摘要:
The present invention relates to a dye-donor element for thermal dye transfer comprising a support having on one side a dye layer and on a second side a slipping layer, wherein the slipping layer comprises a first wax comprising a polymer derived from a polyolefin and an ethylenically unsaturated carboxylic acid or ester or anhydride thereof, and at least one other wax and wherein the dye layer comprises at least a magenta dye of Structure I, wherein the dye donor element has reduced 2X retransfer. The present invention also relates to the same slip layer with a dye layer comprising at least a yellow dye of Structure X, or Structure XI, or Structure XII, or Structure XIII, or wherein the dye layer comprises at least a cyan dye of Structure XX.

The invention concerns dye preparations containing, in each case relative to the weight of the preparation, between 0.1 and 30 wt % of one or a plurality of dyes selected from the class comprising anthraquinones or quinophthalones which are free from ionic groups, between 0.1 and 20 wt % of a dispersant based on an arylsulphonic acid - formaldehyde condensation product, and optionally water. The invention further concerns the use of these dye preparations as inks in the ink-jet process and for sublimation transfer printing.

The invention provides a process for forming an acetoacetarylide slurry, comprising: (a) adding a solid acetoacetarylide to a homogenizer; (b) homogenizing the acetoacetarylide in the presence of water and one or more additives to form an acetoacetarylide slurry. The invention further provides a process for forming an acetoacetarylide-based pigment, comprising: (a) reacting a diketene with an amine to form an acetoacetarylide slurry; (b) separating the acetoacetarylide as a solid from the acetoacetarylide slurry; (c) adding the acetoacetarylide solid to a homogenizer; (d) homogenizing the acetoacetarylide in the presence of water and one or more additives to form an acetoacetarylide slurry; (e) pumping the acetoacetarylide slurry to a reaction tank; (f) adding an alkali or alkaline earth metal base to the slurry; (g) adding an acid to form a precipitate of the acetoacetarylide; and (h) reacting the precipitate with a diazonium salt, thereby forming an azo pigment. This invention also includes the pigments and intermediates thereto formed by the above processes.
摘要:
There is provided a thermal transfer sheet comprising a support and, provided thereon, at least a yellow dye-holding layer, a magenta dye-holding layer, and a cyan dye-holding layer, the dye-holding layers each comprising a thermal transfer dye and a binder resin, the yellow dye-holding layer comprising as the thermal transfer dye a dye represented by the following formula 1 and/or a dye represented by the following formula 2, the magenta dye-holding layer comprising as the thermal transfer dye a dye represented by the following formula 3 and at least one dye selected from those represented by the following formulae 4 and 5, the cyan dye-holding layer comprising as the thermal transfer dye a dye represented by the following formula 6:
There is yet further provided a thermal transfer image-receiving sheet for use in the method of claim 1, comprising a substrate sheet, a dye-receptive layer, and, provided between the substrate sheet and the dye-receptive layer, a dye release layer comprising a hydrophilic material.
(a) a dye-donor element comprising a support having thereon a dye layer comprising a dye dispersed in a polymeric binder, the dye having a reactive carbonyl group, and (b) a dye-receiving element comprising a support having thereon a dye image-receiving layer, the dye-receiving element being in a superposed relationship with the dye-donor element so that the dye layer is in contact with the dye image-receiving layer, the dye image-receiving layer comprising a polymer containing a primary or secondary aliphatic amino group.
摘要:
Bei dem vorgeschlagenen Verfahren wird Papierfaserstoff (P), der zumindest teilweise aus bedrucktem Altpapier besteht, mit Wasser (W) suspendiert und sowohl mit Bleich-Hilfsmitteln (CH) als auch Bleich-Chemikalien (OX) vermischt. Die Bleich-Chemikalien (CH) enthalten mit Vorteil molekularen Sauerstoff. Eine intensive mechanische Bearbeitung (2) mit mindestens 20 kWh/to wird vor dem Bleichen (3) vorgenommen, wobei die Bleichdauer mindestens 10 Minuten beträgt und während der Bleiche ein Druck, der über Umgebungsdruck liegt, herrscht. Anschließend wird aus dem gebleichten Stoff der überwiegende Anteil der noch vorhandenen Druckfarbenpartikel entfernt.
