Abstract:
The disclosure relates to a surface treatment composition for inkjet media, including: at least one surface sizing agent selected from the group consisting of starch, starch derivatives, polymeric materials, and combinations thereof; and an ink fixative selected from the group consisting of at least one high valence metallic salt, at least one high valence complex poly-salt, and combinations thereof. The ink fixative is present in the surface treatment composition from about 10 weight % to about 50 weight % of the surface treatment composition. The at least one high valence metallic salt and the at least one high valence complex poly-salt have a valence greater than divalent. In addition, the disclosure relates to a method of making and a system for printing the surface treated media; and an inkjet printable paper.
Abstract:
A film-forming dispersion for the formation of protective coatings on shaped drug and food articles which comprises 1 to 25 weight percent of acetylester of oxidized starch and 0.8 to 8 weight percent of triethylcitrate.
Abstract:
A cellulose fiber-based substrate, at least one side of which is coated with an aqueous mixture composed of: a) at least one water-soluble polymer (WSP) containing hydroxyl groups, b) at least one lactone substituted with at least one linear or branched and/or cyclic C8-C30 hydrocarbon chain which may contain heteroatoms, c) at least one crosslinking agent. A method of production and use thereof.
Abstract:
The invention relates to oxidized starch, to a method of preparing oxidized starch and to the use of the oxidized starch in various applications.
Abstract:
A method of attaching dialdehyde starch to surfaces is disclosed. A substrate to which substances may be coupled, which substrate comprises at least one surface coated with dialdehyde starch, and products produced utilizing the substrate are also provided.
Abstract:
A biodegradable cellulose fiber-based substrate, at least one side of which is coated with a release coating including: a) at least one water-soluble polymer (WSP) containing hydroxyl groups, and b) at least one lactone substituted with at least one linear or branched and/or cyclic C8-C30 hydrocarbon chain which may contain heteroatoms. The biodegradable substrate is certified biodegradable in accordance with EN 13432. A method of production thereof is also disclosed.
Abstract:
The present invention relates to a process for applying optical brightening agent (OBA) to a sheet of paper or paperboard substrate. The process comprises applying the composition comprising a cooked starch and a powdered optical brightener to at least one surface of a paper or paperboard substrate at the size press in a paper or paperboard manufacturing process to form a sized paper or paperboard substrate; and drying the sized paper or paperboard substrate to form a dried sized paper or paperboard substrate.
Abstract:
Reaction products of polymers of vinyl acetate and dialdehyde polysaccharides may be prepared by mixing emulsions of vinyl acetate polymers with aqueous dispersions of dialdehyde polysaccharides at a pH of 4 to 6. The vinyl acetate polymer may be polyvinyl acetate or a copolymer of vinyl acetate with vinyl propionate, vinyl 2-ethylhexoate, vinyl chloride, vinyl maleates, vinyl fumarates, acrylic esters or acrylonitrile, and may be partially hydrolysed, e.g. to contain 2 to 80% of polyvinyl alcohol. A plasticizer, e.g. acetyl triethylcitrate, and protective colloids, e.g. methyl cellulose, sodium carboxymethyl cellulose, hydroxyethyl cellulose, sodium and ammonium polyacrylates, polyvinyl alcohol, alginates and starches, may also be incorporated. The dialdehyde polysaccharide may be prepared by oxidizing starch, cellulose, dextrins and dextrans with periodic acid, and the aqueous dispersion thereof may be prepared by heating a slurry thereof in the presence of a buffer, e.g. sodium acetate, sodium bicarbonate or disodium phosphate. The products are less water-sensitive than the polymers from which they are prepared, and may be used in coating, making films, as binders for non-woven fabrics and in the paper industry.
Abstract:
The invention relates to a substrate intended in use to contact a fouling agent, the substrate including a coating comprising polysaccharide, which coating serves to reduce or prevent fouling of the substrate caused by contact from the fouling agent, in comparison to an equivalent uncoated substrate. The invention also relates to the anti-fouling coating, to apparatus comprising such coating and to related methods of reducing or preventing fouling of a substrate intended in use to contact a fouling agent.
