Abstract

A decoration member for a cosmetic container including: a color expression layer having a light reflecting layer and a light absorbing layer provided on the light reflecting layer; and a substrate provided on one surface of the color expression layer.

First claim

The invention claimed is:

1. A decoration member for a cosmetic container, the decoration member comprising:
a color expression layer comprising a light reflecting layer and a light absorbing layer provided on the light reflecting layer; and
a substrate for a cosmetic container provided on one surface of the color expression layer,
wherein the light absorbing layer comprises a metal oxynitride,
wherein the light reflective layer is in continuous contact with the light absorbing layer,
wherein a shape of an upper surface of the light reflective layer and a shape of an upper surface of the light absorbing layer are same,
wherein the light absorbing layer comprises one or more first regions wherein an upper surface of each of the one or more first regions has a first inclined surface having an inclination angle larger than 0° and 90° or less, and the light absorbing layer comprises one or more second regions wherein an upper surface of each of the one or more second regions has a second inclined surface,
wherein the second inclined surfaces have a different inclination direction from that of the first inclined surfaces, and have a different inclination angle from that of the first inclined surfaces, and
wherein a thickness of the one or more second regions is different from a thickness of the one or more first regions.

2. The decoration member of claim 1 , wherein the color expression layer further comprises a color film provided on a surface of the light reflecting layer opposite to a surface of the light reflecting layer facing the light absorbing layer, or on a surface of the light absorbing layer opposite to a surface of the light absorbing layer facing the light reflecting layer.

3. The decoration member of claim 1 , wherein the color expression layer further comprises a transparent substrate provided on a surface of the light reflecting layer opposite to a surface of the light reflecting layer facing the light absorbing layer, or on a surface of the light absorbing layer opposite to a surface of the light absorbing layer facing the light reflecting layer.

4. The decoration member of claim 1 , wherein the light absorbing layer has a dichroism of ΔE*ab>1, wherein ΔE*ab>1 is a distance in a space of L*a*b* in color coordinates CIE L*a*b* of the color expression layer.

5. The decoration member of claim 1 , wherein an upper surface of the light absorbing layer comprises a pattern having a protruding portion or a recess portion in the shape of a cone, a pattern having a protruding portion of which a highest point is formed as a line or a recess portion of which a lowest point is formed as a line, or a pattern having a protruding portion or a recess portion having a structure in which an upper surface is cut in a cone shape.

6. The decoration member of claim 5 , wherein the pattern having a protruding portion or the recess portion formed in the shape of a cone has a plurality of forms of which two or less forms have an identical shape when viewed from an upper surface of the pattern while rotating the pattern 360° around an apex of the cone.

7. The decoration member of claim 5 , wherein the pattern having the protruding portion of which the highest point is formed as the line or the recess portion of which the lowest point is formed as the line has a plurality of forms of a same shape when viewed from an upper surface of the pattern while rotating of the pattern 360° based on a center of gravity.

8. The decoration member of claim 1 , wherein the light absorbing layer has a refractive index of 0 to 8 at 400 nm.

9. The decoration member of claim 1 , wherein the light absorbing layer has an extinction coefficient of larger than 0 to 4 or less at 400 nm.

10. The decoration member of claim 1 , wherein the substrate for the cosmetic container comprises a plastic molding or a glass substrate for a cosmetic container.

11. The decoration member of claim 10 , wherein the plastic molding comprises one or more selected from polypropylene (PP), polystyrene (PS), polyvinyl acetate (PVAC), polyacrylate, polyethylene terephthalate (PET), polyvinyl chloride (PVC), polymethyl methacrylate (PMMA), ethylene-vinyl acetate copolymer (EVA), polycarbonate (PC), polyamide, and styrene-acrylonitrile copolymer (SAN).
