Document Type and Number:
WIPO Patent Application WO/1999/049338
Kind Code:
A1
Abstract:
An optical material made of a resin containing a large amount of ions of a rare earth metal regardless of the kind of the metal; and a process for producing the material. The optical material is characterized by comprising an acrylic resin containing: phosphate groups derived from a monomer containing a phosphate group; optionally substituted amino groups; and a metal ion ingredient comprising rare earth metal ions. The process is characterized by comprising the step of polymerizing a monomer composition comprising a monomer containing a phosphate group and at least either of an aminated monomer and an amino compound.
