Abstract:
A method of printing an image that diffracts radiation is disclosed. The method includes assembling an ordered periodic array of particles on a substrate, wherein the array of particles diffracts radiation in a wavelength band dependent on viewing angle; printing an imaging composition onto a portion of the array in a configuration of an image; shifting the wavelength band of radiation diffracted and changing the refractive index by the printed portion of the array so that the printed portion diffracts radiation at a different wavelength band and reflectivity intensity from a remaining portion of the array; and fixing the printed portion of the array, such that the printed portion of the array diffracts radiation and exhibits the image.
