Optical lenses prepared from crosslinkable acrylic compositions |
摘要 |
An optical lens having an absorbance of less than about 0.1 for visible radiation of a wavelength in the range of from about 400 to about 600 nanometers is prepared from a crosslinkable acrylic composition. The composition consists essentially of an acrylic monomer and an acrylated urethane oligomer and exhibits a shrinkage upon curing of less than about 0.4%. The lens is prepared by introducing the crosslinkable composition into a lens-forming means and curing it until it is substantially crosslinked.
