The present invention relates to compositions, such as filled and coated papers, comprising microfibrillated cellulose and inorganic particulate material.

Provided is a CM-modified microfibrillated cellulose fiber having a Canada standard freeness of not less than 200 mL and an average fiber diameter of not less than 500 nm. Said fiber enhances paper strength when added to a paper.

It is an object of the present invention to provide a thickener capable of exhibiting excellent light resistance. The present invention relates to a thickener comprising cellulose fibers having a fiber width of 8 nm or less and water, wherein the thickener is a slurry or a gel, and when the thickener is filled in a colorless and transparent glass cell having an inside dimension of 1 cm in depth×4 cm in width×4.5 cm in height and the thickener is then irradiated with ultraviolet rays with a wavelength of 300 nm or more and 400 nm or less, using a xenon lamp, from the side of the maximum area surface of the glass cell, so as to be an irradiance of 180 W/m.sup.2 and an integrated light amount of 500 mJ/m.sup.2, the amount of a change in the yellowness before and after ultraviolet irradiation measured in accordance with JIS K 7373 is 10 or less.

A fibrillated blend of lyocell and cellulosic pulp having a degree of polymerization of 200 to 1000 as measured by ASTM Test 1795-96, a method of making the blend and materials which incorporate the blend.

Provided is an oxidized microfibrillated cellulose fiber having a Canada standard freeness of not less than 200 mL and an average fiber diameter of not less than 500 nm. Said fiber enhances paper strength when added to a paper.

The invention relates to a method for preparing aqueous furnish to be used in paper product manufacturing. In the method aqueous furnish is prepared by making a fiber suspension, and cationic natural polymer (S), alum (A) and anionic nanofibrillar cellulose (F) are added to the aqueous furnish in a short circulation of a paper or board machine.
