摘要:
A method of forming a print medium comprising coating at least one side of a base substrate with anionically-charged nano-milled calcium carbonate that has been mixed with a cationic conversion agent to convert the coating to a cationically-charged coating, where a primary size of particles of the nano-milled calcium carbonate is 10-20 nm or smaller.
摘要:
A method for forming a printable coating includes providing a calcium carbonate, combining a dispersant with the calcium carbonate, nanomilling the calcium carbonate and the dispersant to inhibit re-floccing of the nanomilled calcium carbonate, and combining the mixture with a binder at alkaline pH. According to one exemplary embodiment, the coating may be applied to one or more sides of a media substrate.

摘要:
A pattern is provided in coated printed media by flood coating a printed media with an overcoat material that hardens to form an overcoat coating and by controllably removing a portion of the overcoat coating from the printed media in a predetermined region with laser ablation. The printed media in the ablated region remains substantially intact. The ablated predetermined region provides the pattern in the coated printed media.
摘要:
A print medium having a heat-sealable layer supported by an ink receiving layer, the heat-sealable layer having a first component and a second component. The first component and the second component have different particle sizes and different glass transition temperatures. A method of producing the print medium is also disclosed. The print medium is used to produce a photographic-quality image by applying inkjet ink to the print medium. The heat-sealable layer of the print medium is sealed by exposing the layer to a temperature above the glass transition temperatures of the two components. An inkjet printer used to apply inkjet ink to the print medium may include a radiant heater.

A method of producing a print medium to reduce problems associated with the gradual dye-fade and color-shift of inks over time, and to provide improved resistance to physical handling is provided Specifically, a method can comprise steps of coating a media substrate with a porous coating composition of semi-metal oxide or metal oxide particulates to form a porous ink receiving layer, coating the porous ink-receiving layer with a latex layer configured to allow an ink-jet ink to be received at the porous ink-receiving layer, printing ink-jet ink on at least a portion of the latex layer to form ink-associated latex regions exclusive of non-printed latex regions, and heating the latex layer. The ink-jet ink can include an ink vehicle, a colorant, and a film promoting additive that lowers the film forming temperature of the latex particulates in the ink-associated latex regions. Upon heating, the ink-associated latex regions form a continuous film, and non-printed latex regions do not form a continuous film. Associated systems and ink-jet prints are also provided.

A fusible print medium for use in inkjet printing. The fusible print medium includes a substrate and a fusible layer, the fusible layer comprising at least one organic pigment and at least one solid plasticizer. A method of producing the fusible print medium and a method of producing a photographic quality image are also disclosed.
摘要:
The present invention relates to a print medium with improved resistance to airfade. The print medium is coated with a high molecular weight additive having low volatility. The high molecular weight additive is a monomeric or oligomeric compound that has a molecular weight of greater than approximately 1000. The high molecular weight additive is a hindered amine light stabilizer or a fixative. The present invention also relates to a method of producing a print medium with improved airfastness. The method comprises coating a print medium with a high molecular weight additive having low volatility. An image is then printed on the coated print medium and subjected to at least one atmospheric gas. The airfastness of the printed image is measured and compared to the airfastness of an image printed on an uncoated print medium.
摘要:
A process is provided that allows the production of an ink-jet recording media by applying a sealable topcoat to an ink-receptive coating on a substrate. A porous ink-receptive coating comprising a plurality of pores is applied to a surface of the substrate. An anionic porous topcoat comprising polymer particles having a Tg in the range of 60° to 100° C. and a size less than 250 nanometers is applied on the porous ink-receptive coating. The topcoat is then dried at an elevated temperature and an image is printed on the topcoat of the ink-jet recording media using a conventional ink-jet printer. The topcoat is then heated until it becomes fused by using a heating device. The media formed provides the advantages of improved air fade resistance, good image quality and high gloss.
