摘要:
A manufacturing an ink-receiving medium comprising the steps of providing a support, treating the support with a salt of a multivalent metal cation, and coating upon one or each side of the support at least one porous ink-receiving top layer from an aqueous coating composition consisting of non-cationic components, wherein the non-cationic components comprise a binder and anionic particles of average particle size less than 2.5 microns, wherein the ink-receiving top layer comprises at least 50% of the total solids by weight, such that the water-soluble salt of a multivalent metal cation is able to diffuse into the ink-receiving top layer, the method further comprising drying the coating and optionally calendering the coating. Also disclosed is inkjet media made from such method and a method of printing using such inkjet media.
摘要:
A bleachable composition, including an acid photogenerator and a near-infrared radiation-absorbing dye or pigment, is utilized in a method of migration imaging to prevent unwanted absorptions. This composition can be incorporated either in the thermoplastic imaging surface layer of the imaging element, in the marking particles applied to the element, or both. Alternatively, the components of the bleachable composition can be separated with one in the thermoplastic imaging surface layer and the other in the marking particles. After the imaging element is marked and exposed with near-infrared radiation, the bleachable composition caused exposed portions of the imaging element to be bleached. If further bleaching is needed, the element can subsequently be exposed with near-ultraviolet radiation. A migration imaging method, which does not employ the bleachable composition of the present invention, wherein marking particles are magnetically attracted to the imaging element, is also provided.

摘要:
A receiver material, especially a receiver sheet, for electrophotographic thermoplastic toner particles provides toner images of photographic quality and high gloss in both the toned and untoned areas of the sheet. The paper support of the receiver material is protected against moisture damage by a thermoplastic hold-out layer on which is formed a thermoplastic toner receiving layer that is adhesively compatible with the toner and with the hold-out layer. The receiver material, including support, hold-out layer and toner receiving layer, has a volume resistivity of 1.0×108 to 1.0×1013 ohm-cm and can be electrostatically charged by back-side charging to receive toner by electrostatic transfer.
摘要:
A process for making an ink jet ink comprising: a) providing an organic pigment dispersion containing a pigment and a carrier; b) mixing the pigment dispersion with rigid milling media having an average size less than about 100 &mgr;m; c) introducing the mixture from step b) into a high speed mill; d) milling the mixture from step c) until a pigment particle size distribution is obtained wherein about 50% by weight of the pigment particles have a particle size less than about 100 nanometers; e) separating the milling media from the mixture milled in step d); and f) diluting the mixture from step d) to obtain the ink jet ink; wherein the milling media comprises negatively-charged polymeric beads which are crosslinked sufficiently to prevent swelling of the polymeric beads to levels greater than or equal to about 50 volume % within 4 hours at 25° C. in the carrier.
