Title:
PARTICLE-CONTAINING COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2020/246555
Kind Code:
A1
Abstract:
A particle-containing composition that contains inorganic particles (A) and particles (B) that are not the inorganic particles (A). The inorganic particles (A) are easily disintegrable inorganic particles (A1) that have an average particle diameter DA1 of 1–50 μm and a surface roughness Ra of 10–50 nm and/or inorganic particles (A2) that have an average particle diameter DA2 of less than 1 μm and an average primary particle diameter dA2 of 3–50 nm, and the other particles (B) have an average particle diameter DB of 1–50 μm and are coated with a polymer (C) that has a hydrogen-bond-accepting bond or a hydrogen-bond-accepting functional group. A production method for the particle-containing composition. A harmful air pollutant adhesion suppression method that uses the particle-containing composition.
