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.sub.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.
