Resumen

The invention relates to a hybrid pigment consisting of an organic dye which functionalises and directs the structure of a nanocrystalline calcium phosphate ceramic. The organic dye is obtained by condensation of a substituted nitrobenzaldehyde and is covalently and/or electrostatically bonded to the nanocrystalline calcium phosphate matrix, also forming microspheres that are located in the calcium phosphate matrix. Both the hybrid pigment and the organic dye are metal-free and water-resistant and can be used in many applications, such as for cement dyes, textile dyes and dyes for other commodities.
