Abstract

The invention relates to a pigment composition in the form of an aqueous dispersion or slurry comprising: (a) porous aggregates formed by aggregation of colloidal primary particles of silica, aluminosilicate or a mixture thereof in an aqueous sol, said porous aggregates having a mean diameter from about 0.03 to about 25 ~m, and, (b) extender particles where the mean size of at least one dimension is larger than the mean diameter of the porous aggregates, wherein the weight ratio of porous aggregates to extender particles is from about 0.01:1 to about 3:1. The invention further relates to a process for its production, a compositionfor coating paper or paper board and a process for its production, and a process for coating paper or paper board and paper or paper board obtainable by the process.

Claims (14)

1. Pigment composition in the form of an aqueous dispersion comprising:
(a) porous aggregates formed by aggregation of colloidal primary particles of silica, aluminosilicate or a mixture thereof in an aqueous sol, said porous aggregates having a mean diameter from about 0.03 to about 25 µm, and, (b) extender particles where the mean size of at least one dimension is larger than the mean diameter of the porous aggregates, wherein the weight ratio of porous aggregates to extender particles is from about 0.01:1 to about 3:1.
2. Composition as claimed in claim 1, wherein the colloidal primary particles of silica or aluminosilicate have been formed from an aqueous solution of alkali metal silicate where alkali metal ions are removed through an ion exchange process or where the alkali metal silicate has been neutralised by the addition of an acid.
3. Composition as claimed in any one of the claims 1-2, wherein at least some of the porous aggregates are attached to extender particles.
4. Composition as claimed in any one of the claims 1-3, wherein the porous aggregates and the extender particles have opposite net charges.
5. Composition as claimed in any one of the claims 1-4, wherein the extender particles are of a material selected from the group consisting of kaolinites, smectites, talcites, calcium carbonate minerals, precipitated silica, gel-type silica, fumed silica, precipitated calcium carbonate, and mixtures thereof.
6. Composition as claimed in any one of the claims 1-5, wherein total content of porous aggregates and extender particles in the composition is from about 1 to about 60 wt%.
7. A process for the production of a pigment composition according to any one of the claims 1-6 comprising a step of mixing (a) an aqueous dispersion of porous aggregates formed by aggregation of colloidal primary particles of silica, aluminosilicate or a mixture thereof in an aqueous sol, said porous aggregates having a mean diameter from about 0.03 to about 25 µm, and, (b) extender particles where the mean size of at least one dimension is larger than the mean diameter of the porous aggregates, wherein the weight ratio of porous aggregates to extender particles is from about 0.01:1 to about 3.1.
8. A process for the production of a pigment composition according to any one of the claims 1-6 comprising the steps:

(a) mixing an aqueous sol comprising colloidal primary particles of silica or aluminosilicate and extender particles in a weight ratio primary particles of silica or aluminosilicate to extender particles from about 0.01:1 to about 3:1; and, (b) aggregating the colloidal primary particles of silica or aluminosilicate to form porous aggregates having a mean diameter from about 0.03 µm to about 25 µm, but not exceeding the mean size of the largest dimension of the extender particles.
9. Coating composition suitable for coating paper or paper board comprising a binder and a pigment composition according to any one of the claims 1-6.
10. Coating composition as claimed in claim 9, wherein the binder is selected from the group consisting of polyvinyl alcohols, optionally modified starches, gums, protein binders, latices and mixtures thereof.
11. A process for the production of a coating composition comprising a step of mixing a binder with a pigment composition according to any one of the claims 1-6.
12. A process for the production of coated paper or paperboard comprising a step of applying a coating composition according to any one of the claims 9-10 to at least one side of a paper or paperboard web.
13. A process as claimed in claim 12, wherein the coating is applied in an amount sufficient to yield from about 0.4 g/m2 to about 40 g/m2, of porous aggregates and extender particles from the pigment composition per coated side of the paper or paper board.
14. Paper or paper board obtainable by the process according to any one of the claims 12-13.
