Article having a 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 M1Xm, a hydrolyzate thereof or a hydrolysis/polycondensation product thereof, and a metal compound represented by R1M2Yn, a hydrolyzate thereof or a hydrolysis/polycondensation product thereof, wherein at least one of M1 and M2 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 M1 and M2.
