A binding material to obtain a molded body by binding fibers to each other, includes a thermoplastic resin and a fluorescent whitener, and the fluorescent whitener has a melting point higher than a fusing point of the thermoplastic resin. The melting point of the fluorescent whitener is preferably 200° C. or more. A content of the fluorescent whitener in the binding material is preferably 1.0 percent by mass or less. The binding material preferably further includes a white pigment.

A sheet forming binder includes a first powder and a second powder having a larger volume average particle size than the first powder. The proportion of the first powder is 10.0% by mass or more relative to the total mass of the first powder and the second powder.

The invention relates to a titanium dioxide particle with high opacity and UV-greying resistance comprising two silica coats and at least one alumina coat, to a method for the obtaining the same, and to the use of said particle in a method for obtaining a decorative paper laminate or a décor foil. The present invention further pertains a decorative paper laminate or a décor foil containing said coated titanium dioxide particle.

The invention relates to a wrapper paper for smoking articles, comprising cellulose fibres loaded with calcium carbonate particles, wherein the mass of the cellulose fibres loaded with calcium carbonate particles is at least 1% of the mass of the wrapper paper, and the calcium carbonate particles in the cellulose fibres loaded with calcium carbonate particles make up at least 5% and no more than 80% of the mass of the cellulose fibres loaded with calcium carbonate particles.

The present invention concerns a process for preparing self-binding pigment particles from an aqueous suspension of calcium carbonate containing material, wherein an anionic binder and at least one cationic polymer are mixed with the suspension.

A process for converting natural calcium carbonate into precipitated calcium carbonate, involving treating the natural calcium carbonate with a sulfate to produce a gypsum and reacting the gypsum with at least one carbonate source to produce precipitated calcium carbonate. The crystalline polymorph, particle size, and various other characteristics of the precipitated calcium carbonate are controlled by varying conditions during the reacting. Since the natural calcium carbonate is not calcined, the process relates to a low energy method of producing precipitated calcium carbonate of controlled polymorph and particle size with limestone, marble, or chalk as the calcium source.

The present invention relates to a process for the preparation of precipitated calcium carbonate allowing for a more sustainable and cost-efficient use of milk of lime. The obtainable products show good optical properties as well as fine particle size distributions.

Discloses is a packaging paper for food having a grammage between 20 g/m.sup.2 and 40 g/m.sup.2, and having a filler content of less than 20 wt. % relative to the weight of the uncoated paper. On at least one side the packaging paper has a coating that contains a vegetable oil encapsulated in a polymer, and also talc and a binder. Both sides of the finished packaging paper have a Cobb 60 value of 14 g/m.sup.2 to 22 g/m.sup.2.

The present invention refers to a mineral matter powder preparation by wet process without acrylic additive or other grinding aid additives and to Me use of said mineral matter after an optional hydrophobic treatment. Said mineral material Having superior dispersing properties.

The present invention concerns a process for the preparation of flocculated filler particles, wherein at least two aqueous suspensions of at least one filler material and at least one flocculating additive are combined.
