Title:
MULTILAYERED COATING FILM AND COATED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2022/102380
Kind Code:
A1
Abstract:
This multilayered coating film comprises: a photoluminescent layer formed directly or indirectly on a surface of an object being coated, the photoluminescent layer containing a photoluminescent material; and a translucent coloring layer stacked on top of the photoluminescent layer, the coloring layer containing a red coloring material. The photoluminescent layer has an L*(θ) of less than or equal to 10 at 45° ≤ θ ≤ 80° and 100° ≤ θ ≤ 110°, where L*(θ) is the value of a brightness index L* of reflected light measured at a light receiving angle (angle of tilt from the direction of specular reflection toward the light source side) θ when the angle of incidence of light (angle to the normal to the plane of the photoluminescent layer) is 45°. When the photoluminescent material is projected onto the bottom surface of the photoluminescent layer, the ratio of the projected area of the photoluminescent material is 3%-70% inclusive per unit area of the bottom surface.
