Title (EN) STRUCTURAL COLOR PRODUCING METHOD
(FR) PROCÉDÉ DE PRODUCTION DE COULEUR STRUCTURALE
(KO) 구조색 생성방법
Abstract: front page image
(EN)Provided is a structural color printing method comprising the steps of: providing a first substrate; forming a composition layer for producing structural color, including magnetic nanoparticles and a curing material on the first substrate; applying a magnetic field to the composition layer for producing structural color to express structural color through a change in the lattice spacing of photonic crystals formed by the magnetic nanoparticles according to an intensity of the magnetic field; and curing the composition layer for producing the structural color to immobilize the lattice spacing of the photonic crystals and to form a structural color printing layer.
(FR)L'invention concerne un procédé d'impression en couleur structurale comprenant les étapes consistant: à prendre un premier substrat; à former une couche de composition pour produire une couleur structurale, comprenant des nanoparticules magnétiques et un matériau de durcissement sur le premier substrat; à appliquer un champ magnétique sur la couche de composition pour produire une couleur structurale afin d'exprimer une couleur structurale à travers une modification du pas de réseau de cristaux photoniques formés par les nanoparticules photoniques en fonction d'une intensité du champ magnétique; et à durcir la couche de composition pour produire la couleur structurelle afin d'immobiliser le pas de réseau des cristaux photoniques et afin de former une couche d'impression en couleur structurale.
(KO)제1 기판을 제공하는 단계; 상기 제1 기판 위에 자성 나노입자 및 경화성 물질을 포함하는 구조색 생성용 조성물 층을 형성하는 단계; 상기 구조색 생성용 조성물 층에 자기장을 인가함으로써, 상기 자기장의 세기에 따른 상기 자성 나노입자가 이루는 광결정의 격자 간격의 변화로 구조색을 발현시기는 단계; 및 상기 구조색 생성용 조성물 층을 경화시킴으로써, 상기 광결정의 격자 간격을 고정시켜 구조색 인쇄 층을 형성하는 단계를 포함하는 구조색 인쇄방법이 제공된다.
