Field of the Invention The present invention relates to a method for forming a high refractive index layer on an article which requires a high refractive index layer on an optical member represented by a display device, an optical component, or the like. The present invention relates to a high-refractive-index composition having curability when left at room temperature.

る。[0003] These oxide films are formed on a substrate by vacuum evaporation or sputtering. In the method of forming a thin film of an oxide by vacuum deposition, which has been most practically used, the productivity is poor because a large-scale apparatus requiring vacuum is used, and it is difficult to apply the method to a low-cost optical member or the like.

ゲルであるため屈折率は高くない。However, oxide fine particles having a level of transparency that can be used for optical members are generally poor in crystallinity due to the production method, and the refractive index of the particles themselves is not so high. Also, when a material system composed of a metal alkoxide and an organic compound having a polymerizable unsaturated bond is used, the refractive index is not high because the metal alkoxide component is an amorphous gel in the coating film.
