ARTICLE HAVING PREDETERMINED SURFACE SHAPE AND METHOD FOR PREPARATION THEREOF

摘要

An article having a predetermined surface configuration comprising a substrate and a gelled film having a high refractive index, excellent heat resistance, high film hardness and excellent transferability formed on the surface of the substrate. A process for producing an article having a gelled film with a transferred surface on the surface of a substrate by arranging a sol-gel material with close contact between the substrate and a mold in the form of a film and heating it. The sol-gel material contains a metal compound represented by M<1>Xm, a hydrolyzate thereof or a hydrolysis/polycondensation product thereof, and a metal compound represented by R<1>M<2>Yn, a hydrolyzate thereof or a hydrolysis/polycondensation product thereof, wherein at least one of M<1> and M<2> is a metal atom selected from Ti, Zr, Al, Ge, Sn or Sb and the metal atom accounts for at least 10 atom% of the total of M<1> and M<2>.
