ANTIMONY PENTOXIDE BASED COMPLEX OXIDE FINE PARTICLE, COATING LIQUID FOR FORMING TRANSPARENCY COATING FILM CONTAINING THE FINE PARTICLE, AND BASE MATERIAL WITH TRANSPARENCY COATING FILM

摘要

PROBLEM TO BE SOLVED: To provide an antimony pentoxide based complex oxide fine particle which can form a transparency coating film in which there is no interference fringe, which excels in transparency and an antistatic characteristic, and which excels in adhesion with a base material, scratch resistance, scratch strength, pencil hardness or the like. SOLUTION: The antimony pentoxide based complex oxide fine particle includes: an antimony pentoxide fine particle whose average particle size is in the range of 5-50 nm; and a titanium oxide and/or zirconium oxide layer which has covered the surface of the fine particle. The antimony pentoxide based compound oxide fine particle includes: a chain-like antimony pentoxide fine particle in which an antimony pentoxide fine particle whose average particle size is in the range 5-50 nm connects in the shape of a chain, and an average connectivity number is in the range of 2-30; and a titanium oxide and/or zirconium oxide layer which has covered the surface of the fine particle. The antimony pentoxide fine particle contains a phosphorus oxide in the range of 0.1-15 wt.% as P2O5. COPYRIGHT: (C)2011,JPO&INPIT
