  • Publication number: 20120107533
    Abstract: A method for the preparation of a coated substrate is provided, comprising the steps of providing a substrate; applying on at least one side of said substrate a first coating layer of a first aqueous composition comprising porous anionic pigment particles having a BET surface area of above 40 m2/g and a binder and applying on said first coating layer, a second coating layer of a second, aqueous composition comprising cationic colloidal silica or silicate based particles and polyalkylene glycol. It has been found that a substrate coated with the combination of the first coating layer and the second coating layer provides a suitable substrate for high-quality and fast-drying inkjet printouts.

  • Patent number: 8119201
    Abstract: The invention relates to a painting tool and method of use for manipulating painting material on a painting surface. The method includes providing the tool, which includes a handle and blade. The blade is made of a resilient metal, has a matted surface, and includes handle, middle and distal sections. The handle section has a first end positioned within the middle third of the handle and a second end connected to the middle section. The middle section connects at a first end to the handle section and at a second end to the distal section. The distal section extends from the middle section and is in a distal section plane offset from the handle section. The distal section plane is at an angle to the handle section plane. The distal section is used to take a painting material and place and manipulate the painting material onto a painting surface.

    Abstract: Provided is an aqueous ink with high storage stability and scratch resistance at such a high level that the coloring material of an image is not scraped off even when lightly touched with a sharp product. The aqueous ink includes a water-insoluble coloring material and plural polymers. The plural polymers include a polymer A which relatively contributes to dispersion of the water-insoluble coloring material and a polymer B which does not relatively contribute to the dispersion of the water-insoluble coloring material compared to the polymer A. The polymer A includes a block copolymer having an acid value of 120 mgKOH/g to 180 mgKOH/g and having an ethylene oxide group as a nonionic group. The polymer B has an acid value of 150 mgKOH/g or less and a hydrogen bond parameter (?h) of the polymer obtained by solubility parameters of monomers constituting the polymer of 1.0 cal0.5/cm1.5 or more and 3.2 cal0.5/cm1.5 or less.
