The present invention relates to a coated article, comprising a carrier material and a resin composition, preferably a B-stage resin composition. The invention further relates to the method of preparing said coated article and in particular to the use of said coated articles for the manufacture of shuttering boards.

A strength additive system for manufacturing paper, board, tissue or the like includes preferably as separate components, a cationic strength agent, such as a cationic polymer with aldehyde functional groups, and an anionic copolymer obtained by polymerization of a reaction mixture including (meth)acrylamide and anionic monomers, the standard viscosity of the obtained copolymer being in a range of 1.5-5.0 mPas. A method for manufacturing of a paper, board, tissue or the like is further disclosed.

The invention relates to a method for producing a covering layer for elastic laminate comprising a) impregnating a carrier fabric, b) applying a surface coating comprising a crosslinker and a prepolymer that can be crosslinked via reactive end groups, c) crosslinking the crosslinkable prepolymer, and d) drying the elastic laminate covering layer. The papers obtainable in this manner are suitable for producing a laminate that, with the elastic outer face thereof, has a pleasant and appealing feel underfoot and good haptics.

The disclosure describes a process for making a décor paper from a dispersion with improved optical performance by (a) combining a treated TiO.sub.2 particle having a surface area of at least about 30 m.sup.2/g with water and a cationic polymer to form a TiO.sub.2 particle slurry; wherein the treated TiO.sub.2 particle comprises an oxide selected from the group consisting of silicon, aluminum, phosphorus and mixtures thereof; and the oxide is present in the amount of at least 15% based on the total weight of the treated titanium dioxide particle; (b) combining the TiO.sub.2 particle slurry of step (a) with paper pulp and a cationic polymer. The dispersion provides equal optical performance using less TiO.sub.2 when compared to the same dispersion not comprising the TiO.sub.2 particle slurry of (a). These décor papers are useful in preparing paper laminates.
