摘要:
An inkjet recording element is disclosed having a support and, on the support, (a) a porous base layer comprising particles of fumed silica and a hydrophilic binder and (b) a porous gloss layer above the base layer comprising particles of colloidal silica and a hydrophilic binder, wherein the particles of fumed and colloidal silica are anionic. Also disclosed is a method of printing on such an inkjet recording element. The inkjet recording element can potentially have, in some embodiments, the advantages of improved image quality (reduced coalescence) and higher dye ink optical densities.

摘要:
A process for laminating an ink jet print having the steps of: a) providing an ink jet print having a support having thereon an ink jet image; b) contacting the imaged surface of the ink jet print with a transfer laminating element to form a composite, the transfer laminating element having a flexible, polymeric support having thereon a protection layer of a water-dispersible, hydrophobic polyester resin having the following general formula: In-P-Am wherein I is an ionic group; n is an integer from 1-3; P is a polyester backbone; A is an aliphatic group having a straight or branched chain fatty acid or triglyceride thereof halving from about 6 to about 24 carbon atoms; and m is an integer from 3-8; c) applying heat and pressure to the composite to transfer the layer on top of the ink jet image; d) allowing the composite to cool; and e) peeling the flexible, polymeric support of the transfer laminating element from the composite to form the laminated ink jet print.
摘要:
An ink jet printing process comprising the steps of; a) providing an ink jet printer in which a continuous stream of ink jet ink is emitted from a nozzle that is responsive to digital data signals; b) loading the printer with an ink jet recording element; c) loading the printer with an aqueous inkjet ink comprising water, a dye, a humectant, an organic solvent and a deflection-enhancing additive comprising a diethanolamine or 1-amino-2-propanol; and d) ejecting ink from a thermally-steered continuous ink jet print head onto one of the ink jet recording elements in response to the digital data signals.
摘要:
The invention relates to an imaging member comprising at least one image layer and a base, said base comprising a cellulose paper that has its surfaces impregnated with water dispersible ester-based condensation polymer wherein the surface of said base has a roughness of less than 2.03 &mgr;m Ra and a hydrophobicity as measured by 40/20 Acid Valley test in excess of 500 seconds.
摘要:
A method for producing an image, the method comprises the steps of: storing a plurality of theme images; storing a plurality of annotations; providing a random number generator for randomly selecting the theme images and annotations; and combining the theme image and the annotation.
摘要:
Apparatus for forming an image on a receiver in response to a digital image includes print heads for transferring colorant to the receiver. The receivers are stored in a receiver supply device in a humidity controlled environment. A receiver transport mechanism moves the receiver to a position where the print heads transfer colorant to the receiver to form an image on the receiver.
摘要:
An ink jet printing process for improving the light stability of an ink jet image comprising: providing an ink jet recording element comprising a support having thereon an image-recording layer comprising a cross-linkable polymer of gelatin or acetoacetylated poly(vinyl alcohol) and a mordant; applying liquid ink droplets of a dye on the image-recording layer in an image-wise manner, the dye being a water-soluble deprotonated cationic dye which is capable of being reprotonated to a cationic dye having a N—H group which is part of a conjugated system; and applying an aqueous solution of a multivalent inorganic salt to the image to cross-link the polymer.
摘要:
A method of improving the durability of an ink jet ink image comprising the steps of: a) providing an ink jet ink receiving layer containing acetoacetylated poly(vinylalcohol); b) depositing pigment-based ink jet ink to form an image on the gelatin-containing ink receiving layer; and c) applying to the image formed in step b) a solution comprising a hardener.
