NEW MATERIAL:A compound shown by the formula I [X is H, or carboxylic acid (ester); Y is H, or alkoxy; with the proviso that when one of X and Y is H, the other is except H]. EXAMPLE:A compound shown by the formula II. USE:A dyestuff for coloring low-molecular substances such as mineral oil, liquid crystal, etc., and coloring natural-synthetic high polymer substances such as cellulose, cellulose acetate, polyester, etc. PREPARATION:A compound shown by the formula III (X<1> is H, or carboxylic acid; Z is halogen) is reacted with a compound (e.g., 2-amino-5-ethoxythiophenol, etc.) shown by the formula V, to give a compound shown by the formula I where the group X of the formula I is X<1>).
