Modified carbon products and amphiphilic ions containing compositions

Abstract: A composition is disclosed which comprises a) an amphiphilic ion, and b) a modified carbon product comprising carbon having attached at least one organic group. The organic group has a charge opposite to the amphiphilic ion. Also disclosed are aqueous and non-aqueous ink and coating compositions incorporating this composition. Ink jet ink compositions are further described incorporating this composition.

Aqueous emulsion paints and pigment bases therefor

Abstract: IMPROVED AQUEOUS EMULSION TYPE PAINTS AND PIGMENT BASES THEREFOR ARE DESCRIBED IN WHICH THE PRINCIPAL OPACIFYING PIGMENT IS RUTILE TITANIA PIGMENT AND THERE IS ALSO INCORPORATED THEREWITH PRE 100 PARTS OF SAID RUTILE TITANIA PIGMENT BETWEEN ABOUT 1 AND ABOUT 20 PARTS BY WEIGHT, OF A SUBSTANTIALLY WATER-INSOLUBLE, HIGH MOLECULAR WEIGHT, CROSS-LINKED UREA-FORMALDEHYDE RESIN IN HIGHLY DISPERSED PARTICULATE FORM. SAID PARTICULATE UREA-FORMALDEHYDE RESIN IS CHARACTERIZED BY A BET SPECIFIC SURFACE AREA OF BETWEEN ABOUT 15 AND ABOUT 100 SQUARE METERS PER GRAM AND PREFERABLY HAS A VOLALITE CONTENT OF NOT OBER ABOUT 15% BY WEIGHT.

Carbon Black Reinforcement of Asphalts in Paving Mixtures

Abstract: Dispersion of submicrometre-size carbon black particles in asphalt at dosages of 11 to 16 percent by weight of asphalt has been found to improve the asphalt properties of durability, wear resistance, and temperature-viscosity susceptibility. This concept of reinforcing asphalts with a carbon black filler has been made practical by pelletizing the carbon black with a high-durability maltenes binder compatible with asphalts. The pellets are packaged in 11.34-kg (25 lb) polyethylene bags which are introduced, bag and all, into hot-mix cycle of asphalt concrete batch-type plants. In continuous-type plants, the pellets are added either through the asphalt feedline in correct proportion to the hot asphalt or through the hot aggregate feed in correct proportion to the hot aggregate. Since the carbon black becomes part of and bulks the asphalt, adjustments are made in batch weights to keep the volume relationship of binder to rock constant. Other design considerations are discussed. Effects of the carbon black addition on the properties of asphalts and asphalt concrete, as measured in both laboratory and field experiments, are shown. The present status of a continuing program of field testing and evaluation is described.

Toners containing chargeable modified pigments

Abstract: A toner composition is disclosed which contains the product of the mixture of resin particles and chargeable modified pigment particles. The chargeable modified pigment particles comprise at least one organic ionic group attached to the pigment particle and at least one amphiphilic counterion. The amphiphilic counterion has a charge opposite to that of the organic ionic group. Developer compositions containing the toner compositions of the present invention and methods of imaging are also described which use the toner compositions of the present invention.
