Abstract
L'invention a trait au domaine de la chimie tinctoriale. Elle concerne l'application de colorants trisazoïques, dont certains sont nouveaux, à la teinture de matières ou fibres contenant de l'azote, notamment du cuir, de préférence du cuir au chrome et du cuir semi-chrome ainsi que des cuirs du type tanné au végétal, tels que le cuir grainé ou le cuir velours. Les teintures obtenues se caractérisent par une bonne solidité au polissage et à la migration.
