Photonic crystal film and method of manufacturing the same and anti-counterfeiting product using the same

摘要

The present invention relates to a photonic crystal film, a manufacturing method thereof, and an anti-falsification product having the same. More specifically, the manufacturing method comprises the following steps of: a) applying a dispersion solution including a polyfunctional compound containing at least two photopolymeric functional groups, a colloid particle, and a photoinitiator and covering a first base material coated with the dispersion solution with a second base material; b) ripening the applied dispersion solution at a temperature of 50°C or more to less than 200°C; and c) polymerizing the ripened dispersion solution by irradiating light to the dispersion solution. Moreover, at least one selected from the first base material and the second base material is a transparent base material.
