COATING COMPOSITION AND COATING FILM
Document Type and Number:
WIPO Patent Application WO/2024/095572
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to provide a coating composition which is capable of forming a display that can exhibit high retroreflective performance (especially, retroreflective performance at a high incidence angle) without being misidentified as a white line even in cases where the display is formed on a road surface. A coating composition according to the present disclosure is for a detection object to be sensed with near-infrared light, and contains a coating film-forming resin (A), a color pigment (B) and aggregate (E). The color pigment (B) comprises at least one pigment that is selected from the group consisting of a white color pigment having a near-infrared reflectance of 60% or more, a chromatic color pigment having a near-infrared reflectance of 50% or more, and a black color pigment having a near-infrared reflectance of 30% or more, if the reflectance in the wavelength range from 800 nm to 2,500 nm is taken as the near-infrared reflectance; and the aggregate (E) contains aggregate (E1) which has a near-infrared reflectance of 5% or more.
