Weak reflective materials

Abstract

The invention proposes, for example, a weakly reflective material with a low surface reflectivity coefficient and surface gloss. The weakly reflective material consists of at least a weakly reflective spray coating containing at least a binder, a pigment dispersed in the binder, and resin particles dispersed in the binder, and has a thickness of 3 to 100 µm, where the surface roughness RSm of a weakly reflective spray coating surface is 80 to 180 µm and the surface roughness Rsk of the surface is less than 0.5 µm. Ideally, the surface roughness Ra of the weakly reflective spray coating surface should be between 0.5 and 15.0 μni, and the surface roughness Rz of the surface should be between 3 and 70 pm.
