Process for producing antireflection-treated surfaces

A process for producing an article having at least one surface which exhibits antireflection properties, comprising the step of:

• a) transferring to at least one surface of an article a surface structure of a polymeric film, wherein said polymeric film comprises a thermoplastic material,
• said surface structure comprising individual, randomly distributed elevations, wherein said elevations rise 0.01 to 15 microns above the lowest regions of the surface having the elevations,
• so that the resultant article comprises a mirror image of said surface structure, wherein said surface structure has a substantially uniform configuration comprising mutually linked individual structures, wherein said surface structure comprises continually repeating elementary cells which have a mean diameter of about 10 to 800 microns,
• said transferring comprising transferring the surface structure of said film to said article by applying a surface of said film having said structure to said article, so as to form a mirror-image of said structure on said article and, thereafter, optionally removing said film,
• wherein said film comprises a uniaxially or biaxially oriented film which has been heat-set.

A process for producing an article having at least one surface which exhibits antireflection properties, comprising the step of:

• a) transferring to at least one surface of an article, a surface structure of a polymeric film, wherein said polymeric film comprises a thermoplastic material,
• said surface structure comprising individual, randomly distributed elevations, wherein said elevations rise 0.01 to 15 microns above the lowest regions of the surface having the elevations,
• so that the resultant article comprises said surface structure, wherein said surface structure has a substantially uniform configuration comprising mutually linked individual structures, wherein said surface structure comprises continually repeating elementary cells which have a mean diameter of about 10 to 800 microns,
• said transferring comprising applying said film to said article as a cover layer wherein a surface of the film comprising said structure faces outward from said article,
• wherein the elevations are formed by the presence of at least one of inorganic or organic additives in the film.
