH₂-CH(SO₃M)-COOM sind, wobei M für ein Kation steht,
R¹,R² und R³ Wasserstoff oder Alkyl mit 1 bis 14 C-Atomen,
R Wasserstoff und/oder Alkyl mit 1 bis 9 C-Atomen,
n eine Zahl von 1 bis 150 und
m eine Zahl von 2 bis 12 bedeuten,
und worin das Pigment eine durchschnittliche Korngröße von 50 bis 500, vorzugsweise 80 bis 300 nm aufweist. Durch die Verwendung dieser Dispersionen, die die Pigmente in sehr feinteiliger Form enthalten, erreicht man eine gute Durchfärbung des Leders mit verbesserter Lichtechtheit. of the formula (I) in which
Ar benzene the naphthalene,
X -CH₂-CH₂- and / or -CH₂-CH (CH₃) -,
0 to (m-1) of the radicals A are hydrogen,
1 to m of the residues A benzoyl and / or naphthoyl,
1 to m of the radicals A are -CO-CH = CH-COOM and / or -CO-CH₂-CH (SO₃M) -COOM, where M is a cation,
R¹, R² and R³ are hydrogen or alkyl having 1 to 14 carbon atoms,
R is hydrogen and / or alkyl having 1 to 9 carbon atoms,
n is a number from 1 to 150 and
m is a number from 2 to 12,
and wherein the pigment has an average grain size of 50 to 500, preferably 80 to 300 nm. By using these dispersions, which contain the pigments in a very fine-particle form, the leather is well colored with improved lightfastness.
