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) &#x2265;40%, if 60&#x3c;L*&#x3c;100, or (ii) &#x2265;30%, if 30&#x3c;L*&#x2264;60, or (iii) &#x2265;20%, if 0&#x3c;L*&#x2264;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.

Coating system

The invention relates to a method of producing color pastes, in which a component comprising colorant particles is dispersed in a binder. In the method of the invention the dispersing operation is controlled by beaming excitational light of a defined wavelength range into a mixture of the component comprising colorant particles and the binder, detecting the light transmitted, reflected and/or scattered by the mixture and determining a sample spectrum, evaluating the sample spectrum and hence determining parameters of the color paste, and monitoring changes in the sample spectrum over time and terminating the dispersing operation when predetermined target parameters are attained.
