摘要

The present invention relates to novel monodisperse particles, which comprise at least one broad spectrum absorber contrast agent and/or at least one precursor of a broad spectrum absorber contrast agent, which is encapsulated in the monodisperse particle, novel colourant compositions, to uses thereof in colouring a substrate and to substrates that are coloured (at least in part) using the colourant compositions.
