摘要:
Concentrated, liquid preparations of metal-free direct azo dyes, which contain in each instance 1 part by weight of dye, 1 to 8 parts by weight of water, and 0.5 to 5 or preferably 0.5 to 2 parts by weight of an amide are useful for dyeing paper in the stock and for dyeing paper sheet.
摘要:
The present invention provides a trisazo dye represented by the formula: ##STR1## [wherein A is a phenyl group substituted with at least one substituent selected from the group consisting of an amino group, a substituted amino group and a hydroxyl group, B is a substituted or non-substituted phenyl group, X is a group of the formula: ##STR2## Q is a group of the formula: ##STR3## (wherein n is 1 or 2), and M is hydrogen, alkali metal, aliphatic alkyl ammonium or alkanol ammonium]. An aqueous ink composition and a process for the producing a concentrated solution containing the trisazo dye are also disclosed.
摘要:
A recording liquid composition for use in a recording system of the type in which the recording liquid composition is jetted from a small orifice in a form of droplet flying toward a recording material on which an image is to be printed, said recording liquid composition comrising, as its recording agent component, a particular compound as well defined in the specification by the general formula (A) or (B).
