Реферат: There is provided new mono-(meth)acrylate functionalized silicone monomers containing carbosiloxane linkage for improved hydrolysis resistance, useful in making water absorbing silicone-hydrogel films for contact lens applications. This invention also provides homo-polymers and copolymers made from the mono-(meth)acrylate functionalized hydrophilic silicone monomers described herein. Also provided is a process for producing the monomers and polymers described herein and contact lenses produced from the same.
Film having low refractive index film and method for producing the same, anti-reflection film and method for producing the same, coating liquid set for low refractive index film, substrate having microparticle-laminated thin film and method for producing the same, and optical member
