The present invention is related to a deinking primer composition for deinking of a substrate, wherein said deinking primer composition comprises a binder component that has a polymeric backbone with pendent hydroxy or carboxy groups that have been esterified or acetalised or ketalised to such an extent that the binder component has an acid value of 0-50 mg KOH/g or a hydroxyl value of 0-600 mg KOH/g, preferably 0-400 mg KOH/g, so that a primer layer prepared from said deinking primer composition is dissolvable in an alkaline aqueous medium.

A process including providing a paper substrate; disposing a water soluble precoat composition onto all or a portion of the paper substrate to provide a treated paper; applying an image onto the treated paper using a toner or an aqueous ink to provide an imaged paper; wherein the water soluble precoat composition forms a temporary barrier between the toner or aqueous ink and the paper substrate; and wherein, during a paper pulping process, the water soluble precoat composition dissolves thereby releasing the toner or aqueous ink from the paper substrate.

Ink compositions and methods of use for reliably printing on alkaline and readily oxidizing surfaces comprise one or more water-soluble polymeric dyes, one or more solvents for adjusting viscosity, surface tension, and/or heat tolerance, and water, the dyes being “loaded” in the ink sufficiently to meet the relevant color and optical density requirements for the ink while such ink composition still also meets the duty cycle requirements of the application.

Eco-friendly signs such as wood and other natural material signs, and methods of making eco-friendly signs, including selecting a substrate as a base material having a first planar surface and an opposing second planar surface, cutting the substrate to a sign dimension, treating the first planar surface to form a smooth print surface, applying a base layer such as a layer of clear ink to the print surface, and applying a signage layer onto the base layer. The eco-friendly sign may be an ADA compliant sign in which the signage layer is a raised of ink produced using a 3-dimensional printer.

Provided is an image recording method including a step of preparing an ink containing water and a white pigment, and a step of jetting the ink from an ink jet head in a liquid droplet amount of 1.0 pL or greater to apply the ink onto a base material, in which in a case where an ink jetting surface of the ink jet head is immersed in the ink in a vertically standing state for 2 seconds, the jetting surface is pulled up from the ink in the state, and the jetting surface is allowed to stand in the state for 1 minute, a ratio of an area of a region to which the ink is adhered to an area of the jetting surface is 40% by area or less.

The disclosure relates to ink compositions for digital printing on an external surface of a plastic article. The ink compositions comprise an ink removal-promoting additive. In some aspects, the ink removal-promoting additive can facilitate the separation or loosening of the image from the external surface of the article when the image is exposed to a liquid-based solution at an elevated temperature. Also disclosed are recyclable plastic articles having an external surface with an image printed thereon using the disclosed ink composition and methods for removing cured ink from a plastic container. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

A dye printing treatment liquid composition to be adhered to a cloth, includes: a polyester resin having a glass transition temperature of 40° C. or more; a cross-linking agent; and water, and the cloth contains fibers which have hydroxy groups.

A multi-layered composite comprising a substrate and a conductive film is provided. The substrate contains a polymer composition that contains a thermoplastic polymer having a deflection temperature under load of about 40° C. or more as determined in accordance with ISO 75-2:2013 at a load of 1.8 MPa. The conductive film contains a noble metal. The composite exhibits an electromagnetic interference shielding effectiveness of about 25 decibels or more as determined in accordance with ASTM D4935-18 at a frequency of 10 GHz and thickness of 3 millimeters.

The ink jet recording method includes ejecting an aqueous ink from a recording head to apply the aqueous ink to a recording medium, to thereby record an image. The ink jet recording method includes: ejecting the aqueous ink heated to a temperature T.sub.H (° C.) from the recording head to apply the aqueous ink to the recording medium; and heating the recording medium having the aqueous ink applied thereto to a temperature T.sub.F (° C.), the aqueous ink containing a pigment and a polyester resin particle, a glass transition temperature T.sub.G (° C.) of the polyester resin particle, the temperature T.sub.H (° C.) and the temperature T.sub.F (° C.) satisfying relationships of the following expressions (1) to (3).

T.sub.G(° C.)>T.sub.H(° C.)   (1)

T.sub.F(° C.)≥T.sub.H(° C.)+10° C.   (2)

T.sub.F(° C.)≥T.sub.G(° C.)−10° C.   (3)
