Pigmented polymerizable compositions and optical articles prepared therefrom

摘要

Provided is a polymerizable composition including: (a) a polymerizable component; and (b) a pigment component the pigment component includes: (i) an ionic or amphoteric dispersant material; and (ii) pigment nanoparticles uniformly dispersed in the dispersant material (i). The nanoparticles have a particle size of up to 500 nanometers. Also provided is a polymerizable composition of: (a) a polymerizable component including: (i) diethylene glycol bis(allyl carbonate); and (ii) a radical initiator; and (b) a pigment component which includes: (i) an ionic or amphoteric dispersant material derived from polycaprolactone; and (ii) pigment nanoparticles of ultramarine blue having an average particle size of up to 500 nanometers, uniformly dispersed in the dispersant material.
