<p>There are described composite ternary organic-inorganic pigments, substantially consisting of a binary inorganic titanium dioxide/aluminium hydroxide component, in an amount of from 70% to 95% by weight, the remaining organic component in an amount of from 5% to 30% by weight consisting of an organic dye selected from azoic and quinophthalonic compounds containing in their structure at least one carboxylic and/or sulphonic, substantially salified, acid function. There is also described a process for the preparation of such pigments. Such pigments may suitably find application in varnishing products, air hardening and stove-baked enamels, in the pigmentation of plastics materials, in inks, and in the printing of fabrics, using conventional techniques.</p> |
