Patent ID: 6849209

Claim:
A method for producing an article having a predetermined surface pattern, which comprises the steps of disposing closely a sol-gel material between a patterning die and a substrate in the form of a film and heating them to coat the surface of the substrate with a gel film having a surface pattern which is the inverse of the surface pattern of the patterning die, wherein the sol-gel material comprises: (A) at least one compound selected from the group consisting of the silane compound represented by the following formula (1), the hydrolysate of the silane compound, and the polycondensate of the hydrolysate: R 1 SiX 3 (1) wherein R 1 is an alkyl group or a hydrogen atom, and X is an alkoxyl group or a halogen atom, and (B) at least one compound selected from the group consisting of the silane compound represented by the following formula (2), the hydrolysate of the silane compound, and the polycondensate of the hydrolysate: R 2 SiY 3 (2) wherein R 2 is an aryl group or a substituted aryl group, and Y is an alkoxyl group or a halogen atom, wherein the sol-gel material comprises 5 to 50 mol % of the component (A) and 50 to 95 mol % of the component (B) based on the total of the components (A) and (B).
