摘要:
This specification relates to a decoration member comprising: a substrate; a pattern layer comprising two or more unit pattern provided on one surface of the substrate; and an inorganic layer formed on the pattern layer, in which the inorganic layer comprises a region in which a thickness t(x) of the inorganic layer formed on each unit pattern increases in a direction x in which the unit patterns are arranged.
技术问题语段:
When expressing heterogeneous colors on a single surface, the color should be printed two or more times, and when it is desired to apply a variety of colors to a three-dimensional pattern, it is practically difficult to implement the expression of the colors.|Further, in the existing decoration film, the color is fixed according to a viewing angle and even though there is a slight change, the change is limited to a difference degree of the color sense.
权利要求:
1. A decoration member comprising: a pattern layer comprising two or more unit patterns; and an inorganic layer formed on the pattern layer, wherein the inorganic layer comprises a region in which a thickness t(x) of the inorganic layer formed on each of the two or more unit patterns increases in a direction x in which the unit patterns are arranged, wherein the unit pattern is a unit prism pattern, wherein the prism pattern has a ridge line in a first direction and is continuously arranged in a second direction perpendicular to the first direction, wherein the inorganic layer comprises a unit inorganic layer provided on each of unit prism pattern, and wherein an average thickness of the unit inorganic layer provided on any one unit prism pattern is different from the average thickness of the unit inorganic layer provided on another unit prism pattern arranged adjacent to the unit prism pattern.
2. The decoration member of claim 1, wherein the area where the thickness t(x) of the inorganic layer increases comprises at least one of an area where the thickness continuously increases, and an area where the thickness discontinuously increases.
