| titleOfInvention | Triarylmethane leuco compound and composition comprising the same |
| abstract | A composition comprising a plurality of triarylmethane leuco molecules. The triarylmethane leuco molecules include a first alkyleneoxy moiety and a second oxyalkylene moiety, and the mass distribution of the first alkyleneoxy moiety is different from the mass distribution of the second alkyleneoxy moiety. Triarylmethane leuco compounds have formula (C). The composition contains a plurality of triarylmethane leuco molecules, and about 5 mole% or more of the triarylmethane leuco molecules are present in the composition including the first alkyleneoxy moiety, which does not contain At least one of the alkyleneoxy repeating units in the alkyleneoxy moiety. A method for preparing a triarylmethane leuco compound, comprising the steps of: (a) providing an aromatic aldehyde compound; (b) providing a first oxyalkylene aryl compound; (c) providing a second oxyalkylene An aryl compound, wherein the second oxyalkylated aryl compound is different from the first oxyalkylated aryl compound; (d) providing an acidic catalyst; and (e) making the aromatic aldehyde compound, the first oxygen The alkylene compound and the second oxyalkylene compound are reacted in the condensation reaction in the presence of an acidic catalyst to produce a triarylmethane leuco compound. |
