摘要: Ultraviolet light absorbers with extremely low volatility are prepared by reacting 2,4-dihydroxybenzophenone and organic dihalides or diepoxides. The resultant compounds have the general formula WHERE R is a divalent radical. These may be used as carriers for dye, permitting internal coloring of polyester films fibers.
