PRINTED PRODUCT HAVING ARBITRARY IMAGE AND MADE OF CHOLESTERIC LIQUID CRYSTAL FILM

摘要

PROBLEM TO BE SOLVED: To provide a printed product having a large optical interference color density by more simply and effectively printing the product having an arbitrary image made of a cholesteric liquid crystal film. SOLUTION: In the printed product having an arbitrary image and made of a cholesteric liquid crystal film, the film is formed of a laminate of a left- handed optical rotatory power reflecting layer for reflecting a left-handed optical rotatory power and made of a polymer liquid crystal exhibiting a cholesteric phase and a right-handed optical rotatory power reflecting layer for reflecting a right-handed optical rotatory power and made of a polymer liquid crystal exhibiting a chlolesteric phase and has an arbitrary image made of the cholesteric liquid crystal film having a difference between a maximum wavelength of the reflected wavelength spectrum of the left-handed optical rotary power reflecting layer and a maximum wavelength of the reflected wavelength spectrum of the right-handed optical rotatory power reflecting layer of a range of 0 to 50 nm.
