Thermally-transferable fluorescent diphenylpyrazolines
First Claim
1. A donor element for thermal transfer comprising a support having on one side thereof a fluorescent diphenylpyrazoline compound dispersed in a polymeric binder, and on the other side thereof a slipping layer comprising a lubricant, said compound having the formula:
- ##STR7## wherein;
R is hydrogen;
cyano;
carboxyalkyl;
a substituted or unsubstituted alkyl group of 1 to about 6 carbon atoms;
or a substituted or unsubstituted aryl group of about 6 to about 10 carbon atoms; and
J is hydrogen;
a substituted or unsubstituted alkyl group of 1 to about 6 carbon atoms;
a substituted or unsubstituted aryl group of about 6 to 10 carbon atoms;
or may represent --CH2 -- or --CH2 CH2 -- to complete a 5- or 6-membered non-aromatic carbocyclic ring.
