    Abstract: A composition comprising nanocellulose is disclosed, wherein the nanocellulose contains very low or essentially no sulfur content. The nanocellulose may be in the form of cellulose nanocrystals, cellulose nanofibrils, or both. The nanocellulose is characterized by a crystallinity of at least 80%, an onset of thermal decomposition of 300° F. or higher, and a low light transmittance over the range 400-700 nm. Other variations provide a composition comprising lignin-coated hydrophobic nanocellulose, wherein the nanocellulose contains very low or essentially no sulfur content. Some variations provide a composition comprising nanocellulose, wherein the nanocellulose contains about 0.1 wt % equivalent sulfur content, or less, as SO4 groups chemically or physically bound to the nanocellulose. In some embodiments, the nanocellulose contains essentially no hydrogen atoms (apart from hydrogen structurally contained in nanocellulose itself) bound to the nanocellulose. Various compositions, materials, and products may incorporate the nanocellulose compositions disclosed herein.

    Abstract: The invention provides an aqueous painting material composition. which provides a coating film such that, after it has dried, it neither runs nor dissolves in water even if waterdrops adhere thereto, and such that it has water resistance in such a degree that, even if an extra layer of a second aqueous painting material composition is added thereon, it is not shifted, like the conventionally known emulsion paints, and further such that, even if it has adhered to a palette or a paintbrush, and dried, it can be readily washed away by washing it with water.The aqueous painting material composition comprises water, a coloring pigment, a water-soluble resin, and a resin emulsion, wherein the aqueous painting material composition contains a hydroxyalkyl cellulose only as the water-soluble resin, and the resin emulsion in an amount of 0.1% by weight or more and less than 5% by weigh in a solid basis.
