[0269] Procedure

[0270] The constituents of phase A1 are weighed in the main beaker and stirred, at an ambient temperature using a Moritz mixer (600 to 700 rpm) for 15 minutes until homogenization.

[0271] Phase A2 is prepared separately by grinding three times, in a three-roll mill, the mixture of pigments and cyclohexasiloxane.

[0272] This phase A2 is then added into the main beaker while stirring using a Moritz mixer (700 to 800 rpm) for 30 minutes at ambient temperature.
