FIELD: chemistry. ^ SUBSTANCE: described is a coloured coating composition containing a white primary paint and at least one colouring pigment in a form which can be easily mixed with the white primary paint. The white primary paint contains a film-forming polymer, a liquid carrier, one or more opaque white pigments and one or more filling materials. The coloured coating composition has light reflection coefficient Y less than 110 and greater than a value defined from the equation Y=mC+K, where 25>C>1.0, C is colour saturation of the coloured coating composition, m and K are empirical coefficients selected according to the type and number of types at least one colouring pigment and depend on the hue angle of the coating composition. ^ EFFECT: composition for applying on building surfaces makes said surfaces lighter than when using existing paints with close colour saturation. ^ 7 cl, 2 dwg, 10 tbl |
