FIELD: chemistry.
SUBSTANCE: invention relates to novel azo compounds intended for jet recording. Disclosed is an azo-compound of formula (1), its tautomer or salt of azo compounds or tautomer, where R1 -(C1-C4) alkyl or similar group; R2 - cyano group or similar group; R3 and R4 -hydrogen, sulpho, (C1-C4) alkoxy or similar group; R5 and R7 -(C1-C4) alkylthio or similar group; R6 and R8 -(C1-C4) alkylcarbonylamino group; R9 and R10 -(C1-C4) alkoxy or similar group; R11-R13 -hydrogen, sulpho group or similar groups. Also disclosed are a composition of ink, method for jet recording using same, a jet printer and coloured material.
EFFECT: disclosed dye has high gas resistance, particularly high ozone resistance, high printing density, low colour, low colour saturation and high-quality black colour when recording on paper.
