数据库记载的用途

Used as a paper dye, a metal chelating agent, and an additive to drugs and cosmetics; [CAMEO] Rhodamine dyes (aminoxanthenes) are xanthene dyes that are very important commercially. They are brilliant, blue-red, fluorescent dyes used as colorants in inks, paper, and plastics. Sulfonated derivatives are used as wool and polyamide dyes. Red fluorescent pigments are produced from Rhodamine dyes, and some of these are used as laser dyes. Rhodamine B is used to make pink fluorescent pigments. [Ullmann]
