Procedure:

(3) The constituents of the phase A were weighed out in the main beaker and stirring was carried out with a Moritz stirrer while maintaining at ambient temperature. The stirring rate was adjusted as a function of the amount manufactured and of the viscosity of the mixture. Stirring was maintained until a homogeneous mixture was obtained. The phase B was added with stirring. Stirring was maintained until a homogeneous mixture (absence of clumps) was obtained. The phase C was prepared separately by dispersing the Silica Silylate in the mixture of the two oils in a beaker using a spatula. The mixture C was added while stirring with the Moritz stirrer. Stirring was maintained until a homogeneous mixture was obtained. The phases D and E were added with stirring. Stirring was maintained for 10 minutes. The stirring rate was adjusted as a function of the amount manufactured and of the viscosity of the mixture. Finally, the phase F was added while stirring with the Moritz stirrer. Stirring was maintained until a homogeneous mixture and a good pigmentary dispersion (absence of clumps) were obtained. Packaging was subsequently carried out rapidly.

(4) It was observed that Example 1 according to the invention, comprising the lipophilic film-forming polymer of the silsesquioxane resin type, makes it possible, after centrifuging at 1000 rpm for one hour, at ambient temperature and standing for

(5) 24 hours, at ambient temperature, in a 30 ml flask, to give a “clean” sedimentation of the pigments which is reflected by a transparent salting out and by a ready and homogeneous redispersion of the cake, in contrast to Example 2 devoid of lipophilic film-forming polymer.
