ENCAPSULATED NANOSCALE PARTICLES OF ORGANIC PIGMENTS

摘要

Colorant loaded nanocapsules include a polymeric capsule shell, and a colorant loaded inside the polymeric capsule shell Such colorant loaded nanocapsules can be made by providing colorant particles and a block copolymer having a minor number of colorant-affinic monomer units and a major number of non-colorant-affinic monomer units, associating the colorant particles with at least some of the colorant-affinic monomer units of the block copolymer, subjecting the block copolymer to a micellization treatment to form a polymeric capsule around the colorant particles, optionally crosslinking the polymeric capsule, and optionally reinforcing the polymeric capsule
