CHOLESTERIC COLOR FILTER AND METHOD OF MANUFACTURING SUCH
摘要
<p>The invention pertains to a method of manufacturing a layer of a cholesterically ordered polymer material, in which the material is oriented in such a way that the axis of the molecular helix of the cholesterically ordered material extends transversely to the layer, wherein the method comprises the following steps: a) providing a layer comprising a cholesterically ordered material, which material comprises a quantity of a convertible compound, the conversion of said compound being inducible by radiation; b) irradiating the layer to convert at least a part of the convertible compound in the irradiated parts of the layer; c) optionally at least partially polymerizing and/or cross-linking the cholesterically ordered material to form a three-dimensional polymer; d) applying a diffusion agent onto the layer to transversely swell the layer as a function of the concentration variation of the diffusion agent; e) fixing the diffusion agent to the polymer to freeze in the formed structure.</p>
