Abstract:
An identification film and pattern having high transparency and a reflectance spectrum with respect to a particular wavelength and including photonic crystals patterned into a particular shape and an anticounterfeiting product including the same are disclosed.A highly transparent colloidal photonic crystal film is easily manufactured using photocurable colloidal suspensions.Even though a plurality of patterns (including sub-patterns) is formed in plural films, there is no reduction in optical characteristics such as transparency, reflectance spectra, and the like. Thus, a film patterned into a desired shape is manufactured and thus usability thereof is enhanced, and a plurality of reflectance spectra with various wavelength ranges is provided and thus identification capability or security is enhanced.
