    摘要： IN WHICH X represents an oxygen or sulfur atom, Y represents

    Valuable benzoxanthene and benzothioxanthene dyestuffs of the general formula

    D R A W I N G
    GROUPS, WHEREIN R stands for a hydrogen atom or an alkyl, cycloalkyl or aryl group which may be substituted, a heterocyclic radical, a hydroxyl or amino group, R1 and R2 each represent hydrogen atoms, halogen atoms, especially chlorine or bromine atoms, alkyl or alkoxy groups, and n stands for a number of 1 to 3, which dyestuffs are suitable for dyeing and printing of plastic materials and excellently suitable as fluorescing dyestuffs in the dyeing of condensation resins which when dyed are distinguished by excellent fastness to bleeding and good fastness to light.

    摘要： Dyestuffs consisting of the mixture of isomers of the formulae
    wherein R5 and R6 are hydrogen, alkyl or hydroxyalkyl with 1 to 4 carbon atoms or phenyl, or together are piperidine, morpholine or piperazine. The new dyestuffs are very suitable for the dyeing of synthetic materials such as polyethylene-glycol terephthalate, acetyl cellulose or polyamides. They yield brilliant greenish yellow to orange red shades which have a good fastness to light and to thermofixation. They are also very suitable for the dyeing of fibre-forming polymers such as for example polyethylene-glycol terephthalate in the mass. Furthermore, a big part of the dyestuffs can be used for dyeing synthetic fibre materials such as polyester fibers from organic solvents, for example perchloroethylene.

    WHEREIN R1 is hydrogen, alkyl with 1 to 20 carbon atoms, alkoxyalkyl or alkoxycarbonyl each with up to 4 carbon atoms, benzyl, alkoxycarbonyl with up to 20 carbon atoms or phenyl, R2 is alkoxycarbonyl with up to 20 carbon atoms, cyano, alcanoyl, alkoxyalkoxycarbonyl each with up to 4 carbon atoms, carbonamido, phenylcarbonamido, mono- or dialkylcarbonamido with up to 8 carbon atoms or cyclohexylcarbonamido, R3 and R4 are identical and are hydrogen or alkoxy with 1 to 4 carbon atom atoms or R3 is alkoxy with 1 to 4 carbon atoms and R4 is hydrogen and R is phenylthio which may be substituted by one or two chlorine or bromine atoms, alkyl, alkoxy, carbalkoxy, alkylsulfonyl groups and with up to 4 carbon atoms or a cyano, trifluoromethyl or nitro group; naphthylthio, pyridinethio, benzimidazolyl-2-thio, benzoxazolyl-2-thio, benzthiazolyl-2-thio or an amino group of the formula
