Abstract: PURPOSE: To efficiently obtain a paper product well maintaining a filler or the like from a paper material containing foreign matters in a shorter draining time than a conventional method by using a specified polymer as a draining agent and holding agent to drain water from the paper material. CONSTITUTION: The paper product is obtd. by subjecting a paper material containing foreign matters to draining treatment in the presence of a polymer having units expressed by formula I and formula II and having >=130 K-value (in 5 wt.% aq. soln. of sodium chloride under the conditions of 0.1 wt.% polymer concn. at 25 deg.C measured by H.Finkentscher method) and having and R is H and/or a 1-6C alkyl group. The aforementioned polymer is prepared by (co)polymerizing an N-vinylamide expressed by formula III such as N-vinyl formamide to obtain the (co)polymer having the unit I, and then hydrolyzing the (co)polymer in an acid at 50 to 120 deg.C until

Abstract: Rhodamine derivatives of the formula where R , R , R and R are each hydrogen or optionally substituted C1-C4-alkyl or R and R together or R and R together are in each case 1,3-propylene, which may be substituted, R , R , R and R are each hydrogen or methyl, R is hydrogen, optionally substituted C1-C4-alkyl or a radical of the formula (C2H4O-)nH, where n is 2 or 3, and An is the equivalent of an anion which is derived from a chain-growth or step-growth polymer which in either case contains acid groups, novel cyclic rhodamine dyes, and the use of the novel rhodamine derivatives and cyclic rhodamine dyes for dyeing polyacrylonitrile fibres, for incorporation into polymers or for preparing inks.

Abstract: PURPOSE: To prepare sizes for paper, excellent in a sizing effect by dissolving or dispersing a specific modified product of a copolymer of a monoolefin and maleic anhydride or the like in an aqueous medium. CONSTITUTION: Copolymers having 800-100,000 molecular weight are obtained by copolymerizing (a) 12-40C monoolefins with (b) maleic anhydride or itaconic anhydride. The anhydride groups of the copolymers are amidated with morpholine to form semiamides which are partially or completely neutralized with an alkali (or alkaline earth) metal base, ammonia or an amine in an aqueous medium. The resultant product is used as sizes for paper stock or the surface of paper in a form of aqueous solution or dispersion.
