| titleOfInvention | Triarylmethane leuco compounds and compositions comprising the same |
| abstract | This invention relates to a composition comprising a plurality of leuco triarylmethane molecules. The leuco triarylmethane molecules comprise a first alkyleneoxy moiety and a second oxyalkylene moiety, and the weight distribution of the first alkyleneoxy moiety is different from the weight distribution of the second alkyleneoxy moiety. The leuco triarylmethane compound corresponds to Formula (C). The composition according to the invention comprises a plurality of leuco triarylmethane molecules, wherein about 5 mol% or more of the triarylmethane leuco molecules present in the composition comprise a first alkyleneoxy moiety which contains none of the alkyleneoxy repeating units present in the second alkyleneoxy moiety The process for making the triarylmethane leuco compound comprises the steps of: (a) using an aromatic aldehyde compound; (b) using a first oxyalkylenated aryl compound; (c) using a second oxyalkylenated aryl compound, wherein the second oxyalkylenated aryl compound is different from the first; (d) use of an acid catalyst; and (e) reacting the aromatic aldehyde compound, the first oxyalkylenated compound and the second oxyalkylenated compound in a condensation reaction in the presence of the acid catalyst to obtain the triarylmethane leuco compound. |
