MATERIAL FOR FORMING PATTERN, FILM-LIKE PATTERN, AND PATTERN FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a new pattern forming material for easily forming a fine pattern which has a smooth surface and in which a fine pattern wherein phases different by turbidity are alternately arranged in an arbitrary shape in a film surface direction, and to provide an optical pattern using the same and a forming method for the same. SOLUTION: A base material is coated with the pattern forming material of which the turbidity is thermally reversible before fixation by radiation of an electromagnetic wave but becomes thermally irreversible after fixation by radiation of the electromagnetic wave. The electromagnetic wave is radiated in accordance with a desired pattern to fix the turbidity of an irradiated part. Then a temperature condition is changed to change the turbidity of a non-irradiated part while keeping the turbidity of the irradiated part, and the electromagnetic wave is radiated over the entire surface in this state to fix the turbidity of the part which is not irradiated in a first irradiation stage.
