标题:Process for the purification of triphenylmethane compounds
发明人：FLORES ROBERT J
权利人:PMC SPECIALTIES GROUP INC
摘要:Triphenylmethane dyes are obtained in a purified or more concentrated condition which eliminates the excess aromatic amines and by-products obtained during the synthesis of the triphenylmethane dyes. These purified triphenylmethane dyes show special utility when used in combination with an electron acceptor (Lewis acid) to produce carbonless copy paper or when used as reactants in the manufacture of other dyes.
