Claims29
A recording component comprising a transparent substrate situated between a hydrophilic ink receiving layer and a colorant hydrophobic luminescent layer wherein said ink receiving layer contains an ink spreading compound;
- and further wherein said hydrophobic luminescent layer contains a luminescent component which comprises an inorganic phosphor, an organic phosphor, a polymeric phosphor, a liquid crystalline nitrile or a liquid crystalline isothionitrile.
A recording component in accordance with claim 9 wherein the lightfastness component is (1) octyl salicylate, (2) hexadecyl-3,5-ditert-butyl-4-hydroxy-benzoate, (3) 4-allyloxy-2-hydroxy benzophenone;
- (4) 2-(4-benzoyl-3-hydroxyphenoxy) ethylacrylate, (5) 2-dodecyl-N-(1,2,2,6,6-pentamethyl-4-piperidinyl)succinimide, or (6) poly[N,N-bis(2,2,6,6-tetramethyl-4-piperidinyl)-1,6-hexane diamine-co-2,4-dichloro-6-morpholino-1,3,5-triazine).
A recording component consisting essentially of a transparent substrate situated between a hydrophilic ink receiving layer and a colorant hydrophobic luminescent layer wherein said ink receiving layer contains an ink spreading compound;
- and further wherein said hydrophobic luminescent layer contains a luminescent component which comprises an inorganic phosphor, an organic phosphor, a polymeric phosphor, a liquid crystalline nitrile, or a liquid crystalline isothionitrile.
