Antisoiling hardcoat
First Claim
1. A method for making an antisoiling hardcoat comprising coating and curing on a substrate a ceramer coating comprising inorganic oxide particles dispersed in a free-radically polymerizable binder matrix, and coating and curing atop the ceramer coating an antisoiling layer comprising a free-radically polymerizable fluorochemical.

Abstract
An antisoiling hardcoated film comprising a substantially transparent substrate, a hardcoat layer comprising inorganic oxide particles dispersed in a binder matrix, and an antisoiling layer comprising a perfluoropolyether. The antisoiling layer can be very thin, thus reducing the cost of the perfluoropolyether. The film has very good scratch, smudge and glare resistance and very good interlayer adhesion and durability. The film can be in the form of a single flexible substrate or a stack of such substrates. The film or stack can be sized to fit the display screen of an electronic display device such as a personal digital assistant or cell phone.

2. A method for making a display element comprising applying to a substantially transparent substrate a curable hardcoat layer comprising inorganic oxide particles dispersed in a free-radically polymerizable binder matrix, curing the hardcoat layer, applying to the hardcoat layer a curable antisoiling layer comprising a perfluoropolyether, and curing the antisoiling layer.
