Abstract
A transparent shaped article having an enhanced anti-reflective effect is produced by treating with an activated gas the surface of a transparent shaped article having a surface layer containing a finely divided particulate inorganic substance having an average particle size of from about 1 to about 300 milli-microns. If desired, the transparent shaped article treated with the activated gas is coated with a protective coating material.
Claims19
A process for producing a transparent shaped article having an enhanced anti-reflective effect, said article either being an organic material or having a coating of organic material thereon which comprises treating with an activated gas the surface of a transparent shaped article, said surface layer comprising a finely divided particulate inorganic substance having an average particle size of from about 1 to about 300 milli-microns dispersed in said organic material.
A process for producing a transparent shaped article having an enhanced anti-reflective effect, said article being either organic material or having a coating of organic material thereon, which comprises treating with an activated gas the surface of a transparent shaped article having a surface layer comprising a finely divided particulate inorganic substance having an average particle size of from about 1 to about 300 millimicrons dispersed in said organic material, whereby the organic portion of the surface layer is partially etched thereby forming the anti-reflective layer.
A process for producing a transparent shaped article having an enhanced anti-reflective effect, which comprises treating with an activated gas the surface layer of a transparent shaped article having a surface layer containing a finely divided particulate inorganic substance having an average particle size of from about 1 to about 300 millimicrons whereby said activated gas partially etches the surface layer of the transparent shaped article and leaves said finely divided particulate inorganic substance substantially unchanged in form and state to form the anti-reflective layer.
