Appeal No. 1999-1071
Application 08/453,770
The subject matter on appeal is represented by process claim
94, and product claims 176 and 207, set forth below:
94. A process for making a plastic eyeglass lens using a
composition comprising a photoinitiator, an aromatic containing
bis(allyl carbonate)-functional monomer, and at least one
polyethylenic-functional monomer containing at least two
ethylenically unsaturated groups selected form acrylyl and
methacrylyl, the process comprising:
placing a lens forming composition into a mold cavity
formed at least in part by a first mold member with a casting
face and a noncasting face, and a second mold member with a
casting face and noncasting face, the composition comprising a
photoinitator, an aromatic containing bis(allyl carbonate)-
functional monomer, and at least one polyethylenic-functional
monomer containing at least two ethylenically unsaturated groups
selected form acrylyl and methacrylyl, and wherein the
composition is curable by exposure to ultraviolet light to form a
substantially clear eyeglass lens in a time period of less than
one hour;
curing the lens forming composition to form a
substantially clear eyeglass lens by exposing the composition to
ultraviolet light for a time period of less than one hour; and
cooling at least a portion of the mold cavity, the
cooling being conducted while the lens forming composition is
curing.
176. An eyeglass lens prepared using the process of
claim 94.
