1. : an orange or red crystalline compound C 14 H 6 O 2 (OH) 2 formerly prepared from madder and now made synthetically from anthraquinone that with different mordants produces on cotton the Turkey reds and other shades (as pink and chocolate) but that is used now more in making red pigments than in dyeing; 1,2-dihydroxy-anthraquinone — see dye table I (under Mordant Red 11 )
2. : any of a group of acid, mordant, and solvent dyes derived like alizarin proper from anthraquinone and used to produce various hues — see dye table I
