FIELD: chemistry.SUBSTANCE: claimed invention relates to a method of obtaining toner particles. Described are versions of the method realisation, including mixing in the melt of amorphous polyether resin, obtained from a biological raw material, optionally crystalline resin, optionally wax and optionally dye with obtaining a toner; granulation of the toner with obtaining toner granules; optional annealing of the toner granules; grinding the toner granules with obtaining the toner particles; contact of the toner particles with deionised water and at least one surface-active substance with obtaining a mixture, coalescence of the toner particles by heating the mixture to a temperature from about 50°C to about 100°C with mixing the mixture at the rate from about 50 revolutions per minute to about 500 revolutions per minute from about 0.1 hour to about 9 hours at pH from about 6 to about 10, and the separation of the toner particles from the mixture, where the separated toner particles have the circularity from 0.92 to about 0.999.EFFECT: obtaining the toner particles, possessing desirable sphericity.19 cl, 4 tbl, 1 ex |
