US Patent:

20030094120, May 22, 2003
Filed:

Aug 26, 2002
Appl. No.:

10/227285
Inventors:

Christopher Golley - Sandersville GA, US
Daniel Panfil - Milledgeville GA, US
Harry Brown - Sandersville GA, US
John Husband - Cornwall, GB
Assignee:

IMERYS PIGMENTS, INC.
International Classification:

C09C001/42
D21H019/40
US Classification:

106/486000, 106/484000, 162/181800
Abstract:

A pigment product suitable for use in a coating composition to provide a gloss coating on paper, the pigment product comprising a processed particulate kaolin produced from a naturally platy kaolin clay having a particle size distribution such that about 50% to 60% by weight of the particles have an esd less than 2 m and less than 25% by weight of the particles have an esd less than 0.25 m and a shape factor of at least 15. In processing, the crude kaolin is ground to a shape factor greater than 50 to produce even greater “platy” clay. The pigment product has a particle size distribution such that at least 80% by weight of the particles have an esd less than 2 m and greater than 12% and less than 35% by weight of the particles have an esd less than 0.25 m and whose surface area is greater than 12 m/g when measured by the BET method.

Filed:

Aug 8, 2002
Appl. No.:

10/214359
Inventors:

Robert Pruett - Milledgeville GA, US
Jun Yuan - Warner Robins GA, US
Christopher Golley - Sandersville GA, US
Michael Garska - Sandersville GA, US
Assignee:

Imerys Pigments, Inc.
International Classification:

B03B001/00
B03D003/06
US Classification:

209/005000, 106/486000, 501/146000, 210/723000
Abstract:

The present invention provides an improved method of beneficiating and dewatering kaolin clays. The product of the improved process is a brightened, dewatered kaolin, suitable for use in pigments and paper coating compositions. The improved beneficiation process provides refined kaolin for pigments and other purposes of the same or better quality as prior art processes, but with the use of fewer steps and materials, at significant cost and environmental savings.

US Patent:

20030164117, Sep 4, 2003
Filed:

Dec 20, 2002
Appl. No.:

10/324019
Inventors:

Christopher Golley - Sandersville GA, US
John Manasso - Roswell GA, US
International Classification:

C09D011/00
C04B014/04
D21H011/00
US Classification:

106/486000, 106/031600, 162/162000
Abstract:

The present invention provides kaolin clay pigments having at least the following characteristics: Brightness (GE): at least about 89.0; Shape Factor: at least about 30; Brookfield viscosity, measured at 20 rpm and at less than or equal to about 65% solids: about 100 to about 700 centipoise; and Hercules viscosity, measured at 18 dynes and at less than or equal to about 65% solids: about 200 rpm to about 1000 rpm. Preferred kaolin sources include Brazilian kaolins, especially Rio Capim kaolins. The kaolin pigments of the present invention possess a combination of optical and physical properties, such as brightness, printability, and transfer efficiency, not previously seen in existing commercial products. They are useful, e.g., in paper filler and coating compositions, ink compositions, and printing applications, especially rotogravure printing.

US Patent:

20030202929, Oct 30, 2003
Filed:

Sep 26, 2002
Appl. No.:

10/254553
Inventors:

Christopher Golley - Sandersville GA, US
International Classification:

D06L001/00
US Classification:

423/419100
Abstract:

Bleaching a particulate calcium carbonate aqueous slurry with a reductive bleaching agent such as formamidine sulfinic acid increases the viscosity of the slurry. Combining the slurry with a metal material such as strontium hydroxide reduces any increase in viscosity of the bleached calcium carbonate slurry. Addition of the reductive bleaching agent and/or the metal material takes place prior to, during or after the manufacture of the slurry or the bleaching step. Metal materials in one embodiment include those that form substantially water insoluble precipitates of the reductive bleaching reaction products.
