要約
(EN)

[Problems] A coating composition preferably used for forming a hard coating by being applied and cured on a light-transmitting member such as a highly refractive plastic lens or a highly refractive photochromic plastic lens having a function for developing a color, the coating composition markedly improving weather resistance (preventing discoloration) while sustaining high refractive index, scratch resistance and excellent adhesion to the optical material.

[Means for Solution] The coating composition comprises (A) a fine granular metal oxide containing titanium oxide and (B) a fine granular metal oxide containing titanium oxide having dissimilar properties as selected by a specific light irradiation test and, further, contains (C) an epoxy group-containing organosilicon compound such as γ-glycidoxypropyltrimethoxysilane, (D) water, (E) an organic solvent such as methyl alcohol, and (F) a curing catalyst such as aluminum acetyl acetonato or magnesium perchlorate at specific ratios.
