摘要： 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.

摘要： The invention relates to a method for modifying nanofibrillar cellulose composition, comprising—preparing fibrous dispersion of ionically charged nanofibrillar cellulose (NFC), and—applying heat treatment at a temperature of at least 90° C. to the fibrous dispersion until the viscosity of NFC starts to decrease. The viscosity of the heat-treated NFC is reversible by applying shear forces to the NFC.

摘要： 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.

摘要： An image destruct material comprises a release layer positioned between an image receiving layer and a base layer. The adhesion between the release layer and the base layer is greater than adhesion between the release layer and the image receiving layer. The release layer material can be used in secure documents that have an image receiving layer. After information is printed on the image receiving layer, an overlaminate is applied over it. Removal of the overlaminate destroys the printed image on the receiving layer because of the relative adhesive properties of the image receiving layer, overlaminate and release layer.
摘要翻译：图像破坏材料包括位于图像接收层和基底层之间的释放层。脱模层与基层之间的粘附性大于剥离层和图像接受层之间的粘合。释放层材料可用于具有图像接收层的安全文档中。在图像接收层上打印信息之后，在其上施加覆盖层。由于图像接收层，覆盖层和释放层的相对粘合性质，去除层叠体会破坏接收层上的印刷图像。
