(US5755875-A)      Perylenecarbamide, quinacridone, isoindoline, indigoid, azo, benzodipyrrolone, benzodifuranone, furanofuran, pyrrolo(2,5-b)pyrrole and bianthraquinone chromophore cpds (I) contg gp(s). of formula (II) are new.    In (II): A = N-CN in at least one case, otherwise O; X = -N(R)-, -O- or -S-; R =H; 1-18C alkyl; phenyl opt. substd by halogen or 1-4C alkyl, benzyl or phenethyl; and m, n = 0 or 1.    Also claimed is high mol. organic material contg (I).    USE -   (I) are used as polymer-soluble dyes for e.g. polystyrene, polyamides, ABS and esp. linear polyesters or pigment for other materials, e.g. natural resins, drying oils, rubber, casein, chloro-rubber, oil-modified alkyd resins, viscose, cellulose ethers or esters and esp. synthetic thermosetting and thermoplastic resins such as polyolefins and (co)polymers of vinyl chloride, vinyl acetate, styrene, acrylonitrile, (meth)acrylic esters and/or butadiene esp. EVA, including fibres, lacquers or printing inks. (I) are also useful as electro- and magnetrographic toners, in inks, esp. for ink jet and security printing, in solar energy collectors and laser systems, as organic photoconductors for copiers and laser printers and as active components of electroluminescent units.    ADVANTAGE -   (I) have unexpectedly high solid state fluorescence. They can be prepd. by converting a wide range of mainly readily available, high-grade pigments contg. oxo gp(s). into the corresp. cyan-imino derivs. which causes an interesting bathochromic shift.
