Resin finishing of corrugated paper boards

Resin finishing of corrugated paper boards. Suzuki, Hiroo; Tada, Hiroshi (Toyo Ink Mfg. Co., Ltd., Japan). Japan. Kokai JP 52040610 29 Mar 1977 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: D21H001-40. APPLICATION: JP 75-113593 22 Sep 1975. DOCUMENT TYPE: Patent CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Section cross-reference(s): 42 Water-thinned resin coating compns., useful for coating and reinforcement of corrugated paper boards, were prepd. by mixing aq. solns. of alkali-neutralized acrylic acid copolymers with emulsions of N-substituted methylol group-contg. (meth)acrylamide copolymers. Thus, a copolymer [35209-54-2] obtained by heating a mixt. of styrene 50, acrylic acid 50, iso-PrOH 50, and AIBN 3 parts was neutralized with 30 parts of a 25% aq. NH3 soln. and dild. with 153 parts water to give a 30% solids soln. A polymer [63322-65-6] emulsion [40% solids; 30 parts, based on resins; obtained by emulsion polymn. of a mixt. of Me methacrylate 50.0, Et acrylate 45.0, N-methylolacrylamide 2.5, fumaric acid 2.5 (NH4)2S2O8 (20% soln.) 2.5, NaHSO3 (10% soln.) 2.5, anionic surfactant (20% soln.) 15.0, nonionic surfactant (20% soln.) 15.0, water 113.0, and aq. ammonia 2.0 parts] was mixed with 70 parts (based on resins) of the neutralized aq. resin soln., applied to a corrugated paper board, and dried 2-4 min at 130.degree. to improve the ring crush compressive strength from 28.95 to 59.45 kg and the bursting strength from 2.69 to 4.61 kg/cm2.

Use of carboxylated polymers with dextrins and proteins as pigment dispersants

Use of carboxylated polymers with dextrins and proteins as pigment dispersants. Herrmann, Manfred; Belde, Horst; Denzinger, Walter; Leiter, Herbert; Zimmermann, Norbert (BASF A.-G., Germany). Ger. Offen. DE 4024422 A1 6 Feb 1992, 8 pp. (Germany).There are some reagents with their cas registry numbers 54452-17-4 and 35209-54-2 are used in this study. CODEN: GWXXBX. CLASS: ICM: C08L025-00.

DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 46 Mixts. of 10-70% water-sol. salt of a copolymer of 40-80% vinylarene, 20-60% unsatd. acid and/or anhydride, and 0-20% other monomers, 30-90% dextrin and/or natural proteins, and 0-10% other dispersants are used in the prepn. of pigment dispersions. A mixt. of :60 acrylic acid-maleic anhydride-styrene copolymer ammonium salt 45, dextrin 45, and ethoxylated propoxylated ethylenediamine 10% was used as a dispersant for carbon black. .
