Abstract
The invention comprises dyes of the formula <FORM:0967178/C4-C5/1> in which R1 and R2 are each a straight or branched chain alkyl or alkenyl group having more than 3 carbon atoms or a cycloalkyl group, and in which the perylene residue may be substituted by halogen atoms. The dyes are made by reacting at least one amine chosen from saturated or unsaturated straight chain or branched chain primary aliphatic amines of more than 3 carbon atoms and cycloaliphatic amines either with perylene-3 : 4 : 9 : 10-tetracarboxylic acid or a halo-derivative thereof or the corresponding anhydride, or with naphthalene-1 : 8-dicarboxylic anhydride or a halo-derivative thereof when the resulting N-substituted - 1 : 8 - naphthalene - dicarboxylic acid diimide is melted with an alkali-metal hydroxide. The dyes are fluorescent red to orange pigments for polystyrene.
