Abstract: An article having a predetermined surface configuration, such as an optical element having fine irregularities in the surface which has high heat resistance, small heat shrinkage at the time of molding a film and high dimensional stability, and a production process therefor. The article having a predetermined surface configuration is produced by setting a composition comprising a compound which contains a dimethylsiloxane skeleton having at least three recurring units and at least one polymerizable organic group in the molecule between and in contact with the surface of a substrate and the molding surface of a mold in the form of a film, applying at least one of heat and ultraviolet radiation to the composition, removing the mold, and heating as required to form a film having a surface configuration which is the inversion of the surface configuration of the mold on the surface of the substrate.

Abstract: There can be provided a method for producing a pattern film-coated article which has excellent film formability, can remove unexposed portions of a film completely in the development step after exposing the film to light. and has excellent pattern accuracy; and a photosensitive composition. The method for producing a pattern film-coated article comprises the steps of coating a photosensitive composition comprising an organometallic or organosilicon compound having photosensitivity and a hydrolyzable metal or silicon alkoxide on a substrate, irradiating the coated film on the substrate with light to polymerize the exposed portions of the coated film and then dissolving unexposed portions to remove them, wherein a pattern film-coated article is produced from an allyl group-containing metal or silicon alkoxide as the organometallic or organosilicon compound.
