Abstract
A screen includes: a base material; and a pigmented layer provided on one surface of the base material, the pigmented layer including a first pigment that absorbs a visible light component contained in room light, and a second pigment that absorbs ultraviolet light, wherein the second pigment absorbs the ultraviolet light contained in sunlight, and varies the color imparted by a remaining visible light component unabsorbed by the first pigment absorbing the visible light component of the sunlight, the color being varied in such a manner as to reduce the absolute value of a color difference on a chromaticity diagram between a white point and a point indicative of the color imparted by the remaining component.

A screen comprising:
- a base material;
- and
- a pigmented layer provided on one surface of the base material,
- the pigmented layer including a first pigment that absorbs a visible light component contained in room light, and a second pigment that absorbs ultraviolet light, wherein the second pigment absorbs the ultraviolet light contained in sunlight, and varies the color imparted by a remaining visible light component unabsorbed by the first pigment absorbing the visible light component of the sunlight, the color being varied in such a manner as to reduce the absolute value of a color difference on a chromaticity diagram between a white point and a point indicative of the color imparted by the remaining component.
A screen comprising:
- a base material;
- and
- a pigmented layer provided on one surface of the base material,
- the pigmented layer including:
- a first pigment that absorbs a visible light component, the visible light component absorbed by the first pigment being a part of all visible light, and
- a second pigment that emits light of a waveband responsible for a complementary color of the color imparted by a remaining component unabsorbed by the first pigment.
