Document Type and Number:
Japanese Patent JP2012178204
Kind Code:
A
Abstract:
To provide a patterning formation method with which each area of a thin film made of specific photochromic compounds can be easily formed through patterning in a storage area of multiple recording.
Each area of a thin film is formed in a storage area having any of at least three or more types of absorption spectra by applying one or more treatments among an irradiation treatment of ultraviolet light of a controlled amount of light, a heating treatment of different temperatures and an irradiation treatment of a laser beam of a controlled amount of light to the thin film of specific diaryl ethane compounds for each predetermined area.
