    Abstract: Synthetic, semi-synthetic or natural macromolecular substances are mass-dyed with a pigment dye of the formula wherein the anthraquinone radicals may contain as substituents halogen atoms, alkyl, CH3CO, C6H5CO, amino, OH or acylamino groups or benzoylamino groups which may bear halogen atoms or alkyl or alkoxy groups in the phenyl radical. Specified macromolecular substances are polyvinyl chloride, polystyrene, polyamides, polyethylene, polypropylene, polyesters, phenoplasts, aminoplasts and rubber. Examples are given in which polyvinyl chloride and a mixture comprising a stoving lacquer consisting of coconut alkyd resin and a ureaformaldehyde resin are coloured.ALSO:Inks, distempers and lacquers, are obtained by using a pigment dye of the formula wherein the anthraquinone radicals may contain as substituents halogen atoms, alkyl, acetyl, benzoyl, amino, OH or acylamino groups or benzoylamino groups which may bear halogen atoms or alkyl or alkoxy groups in the phenyl radical. The dyes are obtained by reacting a naphthalene-2,6-dicarboxylic acid chloride or bromide with an antraquinone compound which contains an acylatable amino group in the 1-position. Examples are given for the preparation of the dyes.

    Abstract: Amino derivatives of heterocycles, defined as quinazolines, or quinazolines, pyrimidines and 1,3,5-triazines containing an aryl radical, which heterocycles contain one or two in which R1 is hydrogen or aryl, R2 is morpholino or aryl, R3 is chlorine, morpholine, aryl, arylamino, R4 is morpholine, aryl, arylamino, and the carbocyclic rings in the above formulae may be chlorine or methoxy substituted. Specified diluents preferred are water miscible, e.g. aliphatic ketones, cyclic ethers such as dioxan, groupings and wherein the amino groups are attached to a carboxylic ring, are produced by hydrogenating the corresponding nitro derivatives in a solvent or diluent in the presence of Raney nickel catalyst and of tertiary amines or stoically hindered secondary amines, the amount of hydrogen absorbed being that required to convert a nitro into an amino group, the hydrogenation being preferably conducted at 10 DEG to 50 DEG C. Per se are claimed compounds of the general Formula I to VII: tetrahydrofuran, which may also contain water. Numerous detailed working examples of the process and named products are given. Specification 927,974 is referred to.
