Abstract: Optical products that comprise a composite coating having multiple bilayers of a first layer and a second layer, each provided with a binding group component which together form a complementary binding group pair, the multiple bilayers comprising: at least one bilayer a) comprised of a first pigment or pigment blend that exhibits a color reflection value that is less than about 2.5; at least one bilayer b) comprised of a pigment or pigment blend that selectively blocks visible light in a wavelength range of interest; and at least one bilayer c) comprised of a second pigment or pigment blend that exhibits a color reflection value that is less than about 2.5, wherein the optical product selectively blocks visible light in the wavelength range of interest, while exhibiting a color reflection value that is less than about 2.5.
