Abstract

The invention relates to a coating material with the refractive index approximate to that of a mirror. The coating material comprises methacrylic acyloxy propyl trialkyl silane, sulfydryl propyl trialkyl silane, zirconium oxide wrapped by antimony oxide and integrally combined with titanium oxide, compound metal particles manufactured from silicon oxide and magnesium oxide, dicyandiamide, organic carboxylic acid and a cobalt (II) compound. The refractive index of the coating material is approximate to that of a base body, and the coating material has the anti-aging property.

Description

technical field [0001] The invention belongs to the field of surface materials, and specifically refers to a coating material for lenses, whose refractive index is similar to that of lens materials. Background technique [0002] One of the problems with forming coatings on ophthalmic lenses made of high-refractive-index materials that have become thinner due to the use of high-refractive-index materials for plastic lenses for vision correction or sunglasses is the relationship between the coating and the ophthalmic lens. The interference pattern caused by the difference in refractive index between them. This interference pattern causes appearance defects of the ophthalmic lens. [0003] By making the refractive index of the hard coat layer close to that of an eyeglass lens using a high-refractive-index material, we have developed a technology that can realize a high-refractive-index hard coat layer. The refractive index of the formed hard coat layer is increased by adding ...
