FIELD: ink-jet printing facilities and materials. ^ SUBSTANCE: invention relates to ink-jet printing on sheet-shaped substrates such as paper, films, and textiles. In particular, invention discloses a method for ink-jet printing on sheet-shaped substrates using aqueous ink including (i) at least one dye of formula (I): (I), wherein R1 and R2, each independently of the other, represents hydrogen atom or unsubstituted or substituted C1-C4-alkyl; R3 and R4, each independently of the other, represents unsubstituted or substituted C1-C4-alkyl; R5 and R6, each independently of the other, represents C1-C4-alkyl, C1-C4-alkoxy, halogen atom, hydroxyl, carboxyl, C2-C4-alkanoylamino, or sulfo group; X represents halogen atom, hydroxyl, C1-C4-alkoxy optionally substituted in alkyl residue, phenoxy optionally substituted in phenyl residue, C1-C4-alkylyhio optionally substituted in alkyl residue, phenylthio optionally substituted in phenyl ring, amino, C5-C7-cycloalkylamino optionally substituted in cycloalkyl residue, phenyl- or naphthylamino optionally substituted in aryl residue, N-C1-C4-alkyl-N-phenyl- or N-C1-C4-alkyl-N-naphthylamino optionally substituted in aryl residue, benzylamino optionally substituted in phenyl residue, morpholine, or pyperidin-1-yl; and n and m each is a number 0, 1, 2, or 3; and (ii) compound selected from polyethylene glycols with molecular mass from 150 to 400. ^ EFFECT: enabled producing light-resistant and moistureproof prints with elevated saturation of color. ^ 12 cl, 1 tbl |
