Filed:

Jul 1, 2005

Appl. No.:

11/173595

Inventors:

James Walter Wheeler - West Chester PA, US
John Stephen Locke - Hockessin DE, US
Samit N. Chevli - Hockessin DE, US
Sandra Laurine Issler - Newark DE, US
Alicia Marie Walsh - Wilimingon DE, US

Assignee:

E. I. du Pont de Nemours and Company - Wilmington DE

International Classification:

C09D 11/02
B41J 2/01

US Classification:

106 3127, 347100

Abstract:

The present invention pertains to a dye-based inkjet ink set and, more particularly, to a dye-based inkjet ink set suitable for printing on polyamide fabric. The present invention also pertains to a method for printing a polyamide fabric with the dye-based inkjet ink set, and a polyamide fabric so printed.

MARK A HACKLER - OCEAN NJ, US

International Classification:

B41C 1/00
G03F 7/20

Abstract:

The invention pertains to a photosensitive element, particularly a photopolymerizable printing form precursor; a method of preparing the photosensitive element to form a printing form for use in relief printing; and, a process of making the photosensitive element. The printing form precursor includes a layer of a photosensitive composition, a digital layer that is adjacent to a side of the photosensitive layer, and a cell pattern layer that is disposed between the photosensitive layer and the digital layer. The cell pattern layer includes a plurality of features in which each feature an area between 5 to 750 square microns and is composed of an ink that is opaque to actinic radiation and transparent to infrared radiation. Since the cell pattern layer is integral with the printing form precursor, digital imaging can occur rapidly with relatively low resolution optics to form a mask without needing to also form a microcell pattern of the digital layer. The printing form precursor having the integrated cell pattern layer facilitates the preparation of relief printing forms to have a print surface suitable for printing solids with uniform, dense coverage of ink.
