摘要：The present invention relates to a composite particle containing a solidinorganic or organic colorless support material and adherent to it an inorganic and/ororganic pigment particle, wherein the pigment particle has an average particle size of 1nm to 100 nm, comprises at least one primary pigment particle and the minimum averagedistance between two pigment particles is at least one quarter of the diameter of theprimary pigment particle, whereby the modified inorganic and organic pigments,depending on the pigment material, can be used as IR light absorbers or as color-imparting agents and give rise to a negligible haze in the matrix.
