ABSTRACT:
A dispersion comprising hydrotalcite compound particles having(1) an average secondary particle diameter of 0.1 to 3 μm as measured by a laser beam diffraction scattering method,(2) a specific surface area of 0.5 to 10 m2/g as measured by a BET method, and(3) a platy crystal particle shape, and an organic polar solvent; and a dope for polyurethane or aromatic polyamide article.The present invention has made it possible to provide hydrotalcite compound particles having superior affinity to and dispersibility in organic polar solvents, and a dope having the above particles dispersed therein uniformly, used for production of polyurethane or aromatic polyamide article.
