METHODS OF PHOTOPROTECTING A MATERIAL AGAINST SOLAR UV RADIATION USING PHOTONIC PARTICLES; COMPOSITIONS

WIPO Patent Application WO/2011/045740

A3

The present invention provides a method of photoprotecting a material against solar UV radiation, consisting in treating said material using a composition comprising a dispersion of photonic particles with a mean size in the range 1 μm to 500 μm, each comprising a diffracting arrangement of monodisperse nanoparticles or voids, the diffraction spectrum of said arrangement including a first order reflection peak in the wavelength range 250 nm to 400 nm, or consisting in integrating said dispersion of photonic particles into said material. In particular, the present invention provides methods of photoprotecting materials such as paints, inks, coatings, materials manufactured from polymers, or fibrous materials such as textiles, papers, or organic or mineral glasses.
