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.
