摘要： 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.
摘要翻译：公开了一种打印衍射辐射的图像的方法。该方法包括将有序的周期性粒子阵列组装在衬底上，其中颗粒阵列衍射取决于视角的波长带中的辐射; 在图像的配置中将成像组合物打印到阵列的一部分上; 使辐射的波长带变换并且通过阵列的印刷部分改变折射率，使得印刷部分衍射不同波长带的辐射和阵列的剩余部分的反射强度; 并且固定阵列的打印部分，使得阵列的印刷部分衍射辐射并展现图像。
