Abstract

The present invention discloses a coating composition for printing, and uses thereof. The composition comprises: microfibrillated cellulose, a plurality of polysaccharide hydrocolloids, and the like. The present invention further relates to uses of the coating composition. The composition has the advantages that problems of hair shedding and powder shedding of printing paper during a printing process can be effectively reduced, commercial values are provided, and production efficiency can be increased.

Description

technical field [0001] The present invention relates to a coating composition for printing. Background technique [0002] Lint is a phenomenon in the soil of fibers, fiber fragments or vessel molecules, which is related to the properties of pulp and paper, as well as printing conditions. Dusting is the result of the loss of fillers or other fine material that is not firmly adhered to the paper surface. At present, the two phenomena are easy to appear during the printing process, causing the printing quality to deteriorate. When it is serious, the printing must be stopped for cleaning. Therefore, there is an urgent need for an improved paper, or said improved composition, which reduces the tendency to lint and dust. Contents of the invention [0003] The invention provides a coating composition for printing. [0004] A coating composition for printing, comprising microfibrillated cellulose and various sugar hydrocolloids, wherein 1-75% by weight is microfibrillated cellu...
