摘要:The present invention is concerned with a method of synthesizing certain ##STR1## 3-disubstituted sulfam(na)phthalein compounds useful as pH-sensitive indicator dyes and with intermediates useful in the preparation of said compounds. The subject method comprises (1) reacting (a) a 3,3-disubstituted sulfam(na)phthalein wherein one of the 3-substituents is a 4'-hydroxy-1'-phenyl moiety or a 4'-hydroxy-1'-naphthyl moiety substituted in the 3'-position with a perhalomethylcarbinol group and (b) an acid halide, ##STR2## wherein R is alkyl or aryl to give (c) an acylated intermediate wherein the N atom of the sulfam(na)phthalein ring and the 4'-hydroxy and carbinol hydroxy groups are acylated with ##STR3## and (2) treating said compound (c) with alkali to selectively remove said ##STR4## from said hydroxy groups and yield the ##STR5## product. The intermediates of the present invention are the acylated compounds (c).

摘要:A toner for electrostatic charge developing prepared by a production method including aggregating one or more kind of particles in a raw material dispersion including the particles to form aggregated particles, and coalescing the aggregated particles by heating. At least one kind of the particles is resin particles including an amorphous polyester resin synthesized by copolymerizing one or more polyvalent carboxylic acids and two or more polyhydric alcohols; at least one of the polyvalent carboxylic acids is polyvalent carboxylic acid having a sulfonic acid group; two of the polyhydric alcohols are an ethylene oxide adduct of bisphenol A and a propylene oxide adduct of bisphenol A; and the following equation is satisfied:n n10/90≦ BPA ( EO )/ BPA ( PO )≦90/10.n n In the equation, BPA(EO) represents a total mole amount of the ethylene oxide adduct of bisphenol A used in synthesis of the amorphous polyester resin, and BPA(PO) represents a total mole amount of the propylene oxide adduct of bisphenol A used in synthesis of the amorphous polyester resin.
