A coated polymer film, such as a coated polyester film, is disclosed. In one embodiment, the coated film may be used as a substrate for digital printing. In one embodiment, the coating contains an anionic anti-static agent comprising a sulphonated copolyester resin. In an alternative embodiment, the coating contains an anti-static agent comprising an organometallic, such as an organo zirconate, in combination with metal oxide particles. The metal oxide particles may comprise nanoparticles. In one embodiment, the coating can further contain a print enhancing agent and an adhesion promoter.

A friction material which comprises a fibrous base, a binder, a lubricating material, an organic filler, and an inorganic filler, the friction material having a copper element content of 0.5 wt % or less with respect to the whole friction material, wherein the lubricating material comprises graphite having an average particle diameter of 10.0 μm or smaller and the inorganic filler includes barium sulfate, which comprises small-diameter barium sulfate having an average particle diameter of 1.5 μm or smaller and a purity of 95.0% or higher.

Coating compositions are disclosed that include corrosion resisting particles such that the coating composition can exhibit corrosion resistance properties. Also disclosed are substrates at least partially coated with a coating deposited from such a composition and multi-component composite coatings, wherein at least one coating later is deposited from such a coating composition. Methods and apparatus for making ultrafine solid particles are also disclosed.

A non-transparent paper is described for non-transparent art or graphic design sketches, which prevents seepage of the inks, it accepts any type of gel, water-based, solvent-based, oil-based or mixed inks and solid materials for sketching and drawing, as well as fixatives for the solid materials. This paper consists of a lamination of at least two sheets of uncoated bond paper, inserting at least one intermediate layer of pigmented opacifying emulsion between both sheets, applied between the layers of paper to prevent transparency and the seepage of inks from one face of the lamination to the other. This layer of emulsion contains at least one opacifying pigment, at least one adhesive, agents to control viscosity and surface tension and other components. The outside layers of paper have a drying capacity which fixes the materials used for the sketching and prevent outlines made on one face passing to the adjacent sheets of paper, and also has a texture suitable for receiving any dry material for drawing or sketching.

A reusable, fiber containing pulp product is described that is highly suited for use in the manufacture of paper products. The reusable, fiber containing pulp product provides a mixture of fibers and small, dense polymer/particle fragments. The polymer/particle fragments within the reusable, fiber containing pulp product have a size range and density that facilitates efficient removal of the polymer/particle fragments using pressure screens.

Coating compositions are disclosed that include corrosion resisting particles such that the coating composition can exhibit corrosion resistance properties. Also disclosed are substrates at least partially coated with a coating deposited from such a composition and multi-component composite coatings, wherein at least one coating later is deposited from such a coating composition. Methods and apparatus for making ultrafine solid particles are also disclosed.
