Abstract

A titanium dioxide pigment is rendered suitable for internally pigmenting polymeric materials by first coating with 0.25% to 10.00% by weight of a hydrous oxide of aluminium, titanium, silicon or zirconium or mixtures of two or more of these, and then with an organic compound of an alpha-hydroxy acid having the structure <FORM:0824509/III/1> where R is an alkyl or aryl radical, R1 is hydrogen, ammonium, alkali-metal, alkaline-earth metal, alkyl or aryl radical, and R11 is hydrogen, alkyl or aryl radical, the organic compound being dispersed on the surface of the coated pigment in amount from 0.2% to 5.0% by weight of the pigment. A pigment according to the invention may be prepared by calcining a titanium dioxide dihydrate, ball milling in the presence of a dispersing agent such as an alkali-metal phosphate or silicate, introducing the milled material into a tank and precipitating the desired hydrous oxides on the surface. A flocculating agent such as magnesium sulphate may also be present. The product is washed and then treated with the organic compound, for example by adding it directly to either the wet or the dry product. To ensure uniform distribution the organic compound may conveniently be dissolved in acetone, ethylene glycol n-butyl ether, diethylene glycol n-butyl ether, methyl ethyl ketone, acetonitrile or dimethylformamide, and the solution applied for example by spraying.ALSO:A pigment of improved dispersability in synthetic polymeric products consists of titanium dioxide coated with 0.25-10% of an hydrous oxide of aluminium, titanium, silicon, or zirconium or mixtures of two or more thereof, and then coated with a derivative of an alphahydroxy acid having the structure <FORM:0824509/IV (a)/1> where R is an alkyl or aryl radical, R1 is hydrogen, ammonium, an alkali or alkaline-earth metal, or an alkyl or aryl radical, and R11 is hydrogen or an alkyl or aryl radical, dispersed on the surface of the coated titanium dioxide in an amount from 0.2-5% by weight. Polymers may be pigmented by mixing them with an organic solvent and the pigment. Examples refer to mixing the pigment with a 15% solution of cellulose acetate or polyvinyl chloride in acetone, forming a layer on glass, and allowing the solvent to evaporate. The pigment may also be employed with plastisols and organosols. The manufacture of filaments from the pigmented polymers is referred to.
