Abstract
An organic-inorganic composite is useful as a sheeted filler having a high aspect ratio. A positively charged organic compound is intercalated into a non-swelling layered silicate that is composed of mica and has K ions between the layers, and has primary particles of 2 μm to 500 μm as an average particle size. The layered silicate is represented as the formula: (KM)(XY)(SiAl)O(OHF), wherein 0.6≦a≦1.0, 0≦b≦0.1, 1.0≦c≦3, 0≦d≦2, 2≦c+d≦3, 0≦e≦4, 0≦f≦2; M is a cation other than K which is between layers and at least one of Li, Na, Rb, Cs, NH, Be, Mg, Ca, Sr, Ba, Mn, Fe, Ni, Cu, Zn and Al; X and Y are metals enclosed in an octahedral formed in a 2:1 typed sheet; X is at least one of Mg, Fe, Mn, Ni, Zn and Li; and Y is at least one of Al, Fe, Mn and Cr.
