PROCESS FOR THE PRODUCTION OF A COATED AND PRESSED CELLULOSIC FIBROUS FLAT SUBSTRATE, SUITABLE COATING COMPOSITIONS, THEIR PRODUCTION, THE COATED AND PRESSED SUBSTRATES AND THEIR USE AS SUBSTRATES FOR GRAPHIC PROCESSES

摘要

The invention provides a process for the production of a coated and pressedcellulosic fibrous flat substrate of loose, optionally bonded fibers, byapplication of (M) an aqueous coating composition, containing a binder (B), awhite pigment (W) and a dispersant (D), wherein at least a part of the whitepigment (W) is (A) a particulate ammonium polyphosphate of crystalline form IIof average particle size 40 µm and with a water solubility 10 g/l at 25~C, to the face of the substrate and subjecting to pressure, in particular forthe production of coated and pressed substrates of outstanding surfaceproperties, particularly suitable for graphic processing, and of outstandingnon-flammability properties, suitable coating compositions, their production,the coated and pressed substrates and their use as substrates for graphicprocesses, especially printing.
