#CMT# #/CMT# Coated product contains a substrate and a coating having a real part of the complex refractive index of at least 1.70, an imaginary part of the complex refractive index of not more than 0.016, a surface roughness of less than 20 nm and a scratch resistance of not more than 0.75 mu m. The real and imaginary parts of the refractive index are measured at a wavelength of 400-410 nm. The surface roughness is measured as a Ra value using atomic force spectroscopy. The scratch resistance is determined on the surface of a polycarbonate substrate using a diamond needle having a tip radius of 50 mu m at an advancing speed of 1.5 cm/s. #CMT# : #/CMT# Independent claims are also included for the following: (1) Optical data memory containing the above coated product; and (2) Casting solution used in the production of the coated product. #CMT#USE : #/CMT# Coated product used in the production of a data memory (claimed). #CMT#ADVANTAGE : #/CMT# The coated product has high scratch resistance. #CMT#ELECTRONICS : #/CMT# Preferred Features: The coated product is obtained by exchanging water in an aqueous nano-particle suspension using an organic solvent, adding a binder to form a casting solution, applying to a substrate or information and memory layer and crosslinking by thermal or photo-chemical methods. #CMT#POLYMERS : #/CMT# Preferred Materials: The substrate is made from glass, quartz, silicon, polycarbonate, polymethacrylate, polyester, cycloolefin polymer, epoxy resin or resin hardened by ultraviolet light. |
