A process for the production of a particle composition containing, at least one resin and at least one pigment is described, said process comprising the following steps:•extrusion of a mixture containing said at least one resin and said at least one pigment without induced heating;•subsequent extrusion, with induced heating, of the mixture obtained from the preceding extrusion;•granulation of the mixture thus obtained. With the abovementioned process it is possible to obtain a composition having granules with an average diameter less than 2 microns and a greater homogeneity than the known processes. |
