Abstract:
1. A flat element having a dark surface and exhibiting a reduced solar absorption, the flat element comprising: a) a substrate whose reflection in the visible light range from 380 to 720 nm is less than 50% and in the near-infrared range from 720 to 1500 nm exceeds 60%, wherein said substrate is a fibrous material, wherein the fibrous material is selected from the group consisting of: artificial leather and natural leather; and b) at least one coating, the coating comprising: a binder which in the spectral range of 380 to 1500 nm has a transparency exceeding 70%; and a first pigment which imparts in the visible light range from 380 to 720 nm a reflection of the coating less than 50% and in the spectral range of the near-infrared range from 720 to 1500 nm a transparency exceeding 50%, wherein the particle size of said first pigment is smaller than 0.9 μm and said first pigment is selected from the group consisting of: organic pigments, azo pigments, monoazo, disazo, β-naphtol, naphtol AS, lacquered azo, benzimidazolon, disazo condensation, metal complex, isoindolinon and isoindolin pigments, polycyclic pigments, phthalocyanine, chinacridon, perylene, perinon, thioindigo, anthraquinone, anthrapyrimidin, flavanthrone, pyranthrone, anthanthrone, dioxazine, triarylcarbonium, chino-phthalone, and diketo-pyrrolo-pyrrole pigments.
