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.

Pigmented polymerizable compositions and optical articles prepared therefrom

A panel carrier system and method for coating panels with the carrier system are disclosed. The carrier comprises a base and protective cover with an enclosure that protects the base when coating compositions are applied to the panels. The carrier system and coated panels may be transported to a curing location, followed by removal and evaluation of the coated panels.

Carrier systems for coating panels

Systems for delivering coating compositions are disclosed. The system may include a support base for supporting a container of a coating composition and a pressure canister movable in relation to the support base from an open position to a closed position in which the pressure canister surrounds the coating composition container and forms a seal with the support base. The system may include a pressure canister that is movable from a delivery position in which the canister is pressurized to a cleaning position in which the canister may be cleaned by a cleaning fixture. The pressure canisters are useful in automated systems for delivering various types of coating formulations.
