METHOD FOR THE PRODUCTION OF METAL OXIDE PIGMENT COMPOSITE OF CONTROLLED AGGLOMERATING PROPERTIES AND RESPECTIVE PRODUCT

摘要

It is disclosed a process for the preparation of a composite containing submicron sized particles of metal oxide pigment and a natural-based organic compound, comprising a step of grinding a metal oxide pigment and a oligomeric and/or polymeric carbohydrate together by means of a ball mill, so as to obtain a pigment composite containing particles having a submicron granulometry and an outer surface partially or completely covered by said oligomeric and/or polymeric carbohydrate; it is also disclosed a so-obtained pigment composite comprising pigment particles having a mean hydrodynamic diameter smaller than 1 µm.
