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.
PRETREATMENT LIQUID, INK SET, IMAGE RECORDED MATERIAL, BASE MATERIAL FOR IMAGE RECORDING, METHOD OF PRODUCING BASE MATERIAL FOR IMAGE RECORDING, AND IMAGE RECORDING METHOD
Provided are a pretreatment liquid for recording an image on an impermeable base material with an aqueous ink, the pretreatment liquid including an aqueous medium, a resin a having a glass transition temperature of lower than 25 C., and particles of a resin b having a glass transition temperature of 25 C. or higher; an ink set; a base material for image recording; an image recorded material; a method of producing a base material for image recording; and an image recording method.
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.
METHOD OF PRODUCING RECORDING MEDIUM AND IMAGE RECORDING METHOD
Provided are a method of producing a recording medium, including a step of preparing a liquid A which includes at least one kind of aggregating agent selected from the group consisting of an acid, a polyvalent metal compound, and a metal complex, and water, a step of preparing a liquid B which includes a resin and water, a step of mixing the liquid A with the liquid B at an ambient temperature of 5 C. to 40 C. to obtain a mixed solution, a step of storing the mixed solution at an ambient temperature of 5 C. to 40 C., and a step of applying the mixed solution after the storage onto an impermeable base material within 30 days from the start of mixing the liquid A with the liquid B to obtain a recording medium; and an image recording method.
INKJET RECORDING MEDIUM
An inkjet recording medium includes a substrate having a resin layer, a bonding layer disposed on the resin layer, and an ink-receiving layer disposed on the bonding layer. The surface of the inkjet recording medium on the ink-receiving layer side of the inkjet recording medium has a 20 glossiness of 13.0 or more. The bonding layer contains an ultraviolet inhibitor at a content of 5.0% by mass or more and 35.0% by mass or less based on the total mass of the bonding layer.
Inkjet printing
The present disclosure relates to an inkjet printing process that comprises inkjet printing an inkjet ink composition onto a substrate to form a printed inkjet ink layer. The inkjet ink composition comprises a colorant, a curable polyurethane dispersion, a photoinitiator and water, wherein the amount of curable polyurethane dispersed in the inkjet ink composition is 0.1 to 30 weight %. A radiation-curable overcoat composition is inkjet printed over the printed inkjet ink layer as an overcoat layer. The overcoat composition comprises a curable polyurethane dispersion, a photoinitiator and water, wherein the amount of curable polyurethane dispersed in the overcoat composition is 0.1 to 30 weight %. The printed inkjet ink layer is cured by exposing both the printed inkjet ink layer and the overcoat layer on the substrate to radiation.
FABRIC PRINTABLE MEDIUM
A fabric printable medium includes a fabric base substrate having an image-side and a back-side. The fabric printable medium also includes a flame retardant ink receiving layer on the image-side of the fabric base substrate.
