A substrate containing magnesium treated with color development, according to the present invention, comprises a coating having a structure in which crystals having a plate-shaped structure are horizontally even and densely stacked on a matrix containing magnesium, thereby maintaining a texture and sheen unique to the metal while enabling even development of a plurality of colors on the surface by controlling the average thickness of the coating, according to the amount of stacking of the crystals, and thus can be useful in areas using metal materials, such as external materials for construction, vehicle interiors, and especially in electrical and electronic parts material fields such as in mobile phone case parts. La présente invention porte sur un substrat contenant du magnésium traité avec développement de couleur, comprenant un revêtement ayant une structure dans laquelle des cristaux ayant une structure lamellaire sont empilés horizontalement de façon égale et dense sur une matrice contenant du magnésium, ce qui maintient de cette manière une texture et un lustre propres au métal tout en permettant le développement égal d'une pluralité de couleurs sur la surface par réglage de l'épaisseur moyenne du revêtement, selon la hauteur d'empilement des cristaux, et donc pouvant être utile dans des domaines utilisant des matériaux métalliques, tels que des matériaux externes pour la construction, des intérieurs de véhicules, et en particulier dans les domaines des matériaux pour des pièces électriques et électroniques tels que dans des parties de boîtier de téléphone mobile. 마그네슘을 포함하는 발색 처리된 기재는, 마그네슘을 포함하는 매트릭스 상에 판상 구조의 결정이 수평적으로 균일하고 조밀하게 적층된 구조의 피막을 포함함으로써, 금속 고유의 질감 및 광택성을 유지할 수 있을 뿐만 아니라, 상기 결정의 적층되는 정도에 따른 피막의 평균 두께 제어를 통하여 표면에 다양한 색상을 균일하게 구현할 수 있으므로, 금속재가 사용되는 건축 외장재, 자동차 인테리어, 특히 모바일 제품 프레임 등의 전기·전자 부품소재 분야에서 유용하게 사용될 수 있다.
