Description

Trisazo dye, composition and ink jet printing method

The present invention relates to compound, relate to composition and their purposes in press, is not only ink jet printing (" IJP ") especially.IJP is a kind of wherein ink droplet by thin nozzle ejection on matrix and do not make the nonimpact printing technology on nozzle and matrix basis.

For dyestuff that is used for IJP and printing ink, there is the performance requirement of multiple expectation.For example, expect that they provide the image of sharp, the non-plumage traceization with good absorbancy, water tolerance, light resistance are provided and in the presence of oxidizing gas pollutent (for example ozone), resist and fade.In the time of on being applied to matrix,, need printing ink dry rapidly usually, but the tip that they are not taken in injection nozzle form duricrust, because this will stop printer work in order to prevent to blur.Printing ink is storage-stable for a long time also, can not decompose or form the precipitation that may block thin nozzle.

JP10195320 has described the trisazo dye that has the pyrazolyl azo group and they application in paper and paper pulp are painted.
