    摘要： A process for producing an article having a fine uneven surface, coated with a film which has high heat resistance, does not crack and does not peel off from a substrate. The process for producing the article comprises disposing a film-forming solution between a substrate and a mold in the form of a film so as to make the solution closely contact with the substrate and the mold, said solution being prepared by carrying out the hydrolysis and dehydration polycondensation reaction of a stock solution containing a specific silane compound (A) having an unhydrolyzable organic group and a hydrolyzable group, a specific silane compound (B) having a hydrolyzable group and a catalyst, and heating to form an article having an uneven film having a surface shape which is the inversion of the surface shape of the mold on the surface of the substrate. The film-forming solution contains the above silane compounds (A) and (B) in the form of unhydrolysates in amounts of 0.5 to 40 wt % and 0.5 to 60 wt % based on the amount of the above silane compound (A) and the amount of the above silane compound (B) contained in the stock solution, respectively. A condensate formed by the dehydration condensation reaction of the film-forming solution has a molecular weight of 300 to 1,900.

The adhesive layer is formed from a matrix containing silicon, titanium, zirconium, aluminum or germianium, and oxygen atoms. At least part of the atoms is bonded to other atom(s) through a polyvalent hydrocarbon group and directly bonded a monovalent hydrocarbon group. The refractive index value of the adhesive layer approximates to the refractive index values of the at least two optically transparent optical parts. An adhesive composition for bonding optical parts and a method of bonding optical parts are also proposed.
