FIELD: chemistry.
SUBSTANCE: coloured composition contains particulate material which scatters radiation in the near-infrared region and one or more colouring substance. The particulate material and colouring substance are dispersed. Said material is selected from titanium dioxide, doped titanium dioxide and combinations thereof, and has average crystal size greater than 0.40 mcm, and particle size distribution where 30% or more particles are smaller than 1 mcm. Material consisting of titanium dioxide particles can be used for adding to the coloured composition, said material having a coating which contains one or more oxide materials, which provides low levels of photocatalytic activity of titanium dioxide.
EFFECT: invention increases reflection of radiation in the near-infrared region, while simultaneously reducing reflection of visible light of dark or intensely coloured compositions.
