FIELD: chemistry.
SUBSTANCE: present invention pertains to a dispersion of fine indium oxide particles, doped with tin, which can be used for making an interlayer film for laminated glass. The technical outcome of the invention is regulation of the degree of adhesion at the boundary between the glass and the interlayer film, increased transparency and improved heat-shielding properties of laminated glass. The dispersion contains fine indium oxide particles, doped with tin, a plasticiser, organic solvent, containing alcohol as the main component, and a dispersion stabiliser. If concentration of fine indium oxide particles, doped with tin, is 0.7% of the mass, and optical path length of the glass cell is 1 mm, the dispersion has visible light transmission coefficient of 80% or more. Solar radiation transmission coefficient of the dispersion, for wavelength ranging from 300 nm to 2100 nm, is 3/4 or less of the visible light transmission coefficient. Turbidity is 1.0% or less, and yellowness index is 20 or more.
EFFECT: regulation of the degree of adhesion at the boundary between the glass and the interlayer film, increased transparency and improved heat-shielding properties of laminated glass.
