Article having predetermined surface shape and method for production thereof
摘要:
An article with a predetermined surface pattern that is coated with a film which makes possible the complete transfer of the pattern of a patterning die and thick-film patterning having a depth to the order of several tens of micrometers, prevents the occurrence of cracks, has high film hardness, and has a surface pattern which is the inverse of the surface pattern of the patterning die. This article is produced by joining a patterning die closely to a substrate with a sol-gel material containing the silane compound represented by the formula: R1SiX3 (wherein R1 is an alkyl group or hydrogen and X is an alkoxyl group or a halogen atom) and the silane compound represented by the formula: R2SiY3 (wherein R2 is an aryl group or a substituted aryl group and Y is an alkoxyl group or a halogen atom) disposed therebetween 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.
