COLOR-LOADED POLYMER MICROPARTICLES |
摘要 |
Water-soluble dyes are loaded on polymer microparticles having a particle size of 0.01 to 50 microns. The carrier polymer microparticles are produced by emulsion polymerizing a mixture of at least one monofunctional monomer with a crosslinking monomer in the presence of a polymerizable amino acid derivative or a hydrophilic oligomer having a plurality of amphoionic groups. Water-soluble dyes are added to the resulting emulsion. Color-loaded polymer microparticles are obtained by removing water from the emulsion followed by resuspending in an organic solvent.
