    Abstract: 1326613 Colouring PVC FARBWERKE HOECHST AG 20 Aug 1970 [21 Aug 1969] 40134/70 Heading C3P [Also in Division C4] Polyvinyl chloride is coloured red in the mass by incorporating therein a monoazo pigment of formula wherein X 1 , X 2 and X 3 are a H or halogen atom or an alkyl or alkoxy group, R 1 is an alkyl, cycloalkyl or aralkyl group, R 2 is a H atom, an alkyl or alkenyl group, a cycloalkyl, aralkyl or an aryl group which may be substituted by a halogen atom or an alkyl, alkoxy CF 3 , alkanoylamino, benzoylamine, alkanoyl, benzoyl, phenoxy, alkoxycarbonyl, carbamoyl, sulphonamido or alkylsulphonmido group and R 3 is a H atom or an alkyl or alkenyl group and R 2 and R 3 may form a ring with the N atom (see Divisions C4-C5). In Example 1 polyvinyl chloride, a phthalate ester plasticizer, a pigment as above and TiO 2 were mixed on a roller device to give a yellowish red film.

    Abstract: Stable dispersions of solids, especially pigments, are obtained by distributing a solid having acidic groups on its surface in a liquid medium comprising an amine having at least one aliphatic chain of more than 5 carbon atoms, a non-ionic and/or an anionic surfactant having one or more aliphatic chains with a total of more than 5 carbon atoms and an organic water-miscible solvent. These dispersions are easily distributable in hydrophobic and in hydrophilic systems.

    Abstract: Dispersions of inorganic and organic pigments containing an alkylene oxide adduct on long-chain aliphatic amines and an anionic surfactant having an aliphatic radical of 3 to 40 carbon atoms can easily be distributed in hydrophilic and hydrophobic media and yield colorations of high tinctorial strength and purity of shade.

    Abstract: Stable dispersions of pigments are obtained by finely distributing inorganic and/or organic pigments in water and/or agents preventing or retarding the drying-up of the dispersions containing condensation products of aromatic hydroxy compounds and alkanals as well as surfactants, said condensation products and surfactants containing aliphatic carbon chains of more than 5 carbon atoms. The dispersions are compatible with hydrophilic and hydrophobic media.
