Claims
- 1. A latex composition comprising, as a rheology modifier, a boehmite alumina having a crystallite size (020 plane) of less than about 60 Angstroms and a surface area, when calcined to gamma phase, of greater than about 250 m.sup.2 /g, said boehmite alumina being present in an amount of from about 0.1 to about 5% by weight of said latex composition and being of a type that does not require acid for dispersibility.
- 2. The composition of claim 1 wherein said latex composition comprises a latex paint.
- 3. The composition of claim 2 including an additional rheology modifier.
- 4. The composition of claim 3 wherein said additional rheology modifier comprises a cellulosic thickener.
- 5. The composition of claim 4 wherein said additional rheology modifier comprises hydroxyethyl cellulose.
- 6. The composition of claim 3 wherein said additional rheology modifier comprises an inorganic material that exhibits rheological properties in an aqueous medium.
- 7. The composition of claim 6 wherein said additional rheology modifier comprises a clay.
- 8. The composition of claim 3 wherein said additional rheology modifier comprises a polymeric material dispersed in a water-compatible carrier liquid.
- 9. The composition of claim 1 wherein said boehmite alumina has a crystallite size of less than about 40 Angstroms.
