Abstract:
A process for producing an article having a predetermined surface configuration, comprising the steps of: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, said substrate being an inorganic substrate having a surface coated with a surface treating composition which comprises a silicon compound represented by the following formula (3), as a silane coupling agent: R4R5kSi(R6)3-kâ€ƒâ€ƒ(3) wherein R4 is an organic group having a methacryl group, acryl group, epoxy group, allyl group, mercapto group, amino group, or a vinyl group, R5 is an alkyl group, R6 is a group or atom having hydrolyzability, and k is 0 or 1, or a hydrolyzate thereof, and a compound represented by the following formula (4):M(R7)pâ€ƒâ€ƒ(4) wherein M is silicon, titanium, zirconium or aluminum, R7 is a group or atom having hydrolyzability, and p is 4 when M is silicon, titanium or zirconium and 3 when M is aluminum, or a hydrolyzate thereof;applying at least one of heat and ultraviolet radiation to the composition in the form of a film; removing the mold and, as required, heating the film; and forming the article in which the surface of the substrate is covered with a film having a surface configuration which is the inversion of the surface configuration of the mold.
