Abstract: THE INVENTION RELATES TO ANTHRANILIC ACID ESTERS WHICH ARE ALKYLATED IN THE NUCLEUS REPRESENTED BY THE GENERAL FORMULA

2-(RO-CO-),3-(H2N-),((4-R1,R2,R3-PHENYL)-Z-)-ANTHRACENE

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
