Abstract (en)

[origin: WO9422966A1] A composition comprising a colour pigment component and a light conditioning component characterized by being a transducing material having the ability to absorb light and reflect at least part of the light absorbed, thereby modifying the light in the coating resulting from the application of the composition. Such light conditioning component includes any material having the ability to partially absorb light. Preferred are neutral grey pigments in the form of grey powders having a minimal colour producing effect. The pigments can be in the form of ground grey powders such as powders taken from granite, feldspar, quartz or limestone or in the form of spherical metallic particles such as metallic zinc. In one embodiment the grey powder is in physical admixture with the colour pigments and serves to space the pigments apart from one another. In a variant the grey powder and the colour pigments are contained in respective superposed layers.
