    • 专利摘要:
    An ink for use in ink jet printers is provided. The ink contains a water soluble dye, a polyamine containing 6 or fewer nitrogen atoms per molecule, with the ink composition having a pH of 8 or below. The ink has improved waterfastness over an equivalent ink formulation without the polyamine additive.

    (54) PRINTING INKES The invention relates to the printing industry, namely to printing inks. Inks containing 0.512% by weight of direct and / or acid dyes selected from the group are available: chi-nolin yellow SSF, direct bright green CBM, yellow strong 5FLL, fastuzole blue; L) W, pontamine violet durable 4 BL , ploksin BP, purple purple 4 BL, luxol blue durable MBSN; 7.0% by weight wetter-diethylene glycol-monobutyl ether 0.0510% by weight nitrogen-containing polyethyleneimine compound and water — the rest is 1. A disadvantage of known inks is their instability at a pH below 8. Under these conditions, polyethylenimines are in the protonated state and interact with the negatively charged sulfo groups of dyes, causing their aggregation and the formation of clots. In addition, the primary amino groups in polyethyleneimines destroy dyes containing a30- () groups, after which the dye can also precipitate and form clots. The formed clots block thin nozzles in the inkjet printing device. The purpose of the invention is to increase the stability of ink to aggregation. The goal is achieved by printing inks containing direct and acid dyes, diethylene glycol monobutyl ether, nitrogen-containing compound and water, as dye containing direct orange and acid black, as a nitrogen-containing compound tetraethylenepentamine or permethylated tetraethylene pentamine in the following ratio of components, wt.%: For my orange1,5 Acid black7, O Diethylene glycol monobutyl ether7.0 Tetraethylenepentamine or permethyl tetraethylenepentamine 2.0 Water Ost Flax Use of Color Index dyes having numbers C.I. my orange is 72 and C.I. acid black 2.

    The pH value is set to a value of 7.0 with hydrochloric acid, l. Resistance: By aggregation, it was determined by counting particles with a size of more than 3 mm after 14 days old. no ink in hermetically sealed containers at 61 ° C. There were 70,000 such particles in 1, 2 to 300 in composition, Tetraethylenephenamine and permethylated tetraethylenepentamine are low molecular weight polyamines containing b or less nitrogen atoms and functional amino groups are not primary. Compounds are stable at pH below 8. These properties determine the ink's resistance to aggregation. , Invention: Ink for printing, containing direct and acid dyes, diethylene glycol monobutyl ether, nitrogen-containing compound and water, characterized in that, in order to increase the SUSTAINABILITY of ink to aggregation, they contain direct orange and acid as dyes. black, as a nitrogen-containing compound, tetraethylenepentamine or permethyl tetraethylenepentamine with the following ratio of components, wt.%: Direct orange 1.5 Acid black 7.0 Diethylene glycol 1-butyl ether 7.0 Tetraethylene ntamin or. .
