Title:
COATING COMPOSITION AND OPTICAL ARTICLE
Document Type and Number:
WIPO Patent Application WO/2010/134464
Kind Code:
A1
Abstract:
Disclosed is a coating composition appropriately usable for forming a hard coat film that is obtained by applying the composition onto a light-permeable member, such as a plastic lens having a high refractive index or a photochromic plastic lens having a color-developing function and a high refractive index, and hardening. This coating composition exhibits an extremely improved weather resistance (prevention of discoloration) while sustaining a high refractive index, a good scratch resistance and an excellent adhesiveness to an optical base. Specifically disclosed is a coating composition, comprising: titanium oxide-containing metal oxide microparticles (A) together with titanium oxide-containing metal oxide microparticles (B), provided that the titanium oxide-containing metal oxide microparticles (A) and the titanium oxide-containing metal oxide microparticles (B) have been selected through a specific light irradiation test and show different properties; an epoxy group-containing organosilicon compound (C) such as γ-glycidoxypropyltrimethoxysilane; water (D); an organic solvent (E) such as methyl alcohol; and a hardening catalyst (F) such as aluminum acetylacetonate or magnesium perchlorate, each in a specific amount.
