    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: Dispersions containing (a) a pigment, (b) an oxalkylated novolak, (c) urea and/or a compound containing at least 2 long-chain aliphatic groups and which are connected via a bridge member containing ester and/or amide groups, and (d) water and/or agents retarding drying up, and, optionally, usual adjuvants, are useful for pigmenting natural or synthetic materials, especially aqueous systems containing cellulose ethers.

    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.

    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.
