A printing process is disclosed which comprises directing droplets of an ink onto an intermediate transfer member to form an ink image, the ink including an organic polymeric resin and a coloring agent in an aqueous carrier, and the transfer member having a hydrophobic outer surface so that each ink droplet in the ink image spreads on impinging upon the intermediate transfer member to form an ink film. The ink is dried while the ink image is being transported by the intermediate transfer member by evaporating the aqueous carrier from the ink image to leave a residue film of resin and coloring agent. The residue film is then transferred to a substrate. The chemical compositions of the ink and of the surface of the intermediate transfer member are selected such that attractive intermolecular forces between molecules in the outer skin of each droplet and on the surface of the intermediate transfer member counteract the tendency of the ink film produced by each droplet to bead under the action of the surface tension of the aqueous carrier, without causing each droplet to spread by wetting the surface of the intermediate transfer member.

Digital printing process

There is disclosed a condensation curable coating composition in the form of an oil-in-oil emulsion, the coating composition being able to protect surfaces coated therewith from undesired contamination by materials coming in contact therewith. The surfaces to be so protected by the coating composition, once cured, can, by way of illustration, be of parts of printing systems and the materials coming in contact with such surfaces can be ink images or residues thereof.

Compositions and protective coatings made therefrom

Disclosed are curable polymer compositions, elastomers thereof and release layers useful in the art of printing made of the disclosed elastomers. Disclosed are also intermediate transfer members having a release layer useful in the art of printing. Disclosed are anisotropic intermediate transfer members. Disclosed are curable adhesive compositions, that in some embodiments are useful in preparing intermediate transfer members useful in printing. Also disclosed are intermediate transfer members useful in the art of printing having a release layer with an image transfer surface having protonatable functional groups apparent thereupon. Also disclosed are methods of making such intermediate transfer members.

Intermediate transfer members for use with indirect printing systems and protonatable intermediate transfer members for use with indirect printing systems

There is disclosed a method of coating mammalian hair, the method comprising applying, on the external surface of individual hairs of the mammalian hair, an oil-in-water emulsion comprising: (i) an aqueous phase containing water; and (ii) an oil phase containing at least one water-insoluble reactive condensation-curable film-forming amino-silicone pre-polymer that, subsequent to condensation curing, forms an elastomer. The reactive oil phase may further contain a plurality of sub-micronic pigment particles dispersed therein. Suitable compositions and kits including the same are also disclosed, as well as methods for preparing the compositions.

Composition, kit and method for coloring keratinous fibers

There is disclosed a method of producing a coating on an external surface of individual mammalian hair fibers, the method comprising (a) applying on the external surface of the individual fibers, an oil-in-water emulsion including an amino-silicone film forming pre-polymer, so as to form an at least partially cured amino-silicone film; and (b) applying an aqueous dispersion on said amino-silicone film, to produce an overlying, optionally pigmented, polymeric film that coats said at least partially cured amino-silicone film; wherein the aqueous dispersion contains: (i) a polymeric material having neutralized acid moieties; and optionally (ii) a plurality of pigment particles, at least partially enveloped by the polymeric material, and dispersed within said aqueous dispersion. Suitable coating or coloring compositions and kits including the same are also disclosed, as well as methods for preparing the compositions or removing films formed therewith.

Compositions, kits and methods for coloring fibers

A printing system and method are provided. The printing system includes an image forming station for temporarily deposit an image on an intermediate transfer member when the intermediate transfer member in the image forming station is in a first temperature range. The system further includes a drying station configured to increase a temperature of the intermediate transfer member from a first temperature in the first temperature range to a second temperature in a second temperature range, the second temperature being substantially higher than the first temperature. The system further includes an impression station configured to transfer the temporarily deposited image from the intermediate transfer member onto a substrate when the intermediate transfer member in the impression station is in the second temperature range. The system further includes a cooling station for retaining a coolant configured to revert the intermediate transfer member to a temperature in the first temperature.

A printing system is disclosed which includes a plurality of rollers configured to support and move a loop-shaped, flexible intermediate transfer member of at least 10 meters in length along a printing system path. The printing system further includes an image forming station configured to form an image on a portion of the intermediate transfer member, and an impression station configured to enable substantial transfer of the deposited image to a substrate. The printing system also includes at least one high-speed motor associated with the plurality of rollers and configured to move the loop-shaped flexible intermediate transfer member at a speed of at least about one meter per second. Moreover, the printing system includes guiding channels configured for exerting a lateral tensioning force on the loop-shaped intermediate transfer member as it is received within the guiding channels and circulates at the speed of at least about one meter per second.

Briefly described, embodiments of this disclosure includes intermediate transfer members, primer layer materials, methods of forming an intermediate transfer member layers having a base and an acrylic rubber layer, are disclosed.
