ABSTRACT:
A film that exhibits increased scratch resistant characteristics. The film is formed from a layer of crosslinkable oligomeric resin composition on a base. The film is made by: forming the layer of crosslinkable oligomeric resin composition on the base, and curing the resin composition to an extent that the film exhibits a haze decrease of less than or equal to 60 percent after abrading according to the ASTM D-968-81 procedure using 200 milliliters of sand. Preferably, the layer has a microstructure of alternating tips and grooves. Such films are useful in backlit displays which are useful in computers and the like.
