Abstract: Optical products are disclosed that include a polymer substrate; a composite coating, deposited on the polymer substrate; a permeating adhesive, which permeates the composite coating and is in contact with the polymer substrate; and a protective layer, secured to the composite coating by the permeating adhesive. The composite coating includes at least a first layer and a second layer, each of which is provided with a binding group component which together form a complementary binding group pair. The optical products exhibit improved resistance to delamination during storage and use.

Abstract: Optical products that include a composite coating, deposited on a substrate, provided with at least one bilayer having a first layer and a second layer, each provided with a binding group component which together form a complementary binding group pair. The at least one bilayer comprises a pigment blend that includes: a) at least two pigments that, when mixed together and formed into a bilayer, exhibit a color reflection value that is less than about 2.5; and b) one or more pigments that when mixed and formed into a bilayer selectively block visible light in a wavelength range of interest.

Abstract: Special effect films are disclosed that comprise a polymeric substrate and a composite coating. The composite coating is provided with a first layer comprising a polyionic binder and a second layer comprising interference particles having at least one highly refractive layer and at least one lower refractive layer, and a difference in refractive index between the highly refractive layer and the at least one lower refractive layer is at least 0.1 units.

Abstract: Optical products and methods of making them are disclosed, the optical products comprising a polymeric substrate and a composite coating. The composite coating, in turn, comprises: a first layer comprising a polyionic binder, and a second layer comprising insoluble particles that absorb electromagnetic energy and insoluble particles that absorb relatively little visible light. Each of the first layer and the second layer includes a binding group component which together form a complimentary binding group pair.
