A series of submicron organic pigment microcapsules with high pigment encapsulating efficiency and narrow particles size distribution was prepared via in-situ miniemulsion polymerization. The self-adhesive pigment microcapsules were applied to pigment printing of silk fabrics. It was found from printing qualities that, the K/S value, handle, dry and wet rubbing fastness of silk fabrics printed by pigment microcapsules were much better than those printed by traditional pigment paste. The TEM observation of the printed fabrics further indicated that the presence of adhesive polymeric layer on the pigment particles can remarkably improve the dispersion of pigment particles on fabric surface and the adhesion between pigment particles and the target fabric.
