Composition for coating paper: Composition for coating paper. Nakamura, Masato; Takemura, Shuji; Morimoto, Katsuhiko; Maeda, Hisayoshi (Honshu Paper Mfg. Co., Ltd., Japan). Ger. Offen. DE 2720020 17 Nov 1977, 15 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: D21H001-28. PRIORITY: JP 76-50923 6 May 1976. DOCUMENT TYPE: Patent CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Section cross-reference(s): 42 Compounding epihalohydrin-aliph. amine condensation products with clay dispersions, and binders gave compns. for use in paper coating. Thus, a mixt. of H2O 60, 40% aq. Na polycarboxylate 0.5, clay 100, NaOH 0.1, dimethylamine-epichlorohydrin copolymer [25988-97-0] 1.4, 28% NaOH 1, casein 7, and butadiene-styrene copolymer [9003-55-8] latex 2 parts was applied on paper (base wt. 350 g/m2) at 15 g/m2 coat wt., kept overnight at 25° and 65% relative humidity, and calendered at 60° and 85 kg/cm linear pressure to give a specimen with brightness 77.6%, drying time for printing 20 min, and brightness loss 5.2% after 20 h in UV light, useful for offset printing.

Paper having improved dry strength: Paper having improved dry strength. (Kyoritsu Organic Industrial Research Laboratory, Japan). Jpn. Kokai Tokkyo Koho JP 59076997 A2 2 May 1984 Showa, 7 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: D21H003-38; D21H003-12. ICA: D21H003-48. APPLICATION: JP 82-185578 22 Oct 1982. DOCUMENT TYPE: Patent CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) The title paper is manufd. by adding to the pulp slurry a mixt. of 3-50% water-sol. polycations contg. N in the main chain with sp. viscosity of 10% aq. soln. (hsp) 0.2-15, cation content 4-15 mequiv/g, and 50-97% water-sol. amphoteric copolymers [reduced viscosity at 0.1% in 1N NaCl at pH 3 (hr) 1-5] of aminoethyl (meth)acrylate salts 3-15, (meth)acrylic acid or esters or salts thereof 3-20, (meth)acrylamide 45-90, and (meth)acrylonitrile 0-20 mol %. Thus, 0.45 part 20% aq. Me2NH-epichlorohydrin condensate [25988-97-0] (cation content 10.2 mequiv/g, hsp 0.8), 2.55 parts 20% aq. acrylamide-acrylic acid-dimethylaminoethyl methacrylate sulfate copolymer [63570-34-3] (monomer mol ratio :10, hr 4), and alumina were mixed and added to 100 parts 1% slurry of conifer unbleached kraft pulp (degree of beating 400 mL). Paper made from the slurry had burst factor 7.88.
