摘要:
A surface-treatment agent containing at least one type of processed starch selected from a) to c) as listed below is applied to a base paper of a newspaper so that a product of a B-type viscosity of the surface-treatment agent, measured under conditions of 10% concentration at 50° C. (rotor No. 1 at 60 rpm), and an application amount of the surface-treatment agent (both sides) is within a range of 2 to 15 cps·g/m2; a) Etherified starch, which is etherified by the compound defined in the general formula (1) given below: (AO)nH (1) wherein A represents an ethylene group or propylene group, while n represents an integer of 1 to 15, b) Carboxylic acid esterified starch, which is esterified by monocarboxylic acid or dicarboxylic acid containing a linear, branched or cyclic alkyl group or alkenyl group having carbon atoms of 4 to 18, and c) Aldehyde starch.
摘要:
Provide a paper offering good paper strength properties in terms of strength and stiffness, high smoothness and excellent printing quality by adjusting the ash content in paper to a range of 3 to 40 percent by solid weight and allowing the paper to contain a pre-coagulated filler having an average particle size of 10 to 80 μm as measured by the laser diffraction method, wherein such filler is obtained by processing a filler using a composite acrylamide copolymer comprising (A) an anionic polysaccharide and (B) a cationic and/or amphoteric acrylamide copolymer.
摘要:
Produce a slipping property imparting agent for clear coat that reduces scum production: wherein, (1) the agent comprises a copolymer whose constituents are unsaturated olefin (constituent (a)) and unsaturated carboxylic acid (carboxylate) (constituent (b)); (2) constituent (a) accounts for 50 to 99 mol percent and constituent (b) accounts for 50 to 1 mol percent, respectively, of the total mol number of constituents (a) and (b) combined; and (3) a constituent (c) that can be polymerized with the constituents (a) and (b) is contained, as necessary, by up to 20 mol percent of the total mol number of constituents (a) and (b) combined.
