A protective coating consisting of an aluminum or magnesium phosphate complex is used to encapsulate a wide variety of organic and inorganic particles. The coating is particularly applicable to organic and inorganic pigments and serves to improve the light, heat and chemical stability of these pigments. The coating is formed in situ by complexing the phosphate with the metal, preferably in the presence of ions of fluoride or fluoborate and depositing the same onto the surface of the particles. |
