Abstract
A film including: an organic polymeric substrate having a first major surface and a second major surface; an optional acrylic hardcoat layer disposed on the first major surface of the substrate; a siliceous primer layer disposed on the organic polymeric substrate or on the optional acrylic hardcoat layer, wherein the siliceous primer layer includes composite particles including an organic polymer portion and a siliceous portion; and a superhydrophilic surface layer disposed on the siliceous primer layer, wherein the superhydrophilic surface layer includes hydrophilic-functional groups.

A film comprising:
- an organic polymeric substrate having a first major surface and a second major surface;
- an optional acrylic hardcoat layer disposed on the first major surface of the substrate;
- a siliceous primer layer disposed on the organic polymeric substrate or on the optional acrylic hardcoat layer, wherein the siliceous primer layer comprises composite particles that are core-shell particles comprising an organic polymer core particle having a siliceous shell comprising (1) a metal silicate coating or (2) organo-modified silica particles;
- and
- a superhydrophilic surface layer disposed on the siliceous primer layer, wherein the superhydrophilic surface layer comprises hydrophilic-functional groups.
