Abstract
An apparatus and method for creating color images which are coated with a composition including a lightfastness inducing material and a hydrophobic polymeric binder which protects the images from rough handling and degradation from exposure to UV radation in the light.
Claims4
Apparatus for creating color toner images, said apparatus comprising:
- means including a plurality of developer housings for forming color toner images on a charge retentive surface;
- means including a developer housing for depositing a composition comprising a scratch resistant polymer material and a lightfastness inducing material on said charge retentive surface prior to the formation of said color toner images thereon, said lightfastness material comprising a UV absorber selected from the group consisting of 2-(4-benzoyl-3-hydroxyphenoxy) ethylacrylate;
- 1,2-hydroxy-4-(octyloxy) benzophenone;
- poly[2-(4-benzoyl-3-hydroxyphenoxy) ethylacrylate];
- hexadecyl 3,5-di-tert-butyl-4-hydroxybenzoate;
- poly[N,N-bis(2,2,6,6-tetramethyl-4-piperidinyl)-1;
- 6-hexanediamine-co-2, 4-dichloro-6-morpholino-1,3,5-triazine);
- 2-dodecyl-N-(2,2,6,6-tetramethyl-4-piperidinyl) succinimide;
- 2-dodecyl-N-(1,2,2,6,6-pentamethyl-4-piperidinyl) succinimide;
- N-(1-acetyl-2,2,6,6-tetramethyl-4-piperidinyl)-2-dodecylsuccinimide;
- 1-[N-[poly(3-allyloxy-2-hydroxypropyl)-2-aminoethyl]-2-imidazolidinone;
- poly(2-ethyl-2-oxazoline) and an antioxidant;
- and
- means for fusing said color toner images and said scratch resistant material to a substrate.
