摘要

Red pigments based on gold nanoparticlesfor decorative applications, procedure for its preparation andits use.;The present invention relates to a pigmentred based on gold nanoparticles for decorative applications,which is essentially comprised of gold nanoparticles,dispersed in a matrix of a selected protective materialbetween oxides, oxyhydroxides and combinations thereof, atprocedure for preparing said pigments and their use forelaboration of red-purple decorations inglass, glazing and ceramic materials, especially in thosematerials to be subjected to higher cooking temperaturesof 500 ° C.
