    The composition of printing ink of 1. ability in swimming reachs function

    Printing ink of ability in swimming basically is worth composition of additive of etc of conditioning agent, drier by activator of solvent, colorant, surface, PH, to hot pressing type ink-jet printing system, can choose printing ink of ability in swimming only; Press needing ink-jet printing printing ink also is to use printing ink of ability in swimming normally. 

   (1) colorant

Be like dye of Kun of dye of content of complexing of azo dyes, metal, naphthol dye, anthracene, indigotic dye, Kun inferior amine dye, Jing dye, quinoline dye, nitro- dye, inferior dye of Jing of dye of Kun of dye of Kun of nitro- dye, benzene, naphthalene, phthalein or dye of metallic phthalein Jing, special actor chooses dye of oily dissolve sex. 

    For the printing ink of ability in swimming to be colorant with dye, as a result of dye not agent of dissolve Yu Rong, assure its to reach the effect that deliver quality to still need other part and higher technical demand in the dispersive stability in solvent so. Painty cent is have inorganic pigment and organic pigment, include carbon black, chromium red, molybdenum is red, chromic chromium of yellow, oxidation, Wei Lidi installs yellow, titanium painty, titanium is cobaltic green, ultramarine is blue, cobaltic pyrrole of blue, 2 ketone Kun of pyrrole, anthracene, and occasionally nitrogen kind, phthalein Jing kind, person forest kind, indigo of purple perilla ketone, sulfur kind, Kui phthalein ketone or dye of metallic complexing content. 

    Dye or dye can be used alone, also but will 2 plant or the dye of 2 kinds of above or dye combination are used, the average diameter of painty particle had better be 50 ～ 500nm, its content basis printing ink utility or presswork characteristic and proper choice, the 1 ％ ～ that is printing ink gross weight 10.0% .
