Toner preparation processes |
| abstract |
A process for the preparation of toner comprising blending an aqueous colorantndispersion and a latex emulsion containing resin; heating the resulting mixture at antemperature below about the glass transition temperature (Tg) of the latex resin to formntoner sized aggregates; heating said resulting aggregates at a temperature above aboutnthe Tg of the latex resin to effect fusion or coalescence of the aggregates; redispersingnsaid toner in water at a pH of above about 7; contacting the resulting mixture with a metalnhalide or salt, and then with a mixture of an alkaline base and a salicylic acid, a catechol,nor mixtures thereof at a temperature of from about 25°C to about 80°C; and optionallynisolating the toner product, washing, and drying. |
