PROCESS FOR DEPOSITING MULTIPLE FLUID LAYERS ON VARIOUS SUBSTRATES
Provided herein are methods for printing an image on a substrate using various methods of deposition in a single process. The methods may comprise a base layer application step wherein a base layer is applied to a portion of the substrate using a valve jet, or an inkjet printhead and a graphical application step wherein one or more ink layers are applied to a portion of the substrate (e.g., using an inkjet or a valve jet). Advantageously, the base layer may be applied only to substantially the same portion of the substrate as the one or more ink layers. The methods may further comprise a top coating step wherein a topcoat is applied to the printed portion of the substrate using a valve jet or an inkjet printhead.
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.
PATTERN-TRANSFERRED OBJECT MANUFACTURING METHOD
The present invention aims to provide a method of producing a pattern-transferred product with simple steps, the method being capable of producing a pattern-transferred product having good adhesion between a transferred pattern and the transfer-receiving body. The method of producing a pattern-transferred product of the present invention includes a step of forming a transfer pattern on a dissociation layer of a transfer sheet including at least a porous layer on a support and the dissociation layer on the porous layer; a transferring step, the step being selected from a step of transferring the transfer pattern to a transfer-receiving body having an adhesive surface or a step of transferring the transfer pattern to a transfer-receiving body via an adhesive material; and a step of removing adhesion from the surface of the transfer-receiving body or from the adhesive material.
PRINTED OBJECT
Disclosed is a printed object which, even if using a receptive layer that is difficult for a monomer in an active energy ray curable ink to penetrate, has excellent adhesion between the active energy ray curable ink and the receptive layer, and in which the amount of unreacted monomer dissipated from the printed object is low. This printed object includes an ink receptive layer laminated on a substrate surface and having an ink absorption rate of 100% or less, and an ink layer laminated on a surface of the ink receptive layer and made from an active energy ray curable ink which includes a polymerizable compound, wherein the glass transition temperature of the polymerizable compound is 45-25 C.
Inkjet receptive compositions and methods therefor

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.
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.
