SURFACE TREATMENT AGENT FOR OPTICAL MATERIAL, AND OPTICAL MATERIAL

摘要

A surface treatment agent for an optical material comprising an organic silicon compound having a functional group selected from a highly polar functional group, a hydroxyl group-containing group, a silicon atom-containing hydrolyzabie group, or metal salt derivatives thereof bonded to silicon atoms directly or via a functional group with a valency of (n+1 ) (n is a number equal to 1 or greater); and having at least one structure in the molecule in which the silicon atoms are bonded to any siloxane unit represented by R1 3SiO1/2, R1 2SiO2/2, R1SiO3/2, and SiO4/2.
