Abstract

Water-insoluble dyes have general formula (I) or (II) (in which X is O or S; R1 and R2 denote H, C2H5, an acyl or alkoxy gp.; R3-8 denote H or non-ionogenic substituents; with the proviso that two adjacent R's may form an aromatic or heteroaromatic ring). These cpds. can be produced e.g. by internally cyclising the corresp. diazonium salts (to form the ring contg. X) These dyes are suitable for cellulose acetate, polyester, or polyamide textiles, articles made from polystyrene, polymethyl methacrylate, PVC, polycarbonates, polyethylene, polypropylene and superpolyamides, and for the prodn. of pigments for lacquers or printing pastes. Bright, clear, fluorescent yellow to red colours fast to light, heat sublimation, etc, are obtained.
