Abstract
Abstract A process of preparing a color filter array element for use in making a color liquid crystal display device comprising: (a) overlaying a dye-receiving element with a dye-donor element, the dye-receiving element comprising a dimensionally-stable temporary support having thereon, in order, a polymeric alignment layer, a transparent conducting layer and a dye-receiving layer; (b) imagewise heating the dye-donor element to transfer a dye image in a repeating mosaic pattern to the dye-receiving layer; (c) removing the dye-donor element from contact with the dye-receiving element; (d) laminating a transparent permanent support to the dye-receiving layer containing the dye image in a repeating mosaic pattern; and (e) removing the temporary support to expose one surface of the polymeric alignment layer, thereby forming the color filter array element.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
129 words
A process of preparing a color filter array element for use in making a color liquid crystal display device comprising: (a) overlaying a dye receiving element with a dye-donor element, said dye-receiving element comprising a dimensionally-stable temporary support having thereon, in order, a polymeric alignment layer, a transparent conducting layer and a dye receiving layer; (b) imagewise heating said dye-donor element to transfer a dye image in a repeating mosaic pattern to said dye-receiving layer; (c) removing said dye donor element from contact with said dye receiving element; (d) laminating a transparent permanent support to said dye-receiving layer containing said dye image in a repeating mosaic pattern; and (e) removing said temporary support to expose one surface of said polymeric alignment layer, thereby forming said color filter array element.
Claim 2
Dependent Claim
129 words
A process of preparing a color filter array element for use in making a color liquid crystal display device comprising: (a) overlaying a dye receiving element with a dye-donor element, said dye-receiving element comprising a dimensionally-stable temporary support having thereon, in order, a polymeric alignment layer, a transparent conducting layer and a dye receiving layer; (b) imagewise heating said dye-donor element to transfer a dye image in a repeating mosaic pattern to said dye-receiving layer; (c) removing said dye donor element from contact with said dye receiving element; (d) laminating a transparent permanent support to said dye-receiving layer containing said dye image in a repeating mosaic pattern; and (e) removing said temporary support to expose one surface of said polymeric alignment layer, thereby forming said color filter array element.
