An article having a predetermined surface shape is coated on a substrate surface with a gelled film having a high refractive index, excellent heat resistance, high film hardness and excellent transferability.n n n A sol-gel material is placed between a substrate and a mold and placed in a film form, and then heated to form an article in which a gelled film having a transfer surface is coated on the substrate surface. The sol-gel material contains a metal compound represented by M 1 X m , a hydrolyzate thereof or a hydrolyzed condensation product thereof, and a metal compound represented by R 1 M 2 Y n , a hydrolyzate thereof or a hydrolyzed condensation polymer thereof. , At least one of M 1 and M 2 is a metal atom of Ti, Zr, Al, Ge, Sn or Sb, and the metal atom accounts for at least 10 atomic% of M 1 and M 2 . |
