摘要

"METHOD FOR DYING AN OPTICAL SUBSTRATE, COATING COMPOSITIONS THAT IS SUITABLE FOR FORMING AN ABRASION-DYINGABLE COATING LAYER, AND FOR DYING AN OPTICAL SUBSTRATE, AND," OPTICAL SUBSTRATE. " The present invention provides a method for dyeing an optical substrate. The method includes the steps of applying a coating composition containing: sym a polymerizable monomer having a polyoxyalkylene backbone containing at least four contiguous oxyalkylene units, and sym an abrasion resistant agent and / or a polymerizable monomer with high crosslinking to the optical substrate, polymerizing the coating composition to form an abrasion resistant coating layer, and introducing a dyeing compound into the coating layer to thereby dye the optical substrate. The invention also provides a coating composition and an optical substrate which is dyed according to the method of the invention.
