Abstract
A photocurable composition is provided which includes a vial having bottom and side walls which define a chamber and a photocurable material disposed in the chamber. The side wall circumscribes the bottom wall and includes a colorant so that the side wall will substantially attenuate actinic radiation while minimally attenuating visible light having an approximating spectral wavelength greater than 500 nanometers. By that arrangement, the level of the photocurable material may be visualized through the side wall, while still providing sufficient attenuation of actinic radiation to provide for long term storage of the photocurable material without substantial curing thereof.
