Abstract
A method for forming a reflective element substrate for a mirror assembly of a vehicle includes generally continuously forming an elongated sheet of substrate material and applying a substantially transparent functional film to a surface of the elongated sheet. The substantially transparent functional film is unrolled from a reel or roll of the film and the unrolled film is applied to the surface of the elongated sheet generally continuously as the sheet is formed or extruded or cast. Two or more mirror substrates are formed from the elongated sheet after the film is applied to the surface of the sheet.

A method for forming a reflective element substrate for a mirror assembly of a vehicle comprising:
- generally continuously forming an elongated sheet of substrate material, said substrate material comprising a polymeric resin material;
- applying a substantially transparent functional film to a surface of said elongated sheet, wherein said functional film comprises an ultrathin glass material which is sufficiently flexible to be provided in a reel or roll;
- unrolling said substantially transparent functional film from a reel or roll of said film and applying said unrolled film to said surface of said elongated sheet generally continuously as said sheet is formed or extruded or cast;
- and
- forming two or more mirror substrates from said elongated sheet after said film is applied to said surface of said sheet.
