Robert Spahn - Webster NY, US

Assignee:

Eastman Kodak Company

International Classification:

C23C016/00

US Classification:

118/726000

Abstract:

A thermal physical vapor deposition source for vaporizing solid organic materials in forming an OLED on a structure includes a bias heater, an electrically insulative container disposed in the bias heater, and a vaporization heater disposed on the container. Relative motion is provided between the source and the structure to provide a substantially uniform organic layer on the structure.

Appl. No.:

8/976219

Inventors:

Luther C. Roberts - Rochester NY
Ching W. Tang - Rochester NY
Robert G. Spahn - Webster NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G02B 520

US Classification:

430 7

Abstract:

A method of making a color filter array on a first substrate is disclosed. The method includes depositing and patterning a photoresist layer on the substrate to form openings over selected regions of the substrate; providing a colorant layer having a heat transferable colorant material on a second substrate and positioning the second substrate such that the heat transferable colorant layer is in transferable relationship with but spaced a distance from the first substrate; heating the second substrate sufficiently to cause substantially all of the heat transferable colorant material to transfer across the spaced distance to the patterned photoresist layer on the first substrate; and removing the patterned photoresist layer leaving behind the heat transferable colorant material in the position of the openings over the selected regions of the first substrate.

International Classification:

G02B 520

US Classification:

430 7

Abstract:

A method of making a color filter array on a first substrate having an array of pixels is disclosed. The method includes depositing and patterning a photoresist layer on the substrate layer to form selected openings over pixels in the array; providing a colorant layer having a transferable colorant material on a second substrate and positioning the second substrate such that the transferable colorant material is in transferable relationship with the first substrate; transferring the colorant material to the photoresist layer on the first substrate; and removing the patterned photoresist layer leaving behind the colorant material in the position of the openings over the selected pixels.

Filed:

Jun 1, 1992

Appl. No.:

7/889827

Inventors:

Robert G. Spahn - Webster NY
Louis J. Gerenser - Webster NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G01N 27333

US Classification:

204416

Abstract:

A method is disclosed for producing Ag/Ni composite ion selective electrode on polymer substrates. By utilizing a nitrogen glow discharge pretreatment of the polymer substrate, silver may be deposited directly thereon. Further, because of the glow discharge pretreatment, aging of the silver layer prior to nickel deposition and bleaching operation is not necessary.

Appl. No.:

7/617458

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B21B 124
B29C 5102
B29C 5104
B29C 5114

US Classification:

156160

Abstract:

In the manufacture of a decorative sheet material to be bonded to a substrate to provide a surface having a brushed metal appearance, a light-reflective, glossy metal layer is formed on a thermoformable carrier film. A pattern of straight and parallel microscopic cracks is created in the metal layer at a temperature below Tg of the carrier film by bi-directionally bending and drawing the resulting sheet material around a straight cracking member. Thereafter, the sheet material is stretched at a temperature above Tg of the carrier film. This creates an attractive brushed metal appearance of reduced gloss.

Appl. No.:

9/070295

Inventors:

Charles D. DeBoer - Palmyra NY
Robert G. Spahn - Webster NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B41M 1055

US Classification:

430302

Abstract:

A direct write lithographic printing plate includes a base layer; a metal light absorbing layer provided over the base layer; and a melanophobic layer provided over the metal absorbing layer and selected to have a thickness which minimizes reflection of light from the metal layer so that light which passes through a selected portion of the melanophobic layer and into the metal light absorbing layer, is absorbed by such metal layer to provide a heat source which causes the removal, at the selected portion, of the melanophobic layer.

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03C 700
B41N 5035

US Classification:

430200

Abstract:

A donor element for laser color transfer processes includes a heat absorbing layer including a combination of a metal layer with an antireflecting layer having an index of refraction greater than 2. The heat absorbing layer may include a metal or an alloy either in single or multiple layers having a thickness sufficient to yield a heat capacity of less than 0. 2 calories per degree Centigrade per square meter and an optical density at the laser wavelength of 1. 0 or greater.
