  The present invention relates to a method of producing coloured carrier particles which comprises which comprises: a) dispersing a pigment in aqueous solution, b) adding soda waterglass, c) precipitating SiO 2 and the pigment onto the carrier particles by lowering the pH value. Using the methods according to the invention it is possible to obtain colorations and coloured substrates that have surprisingly good light-fastness properties.
