The image receiving layer comprises pigment fillers, polymeric binders and ink optical density enhancement agents. Also disclosed is a method for producing the textured media.
Printing paper
A printing paper having a base paper and an outermost coating layer is provided, and satisfies at least one of the following characteristics (I), (II) and (III): (I) when an aqueous solution having a surface tension of 20 mN/m is dropped on the side having the outermost coating layer of the printing paper, a contact angle between the droplet and the outermost coating layer is 40 or more and 65 or less; (II) for the side having the outermost coating layer of the printing paper, a transfer amount of an aqueous solution having a surface tension of 20 mN/m at a contact time of 1 second as determined by the Bristow method is 5.0 ml/m.sup.2 or more and 12.0 ml/m.sup.2 or less; and (III) on the surface of the outermost coating layer of the printing paper, a maximum peak value of specular reflection light quantity of a point image is 2,000 or more and 30,000 or less.
Laminated article
A flexible inkjet printed article includes an ink receptive medium comprising a substrate and an aqueous-based ink-receptive layer. The aqueous-based ink-receptive layer has: (a) a water-soluble salt of a multivalent metal cation; (b) one or more of a polyvinyl alcohol and a polyvinyl amine (or a copolymer derived from a vinyl alcohol and a vinyl amine) at 0.5-30 weight %; and optionally, (c) a crosslinking agent or (d) silica particles. An inkjet-printed image is disposed on the ink-receptive layer, provided from one or more aqueous pigment-based inks, each having: a) one or more anionically-stabilized pigment colorants; b) one or more water-miscible humectants at 1-20 weight %, each of which has a carbon atom to oxygen atom ratio of at least 1.0:1.0 and only two hydroxy groups. A functional layer comprising an adhesive composition disposed on the inkjet-printed image; and a flexible polymeric film or paper adhered to the functional layer.
Recording media
The present disclosure is drawn to a recording medium including a substrate, a first coating applied to the substrate, and a second coating applied to the first coating. The first coating can include inorganic pigment, fixative agent, and a first binder. The second coating can include inorganic nanoparticles, aluminum silicate, and a second binder.
Solvent resistant glossy printable substrates and their methods of manufacture and use
Printable substrates that provide a glossy printable surface with solvent resistance are provided. The printable substrate may include a base sheet having a first surface and a second surface, and a printable coating on the first surface. The printable coating includes a film-forming binder mixture, a crosslinking agent, a partially hydrolyzed polyvinyl alcohol, a first plurality of first silicon dioxide microparticles, a second plurality of second silicon dioxide microparticles, and a cationic dye fixative. The printable substrate may have a gloss level of about 50 to about 60 based on measurement of a gloss meter set with an angle of measurement of 75 degree on the external surface of the printable coating.
Primer for digital printing
The present invention is directed to primer coatings that enhance the adhesion of liquid digital printing inks and toners to the substrate. The coatings comprise one or more polyurethane dispersions and one or more acrylic emulsions. The coatings of the present invention improve resistance to mineral oils, such as those typically found in liquid digital printing inks and toners. The primer coatings of the invention also reduce blocking, so that a primer coated reel of substrate may be easily unrolled, even after having been stored in the rolled reel for an extended period of time.
AQUEOUS POLYURETHANE RESIN DISPERSION
An aqueous polyurethane resin dispersion includes a cationic group and a polyalkylene oxide in a side chain thereof. The polyurethane resin is obtainable by reacting a polyester polyol, a polyether diol, a polyol containing a quaternary N-atom or tertiary amino group, and a polyisocyanate. The polyester polyol is obtained by reacting an aromatic polycarboxylic acid and a polyol. The polyurethane resin is suitable as a resin in treatment liquids of substrates and images made by inkjet printing.
LEVELING COMPOSITIONS
The present disclosure is drawn to leveling compositions, embossed print media, and methods of preparing embossed print media. The embossed print media can include a media substrate, an image-receiving layer applied to the media substrate at a coating weight of 3 gsm to 50 gsm, and a leveling composition layer. The image-receiving layer can include a pigment filler having an average particle size ranging from 0.1 m to 20 m and a polymeric binder, and in examples herein, is embossed. The leveling composition layer can be applied at a coating weight of 0.2 gsm to 3 gsm to the image-receiving layer, and can include a cationic ionene polymer.
Transfer paper for sublimation printing, comprising a cationic agent
The invention relates to transfer paper for sublimation printing, comprising a fibrous substrate, said transfer paper having one or more cationic agents on at least one face thereof, deposited on the fibrous substrate by means of surface treatment, the amount of cationic agent(s) being greater than or equal to 8% by dry weight of the total dry weight of the compound(s) added to the fibrous substrate by means of the surface treatment.
INKJET RECORDING MEDIUM
An inkjet recording medium, comprising an ink-receiving layer containing an inorganic pigment, a binder, an inkjet ink-fixing agent comprising a cationic compound, and organic spherical particles disposed on at least one surface of a base paper, wherein the ink-receiving layer further contains a water-soluble metal salt and 5 parts by weight or more to 15 parts by weight or less of polyvinyl alcohol (A) with a polymerization degree of 700 or less and 20 parts by weight or more to 40 parts by weight or less of polyvinyl alcohol (B) with a polymerization degree of 1200 or more as the binder with respect to 100 parts by weight of the ink-receiving layer; and a volume 50% average particle diameter (D50) as measured by a laser diffraction/scattering method of the organic spherical particles is 15.0 m or more.
