Abstract: The production of perylene-3,4-dicarboxylic acid imines of formula (I) (R is hydrogen, C1-C8 alkyl, C5-C8 cycloalkyl, possibly substituted phenyl or naphthyl; the radicals R are mutually independently hydrogen, C1-C18 alkyl, possibly substituted aryloxy, arylthio, hetaryloxy or hetarylthio), in which the corresponding perylene-3,4,9,10-tetracarboxylic acid or its anhydride (II) is reacted under pressure with an amide of formula (III) R -CO-NHR (R is C1-C4 alkyl or -NR R , in which R and R are mutually independently hydrogen or one of the alkyl, cycloalkyl, phenyl or naphthyl radicals R and where, if more than one of the radicals R , R and/or R is not hydrogen, these radicals have the same meaning) in the presence of an inert diluent and a transition metal catalyst.

Abstract: Process for the bulk colouring of paper with pigments and fixing agents, where the pigment and the fixing agent are added simultaneously to the paper mass to be coloured and a cationic fixing agent is used as the fixing agent in a quantity of 0.01 to 3.0% by weight, based on the dry paper mass to be coloured.

Abstract: High-hiding calcium color lakes, possessing great full-shade brilliance and improved lightfastness, of the general formula where D is a radical of the formula in which (1) a predominant proportion of primary particles has one or more dimensions greater than 0.3 mu m, (2) the length/width ratio of the predominant proportion of primary particles is not less than 2:1 and for which (3) the lightfastness of polyethylene containing 0.05% of colorant, and of plasticized PVC containing a 1:10 reduction of colorant, is rated at least 5 on a blue scale with ratings of from 1 to 8. The lakes are particularly suitable for coloring plastics.

Abstract: A process for preparing perylene-3,4:9,10-tetracarboxylic dianhydride, comprising: dimerizing a naphthalene-1,8-dicarboximide of the formula IIa; reoxidizing the resulting alkali metal salt of the leuco form of the perylene-3,4:9,10-tetracarboxylic diimide of the formula Ia; hydrolyzing the diimide to the tetraalkali metal salt of perylene-3,4:9,10-tetracarboxylic acid in the presence of an inert organic solvent, of an alkali metal base and of water; and subjecting the tetraalkali metal salt of perylene-3,4:9,10-tetracarboxylic acid to the action of an aqueous inorganic acid to convert it into perylene-3,4:9,10-tetracarboxylic dianhydride; wherein R3 is cyclohexyl or phenyl which may each be substituted by up to three C1-C4-alkyl radicals, and the dimerizing is in a substantially homogeneous reaction medium consisting essentially of an apolar aprotic organic solvent and an alkali metal base.
