Bayer Corporation - Pittsburgh PA
E.I. DuPont De Nemours and Company - Wilmington DE
International Classification:
C09B 6750
US Classification:
524 88, 106410, 106411, 106412, 106413, 106493, 106494, 106495, 106496, 106497, 106498
Abstract:
This invention relates to a process for preparing conditioned organic pigments by (a) milling a mixture comprising: (1) one or more crude organic pigments; (2) at least about 0. 1% by weight, relative to the organic pigment, of one or more acrylic copolymer dispersants; and (3) 0 to about 100 parts by weight, relative to the organic pigment, of a milling liquid in which the organic pigment is substantially insoluble; and (b) isolating the milled organic pigment.

Aqueous Graft Copolymer Pigment Dispersants

View page
US Patent:
6599973, Jul 29, 2003
Filed:
Sep 27, 2000
Appl. No.:
09/670359
Inventors:
Karyn B. Visscher - Voorhees NJ
Patrick F. Mc Intyre - West Chester PA
Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
International Classification:
C08L 5100
US Classification:
524504, 524413, 524425, 524430, 524431, 524441, 524445, 524451, 524533, 524535, 524547, 524556, 524558
Abstract:
A polymeric dispersant for pigments based on an acrylic graft copolymer wherein the graft copolymer has a weight average molecular weight of about 5,000-100,000 and comprises a hydrophobic polymeric backbone and discrete anionic and nonionic hydrophilic side chains attached to the backbone. These graft copolymers are useful as dispersants in aqueous systems, and are particularly useful in formulating exterior water borne coatings for automobiles and trucks.

Metallic Flake Containing Coating Compositions Having Improved Glamour

View page
US Patent:
6646070, Nov 11, 2003
Filed:
Apr 9, 2001
Appl. No.:
09/828748
Inventors:
Charles T. Berge - Wilmington DE
Michael Fryd - Philadelphia PA
Josef Huybrechts - Oud-Turnhout, BE
Kenneth S. Kirshenbaum - West Bloomfield MI
Karyn B. Visscher - Voorhees NJ
Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
International Classification:
C08F 470
US Classification:
526115, 524441
Abstract:
This invention provides for an aqueous metallic flake containing coating composition having improved glamour. The coating composition includes a neutralized phosphated segmented copolymer dispersed in an aqueous carrier. The phosphorous moiety in the segmented copolymer passivates the metallic flakes, such as aluminum flakes, used to produce the glamour. As a result, generation of hydrogen gas is substantially reduced. The segmented copolymer is provided with hydrophobic and nonionic hydrophilic segments. Applicants have discovered that by including a nonionic hydrophilic segment in the segmented copolymer, glamour of the resultant coating composition can be improved. Furthermore, by controlling the molar ratio of the hydrophobic segment to the hydrophilic segment in the segmented copolymer and the solubility parameter of the hydrophobic segment, applicants have discovered that it is possible to use either a non-passivated aluminum flake or pre-passivated aluminum flake in the coating composition while improving glamour over conventional metallic paints and still maintaining the dispersion stability of the composition. As a result, formulator has substantial leeway in selecting from a wide array of environmentally acceptable solvents, film forming binders and components, which are typically added to a coating composition for improving the coating properties. The composition is most suited for use in automotive OEM and refinish metallic paints.

Aqueous Coating Compositions Having Improved Transparency

Inventors:
Patrick F. McIntyre - West Chester PA
Karyn B. Visscher - Voorhees NJ
Kenneth S. Kirshenbaum - West Bloomfield MI
Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE

US Classification:
524441, 524523, 524538, 524556, 524562, 524599, 524515
Abstract:
Transparent iron oxide pigment dispersions which produce waterborne coating compositions having excellent transparency and reduced haze are provided. The dispersions contain dispersed pigment, an aqueous carrier, and a mixture of water-dispersible acrylic copolymer dispersants, the mixture containing at least one acrylic copolymer dispersant having acid functional groups, at least one acrylic copolymer dispersant having phosphate functional groups, and optionally at least one acrylic copolymer dispersant having alkyl amino groups and preferably benzyl groups in the pigment anachoring segment. Such pigment dispersions are useful in forming automotive waterborne paints, particularly âmetallicâ automotive paints.

Methods For Forming Patterns On A Filled Dielectric Material On Substrates

View page
US Patent:
7259443, Aug 21, 2007
Filed:
Jun 25, 2004
Appl. No.:
10/877739
Inventors:
Karyn B. Visscher - Voorhees NJ, US
Assignee:
E.I. du Pont de Nemours and Company - Wilmington DE
International Classification:
H01L 29/06
H01L 23/48
US Classification:
257618, 257763, 257E23003
Abstract:
Methods of forming a pattern of filled dielectric material on a substrate by thermal transfer processes are disclosed comprising exposing to heat a thermally imageable donor element comprising a substrate and a transfer layer of dielectric material. The exposure pattern is the image of the desired pattern to be formed on the substrate, such that portions of the layer of dielectric material are transferred onto the substrate where the electronic device is being formed. The filled dielectric material can be patterned onto a gate electrode of a thin film transistor. The pattern dielectric material may also form an insulating layer for interconnects. Donor elements for use in the process are also disclosed. Methods for forming thin film transistors and donor elements for use in the thermal transfer processes are also disclosed.
