Abstract

A coating formed on a substrate is provided which coating comprises (a) an organic NIR-transparent pigment and/or an inorganic NIR-reflective pigment; (b) a dye having a transmittance of at least 75% in the range of from 700 to 2500 nm; and (c) optionally an effect pigment; wherein said coating exhibits a total solar reflectance (TSR) of (i) ≥40%, if 60<L*<100, or (ii) ≥30%, if 30<L*≤60, or (iii) ≥20%, if 0<L*≤30, wherein L* is the lightness. The coating is suitable for an exterior-use coating like an industrial coating or a coating for vehicles, especially an automotive finish, having improved jetness.
