US Patent:

7754409, Jul 13, 2010
Filed:

Jan 18, 2007
Appl. No.:

11/624335
Inventors:

Mridula Nair - Penfield NY, US
David C. Boris - Webster NY, US
Charles P. Lusignan - Rochester NY, US
Dennis J. Massa - Pittsford NY, US
Tamara K. Jones - Rochester NY, US
Anita M. Fees - Rochester NY, US
Assignee:

Eastman Kodak Company - Rochester NY
International Classification:

G03G 5/00
US Classification:

43013714, 43013715
Abstract:

The present invention is a method of manufacturing toner particles that includes providing a first emulsion of a first aqueous phase comprising a pore stabilizing hydrocolloid dispersed in an organic solution containing a polymer. The first emulsion is dispersed in a second aqueous phase to form a second emulsion that is sheared in the presence of a stabilizing agent to form droplets of the first emulsion in the second aqueous phase. The organic solution is evaporated from the droplets to form porous toner particles.

US Patent:

20050019745, Jan 27, 2005
Filed:

Jul 23, 2003
Appl. No.:

10/625428
Inventors:

Krishnan Chari - Fairport NY, US
Zhanjun Gao - Rochester NY, US
Joseph Sedita - Albion NY, US
Ramasubramaniam Hanumanthu - Rochester NY, US
Charles Lusignan - Rochester NY, US
International Classification:

C12Q001/00
US Classification:

435004000
Abstract:

A method for making an element containing an array of microspheres on a support, the method comprising the steps of: coating a support with a coating composition to form a receiving layer with a modifiable elastic modulus; coating on the receiving layer a dispersion of microspheres in a carrier fluid; modifying the modulus to allow the microspheres to partially submerge into the intermediate layer; removing the fluid medium from the suspension of microspheres; and fixing the microspheres on the receiving layer so that the element can withstand wet processing.

B05D003/00
US Classification:

435006000, 435287200, 427002110
Abstract:

An element containing an array of microspheres on a support is described, and a method of making the element, wherein the method includes coating a support with a coating composition to form a receiving layer with a modifiable elastic modulus; coating on the receiving layer a dispersion of microspheres in a fluid suspension; modifying the modulus of the receiving layer to allow the microspheres to partially submerge into the receiving layer; removing the fluid suspension from the receiving layer; and fixing the microspheres in the receiving layer so that the element can withstand wet processing.

US Patent:

20060134799, Jun 22, 2006
Filed:

Dec 22, 2004
Appl. No.:

11/021120
Inventors:

Ravi Sharma - Fairport NY, US
Charles Lusignan - Rochester NY, US
International Classification:

G01N 33/50
US Classification:

436174000, 436500000
Abstract:

Methods and apparatuses are provided for assembling a structure on a support having a pattern of binding sites. In accordance with the method, a first fluid is provided on the surface of the support with the first fluid being of a type that that increases viscosity when cooled, the first fluid having first micro-components suspended therein each adapted to engage the binding sites. First fluid proximate to selected binding sites is cooled to increase the viscosity of the responsive fluid proximate to the selected binding sites so that the first micro-components suspended in the first fluid are inhibited from engaging the selected binding sites.

US Patent:

20120077000, Mar 29, 2012
Filed:

Sep 24, 2010
Appl. No.:

12/889716
Inventors:

David D. Putnam - Fairport NY, US
Mridula Nair - Penfield NY, US
Joseph S. Sedita - Albion NY, US
Charles P. Lusignan - Rochester NY, US
Po-Jen Shih - Webster NY, US
International Classification:

G03G 13/20
B32B 5/16
B32B 3/10
US Classification:

428207, 399320
Abstract:

A process of producing an image including transferring porous polymeric marking particles to a receiver, and fixing the marking particles to the receiver by applying heat and pressure by contacting the marking particles with a heated fuser member including a topcoat layer having a storage modulus of at least 10 MPa at 175 C. In particular embodiments, the invention is specifically directed towards fusing porous toner materials, and enables reducing the image relief, toner spread, and differential gloss of resulting fused toner images. Higher gloss and reduced differential gloss is obtained at similar or reduced toner spread, measured by toner particle area gain, allowing the use of reduced fusing conditions compared to solid toners.
