Coating compositions capable of producing hardened articles with high refractive index and coatings obtained from the compositions

摘要

Particulates of at least one oxide selected from the group consisting of iron oxides, titanium oxides, cerium oxides, zirconium oxides, antimony oxides, zinc oxides and tin oxides or composite oxides thereof, epoxy group-containing silicon compounds or partial hydrolyzates thereof, molecules At least one unsaturated unit having at least one binding unit selected from the group consisting of -O-, -CO-O-, -S-, -CO-S- and -CS-S-, having an OH group or a SH group in the backbone thereof; A coating composition comprising a group and comprising an organic compound dissolved in water or a lower alcohol having up to 4 carbon atoms and capable of producing a cured article having a high refractive index. When cured on a high refractive index substrate, the composition produces a cured article having a very high strength and capable of deep salting while suppressing the formation of interference fringes. Also provided are coated articles comprising coated plastic lenses having a cured film of the composition.
