Claim 11

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 polycarbonate 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 glass support to said polycarbonate dye-receiving layer containing said dye image in a repeating mosaic pattern by use of an adhesive layer; and (e) removing said temporary support to expose one surface of said polymeric alignment layer, thereby forming said color filter array element, said adhesive layer comprising either (a) a polymer comprising the units of a linear polyester containing one or more substituted or unsubstituted aromatic diacids condensed with two or more substituted or unsubstituted aliphatic diols, said linear polyester having the formula: ##STR23## wherein: m is 100 to 90 mole %; n+p=m with the proviso that each of n and p is at least 20 mole %; and Q and R each independently represents a different substituted or unsubstituted difunctional linking group; or (b) a polymer comprising units of a linear polyester containing one or more substituted or unsubstituted aromatic diacids and one or more alicyclic diacids condensed with one or more aliphatic diols, said linear polyester having the formula: ##STR24## wherein m+k is 100 to 90 mole %; k is 5 to 50 mole %; n=m+k; and Z represents the atoms necessary to complete a 4-to 7-membered substituted or unsubstituted, saturated or monoethylenically unsaturated carbocyclic ring.

Claim 12

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 polycarbonate 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 glass support to said polycarbonate dye-receiving layer containing said dye image in a repeating mosaic pattern by use of an adhesive layer; and (e) removing said temporary support to expose one surface of said polymeric alignment layer, thereby forming said color filter array element, said adhesive layer comprising either (a) a polymer comprising the units of a linear polyester containing one or more substituted or unsubstituted aromatic diacids condensed with two or more substituted or unsubstituted aliphatic diols, said linear polyester having the formula: ##STR23## wherein: m is 100 to 90 mole %; n+p=m with the proviso that each of n and p is at least 20 mole %; and Q and R each independently represents a different substituted or unsubstituted difunctional linking group; or (b) a polymer comprising units of a linear polyester containing one or more substituted or unsubstituted aromatic diacids and one or more alicyclic diacids condensed with one or more aliphatic diols, said linear polyester having the formula: ##STR24## wherein m+k is 100 to 90 mole %; k is 5 to 50 mole %; n=m+k; and Z represents the atoms necessary to complete a 4-to 7-membered substituted or unsubstituted, saturated or monoethylenically unsaturated carbocyclic ring.
