Print quality on thin coatings of cellulose nanocrystals
The present invention relates to the use of cellulose nanocrystals (CNC) blended with a polymeric material selected from a polyvinyl alcohol) (PVOH), an ethylene acrylic acid copolymer (EAA), other carboxylated polymer latexes, or other polymer blends, and applied as a thin coating layer on plastic films for printing with digital processes such as inkjet and laser printing, as well as with more conventional printing processes such as flexography and offset lithography, to the control of ink adhesion to the plastic film, and to the reduction in the oxygen transmission rate (OTR) of the plastic film.
Inkjet recording method and inkjet recording medium

Manufacturing of decorative laminates by inkjet
A method of manufacturing decorative laminates includes the steps of a) inkjet printing a first decorative layer by a first multi-pass inkjet printer and delivering the inkjet printed first decorative layer to a laminate heating press where it is heat pressed into a decorative laminate; and b) inkjet printing a second decorative layer by a second multi-pass inkjet printer and delivering the inkjet printed second decorative layer to the same laminate heating press where it is heat pressed into a decorative laminate.
IMPROVED TRANSFER PAPER FOR INKJET PRINTING
The invention is directed to a transfer paper suitable for high speed inkjet printing comprising a base layer and a film layer suitable for receiving viscous ink and releasing disperse dye from said viscous ink by having a porosity of 100 to 500 ml/min, wherein the film comprises film forming material.
Coated print medium
The present disclosure is drawn to a coated print medium, a method of preparing a print medium, and a printing system. The coated print medium can comprise a substrate and a coating applied to the substrate. The coating can comprise, by solids or dry weight, 5 wt % to 30 wt % of a polymeric binder, 20 wt % to 50 wt % of a cationic latex, 5 wt % to 15 wt % of a multivalent cationic salt, and 1 wt % to 20 wt % of a sulfonic acid- or sulfonate-containing stilbene optical brightener.
RECORDED MATTER
The transfer material has a laminated structure in which a base material sheet, a transparent sheet, and a coloring material-receiving layer are laminated in the stated order, in which: the coloring material-receiving layer contains inorganic fine particles and a water-soluble resin; the transparent sheet contains at least two kinds of emulsions including an emulsion E1 and an emulsion E2; and the emulsion E1 has a glass transition temperature Tg1 of more than 50 C. and less than 90 C., the emulsion E2 has a glass transition temperature Tg2 of 90 C. or more and 120 C. or less, and at least the emulsion E2 remains in a particle state in the transparent sheet.
