STRUCTURAL LIGHT EMITTING UNEVEN FILM, STRUCTURAL COLORATION UNEVEN FILM AND STRUCTURAL COLORATION COATING FILM

摘要

PPROBLEM TO BE SOLVED: To provide a structural coloration uneven film which has no difference between the front and rear faces thereof and can provide a brilliant material mixed in a coating film and achieving stable structural coloration, to provide a brilliant material obtained by cracking the structural coloration uneven film, and to provide a structural coloration coating film containing such a brilliant material. PSOLUTION: The brilliant material is obtained by cracking the structural coloration uneven film so that an average longest diameter of cracked pieces is made 1-100 m. The structural coloration uneven film comprises a material having a refractive index n and has an uneven shape inflected periodically at a pitch P, wherein the product nP of the refractive index n and the pitch P is 380-780 nm.
