The invention relates to an aqueous polymer dispersion and its preparation. The dispersion comprises a styrene acrylate polymer, which is obtainable by free-radical polymerisation of 1-90 weight-% of monomer (a), which comprises at least one optionally substituted styrene; 10-99 weight-% of monomer (b), which comprises at least one alkyl (meth)acrylate, and 0-9 weight-% of monomer (c), which comprises at least one ethylenically unsaturated monomer, which is different from monomer (b). The polymerisation is conducted in a polymerisation medium comprising a cationic prepolymer, which is obtainable by free radical polymerisation of at least 10-55 weight-% of a monomer (i), which comprises at least one ethylenically unsaturated quaternary and/or tertiary amine, 35-90 weight-% of a monomer (ii), which comprises at least one optionally substituted styrene, and 0-55 weight-% of a monomer (iii), which comprises at least one alkyl (meth)acrylate. The oligomer content in the polymer dispersion is ≤1.4 weight-%, calculated from the dry polymer content.

Prepreg obtained from a decor base paper impregnated with a formaldehyde-free impregnating resin solution, whereby a hydrophobic coating is applied onto at least one side of the prepreg, and decorative film or decorative coating material containing the prepreg according to the invention.

The present invention relates to a water-, oil- and grease-resistant multilayer coating for a paper-based substrate comprising a water-based inner primer coating, an intermediate polymeric extrusion coating, and a water-based top barrier coating, wherein a surface of the paper-based substrate coated therewith has water, oil and grease barrier properties, and wherein the paper-based substrate coated therewith is repulpable and recyclable.

Provided are tissue products comprising a single ply tissue web that has been prepared by a creping process and more preferably by a print creping process adapted to dispose a non-crosslinked latex polymer on at least one of the outer surfaces of the tissue web. The creped single ply tissue products generally have a low degree of stiffness, such as a Stiffness Index less than about 8.00, and are highly durable, such as a Durability Index greater than about 12.0. In other instances, the tissue products may have very low levels of lint or dust, such as a Slough less than about 4.00 mg, even at basis weights from about 45 to about 55 grams per square meter (gsm) and tensile strengths from 600 to 1,200 g/3″.

A coating agent for paper comprises: an ethylene-vinyl alcohol copolymer, wherein the ethylene-vinyl alcohol copolymer has a content of ethylene units of 1 mol % or more and less than 20 mol % and a block character of the ethylene units from 0.90 to 0.99. Coated paper is obtained by coating paper with such a coating agent. The coating agent of the present invention is excellent in viscosity stability and also causes the resulting coated paper to be excellent in barrier properties and water resistance.

Disclosed are multi-ply tissue products, particularly creped and through-air dried tissue products, having cloth like properties, such as good drapability and durability. For example, the products generally comprise two plies and have a geometric mean slope (GM Slope) less than about 10.0 kg and a geometric mean tensile energy absorption (GM TEA) of about 15 g.Math.cm/cm.sup.2 or greater. In certain instances, the tissue products also have a low degree of stiffness, such as a Stiffness Index less than about 5.00. The tissue products may be prepared from webs manufactured by a print-crepe process that deposits a latex polymer on at least one of the outer surfaces of the tissue web.

There is provided a resin-impregnated decorative paper (2) formed by impregnating a decorative paper (4) with an impregnating resin (5). The decorative paper (4) includes: a base paper (6); a picture pattern layer (7) provided on a surface (6a) side of the base paper (6); a filling layer (8) provided on a surface (7a) of the picture pattern layer (7); and a foamed resin layer (9) provided on a surface (8a) of the filling layer (8). The filling layer (8) contains at least one of an epoxy-based resin, an acrylic-based resin, a urethane-based resin, and a casein-based resin.

Release paper base paper includes a substrate; and a coating agent containing a modified polyvinyl alcohol (A) and sodium acetate, the substrate coated with the coating agent, wherein the modified polyvinyl alcohol (A) has 0.005 mol % or more and less than 10 mol % of double bonds derived from unsaturated carboxylic acid or a derivative thereof (B) in side chains, has 1.4 mol % or more and 2.0 mol % or less of 1,2-glycol bond, units, and is water soluble, and a content of the sodium acetate relative to the modified polyvinyl alcohol (A) is 0.01 mass % or more and 10 mass % or less. The release paper base paper of the present invention is excellent in sealing properties for silicone. Use of the release paper base paper allows acceleration of curing of silicone in a release layer and improvement in adhesion between the substrate and the release layer.
