FIELD: polygraphic industry.
SUBSTANCE: ink for jet printing is described including water, watersoluble organic solvent and coloring substance which is phthalocyanine compound. Content of specified coloring substance is in the range of 0.5 wt % ≤ content < 3.0 wt % relative to ink weight. Watersoluble organic solvent includes 2-pyrrolidone in amount of 50.0% or more relative to ink weight. Value of dispersion distance d75, measured using small angle X-ray scattering method for molecular aggregates in ink corresponds to 75% of dispersion distance distribution. Suggested ink is high resistant to ambient gases, to coloring substance aggregation and provides bronze play-resistant images.
EFFECT: getting ink that is high resistant to ambient gases, to coloring substance aggregation and provides bronze play-resistant images.
