Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
A dye-donor element for thermal dye transfer comprising a support having on one side thereof a dye dispersed in a polymeric binder, characterized in that said polymeric binder comprises a mixed cellulose ester and said dye-donor element contains a colorless, non polymeric material for increasing dye transfer efficiency having the following formula: wherein both R groups represent -CO₂J or -O₂CJ and are located either ortho or meta to each other; and each J independently represents a substituted or unsubstituted phenyl group, or a substituted or unsubstituted carbomonocyclic or carbobicyclic ring having from 5 to 12 carbon atoms, with the proviso that when either or both of J is substituted, then the total number of substituent carbon atoms in each J group is 8 or less.
Claim 2
Dependent Claim
125 words
A dye-donor element for thermal dye transfer comprising a support having on one side thereof a dye dispersed in a polymeric binder, characterized in that said polymeric binder comprises a mixed cellulose ester and said dye-donor element contains a colorless, non polymeric material for increasing dye transfer efficiency having the following formula: wherein both R groups represent -CO₂J or -O₂CJ and are located either ortho or meta to each other; and each J independently represents a substituted or unsubstituted phenyl group, or a substituted or unsubstituted carbomonocyclic or carbobicyclic ring having from 5 to 12 carbon atoms, with the proviso that when either or both of J is substituted, then the total number of substituent carbon atoms in each J group is 8 or less.
