摘要:
A chemiluminescent device is disclosed wherein a first polymeric sheet having a shaped cavity therein is sealed around its periphery to a second polymeric sheet and the cavity contains (1) an absorbent article produced from a polyolefin, or a polyester or glass fibers and being of substantially the same shape as the cavity and (2) a sealed receptacle containing a first liquid component of a chemiluminescent light composition and wherein there is also present, outside said sealed receptacle, a second liquid component of a chemiluminescent light composition, said absorbent article conforming to seven critical chemical limitations.
摘要:
The invention provides compositions for forming ocular devices which compositions contain latent UV absorbers. The compositions of the invention may be used to conveniently and efficiently produce ocular devices through UV initiated, free radical polymerization.
