Claim 14
Dependent Claim
97 words
A process of forming a color filter array element comprising (a) image-wise heating a dye-donor element comprising a support having thereon a dye layer, and (b) transferring a dye layer to a dye-receiving element comprising a transparent support having thereon one or more polyesters having a Tg greater than about 200° C. derived from one or more dibasic aromatic acids and one or more dihydroxyphenols that contain at least one large bulky central moiety, said imagewise-heating being done in such a way as to produce a repeating pattern of colorants to form said color filter array element.
Claim 15
Dependent Claim
97 words
A process of forming a color filter array element comprising (a) image-wise heating a dye-donor element comprising a support having thereon a dye layer, and (b) transferring a dye layer to a dye-receiving element comprising a transparent support having thereon one or more polyesters having a Tg greater than about 200° C. derived from one or more dibasic aromatic acids and one or more dihydroxyphenols that contain at least one large bulky central moiety, said imagewise-heating being done in such a way as to produce a repeating pattern of colorants to form said color filter array element.
