Abstract
Water-resisting organic optical material having excellent transmittancy in visible range and less than 40% transmittancy in infra red range can be easily prepared by adding a metal compound for supplying a desired amount of Cu++ ion, together with a compound for supplying carboxyl radical, phosphoric radical and/or sulfonic radical to a matrix resin.
Claims4
Organic optical material having excellent transmittancy in visible range, less than 40% in infra red range from 700 nm to 800 nm and improved water resistivity which comprises 0.05-40% by weight (calculated as the radical content) of a compound for supplying at least one radical selected from the group consisting of carboxyl radical, phosphoric radical and sulfonic radical, 0.05-40% by weight (calculated as ion content) of metal compound for supplying metal ions containing 80% or more of Cu.sup.++ ion therein and the balance of high molecular organic matrix resin.
Process for the preparation of an organic optical material which comprises adding a metal compound for supplying a desired amount of Cu.sup.++ ion, together with a compound for supplying carboxyl radical, phosphoric radical and sulfonic radical, to organic matrix resin.
