  The present invention relates to a method of producing coloured carrier particles (substrates), which comprises a) dispersing the carrier particles in a solution of a colorant or latent pigment, adding the carrier particles to a solution of a colorant or latent pigment, or adding a latent pigment or a colorant to a dispersion of the carrier particles, b) precipitating the colorant or latent pigment onto the carrier particles, and c) in the case of a latent pigment, subsequently converting it to the pigment, and to the coloured substrates obtainable by such a method, and also to the use thereof. Using the methods according to the invention it is possible to obtain colorations and coloured substrates that have surprisingly good light-fastness properties.
