The synthesis of polymerizable RhB-based nanocolorants is described. Poly(AAm-co-RhB)
nanocolorants were successfully synthesized for the first time via inverse miniemulsion
polymerization. RhB dye was first functionalized by esterification reaction to introduce an
acrylate polymerizable group. The RhB-acrylate dye was copolymerized with AAm monomer
in an inverse miniemulsion polymerization to produce nanocolorants with superior light and
migration fastness. Crosslinked-poly(AAm-co-RhB) nanocolorants could be obtained based
on the incorporation of a crosslinking agent. Poly(AAm-co-RhB) and crosslinked-poly(AAm
co-RhB) nanocolorants exhibited a morphology of dark solid and core-shell particles,
respectively. In both nanocolorants, the RhB-acrylate dye was completely integrated by
copolymerization into the polymer matrix, and by that, the dye migration was completely

supressed. Both poly(AAm-co-RhB) and crosslinked-poly(AAm-co-RhB) nanocolorants showed high thermal stability as well as high Tg values.
