Abstract
Abstract This invention relates to a sol of ultra-fine particles of layered structure material selected from a group of montmorillonite, hectorite, tetra-silicic mica and taeniolite, characterized in that said layered structure material is hydrophobed by treatment with organic material selected from a group of titanic acid ester; zirconic acid ester; silanes having one of methoxy-, ethoxy- and silanol-radicals and one of vinyl-, epoxy-, acryl- and amino-radicals; β-diketones mixed with lauryl amine; titanium amide; zirconium amide; and cationized silicone oil.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
120 words
A dispersion of ultra-fine particles of a layered structure material selected from the group consisting of montmorillonite, hectorite, tetra-silicic mica and taeniolite in an organic liquid, prepared by (a) cleaving the layered structure material into ultra-fine particles in an aqueous medium; (b) ion-exchanging hydratable ions of the ultra-fine particles with non-hydratable ions; (c) hydrophobing the ion-exchanged ultra-fine particles with an organic material selected from the group consisting of a titanic acid ester; a zirconic acid ester; silanes having one of methoxy-, ethoxy- and silanol-radicals and one of vinyl-, epoxy-, acryl- and amino-radicals; β-diketones mixed with lauryl amine; titanium amide; zirconium amide; and cationized silicone oil; (d) removing the aqueous medium; and (e) dispersing the hydrophobed particles in an organic liquid.
Claim 2
Dependent Claim
120 words
A dispersion of ultra-fine particles of a layered structure material selected from the group consisting of montmorillonite, hectorite, tetra-silicic mica and taeniolite in an organic liquid, prepared by (a) cleaving the layered structure material into ultra-fine particles in an aqueous medium; (b) ion-exchanging hydratable ions of the ultra-fine particles with non-hydratable ions; (c) hydrophobing the ion-exchanged ultra-fine particles with an organic material selected from the group consisting of a titanic acid ester; a zirconic acid ester; silanes having one of methoxy-, ethoxy- and silanol-radicals and one of vinyl-, epoxy-, acryl- and amino-radicals; β-diketones mixed with lauryl amine; titanium amide; zirconium amide; and cationized silicone oil; (d) removing the aqueous medium; and (e) dispersing the hydrophobed particles in an organic liquid.
Claim 3
Dependent Claim
64 words
A dispersion of ultra-fine particles of layered structure material in an organic liquid according to claim 1, wherein the non-hydratable ion used in the ion-exchange step (b) is selected from the group of K + , NH 4 + , Pb 2+ , Zn 2+ , Sn 2+ , Ba 2+ , Sr 2+ , Al 3+ , Sb 2+ and Bi 2+ .
Claim 4
Dependent Claim
24 words
A dispersion of ultra-fine particles of a layered structure material in an organic liquid according to claim 1, in combination with a synthetic resin.
