A method of enhancing the dewatering of a paper sheet on a paper machine comprising adding to the paper sheet about 0.05 lb / ton to about 15 lb / ton, based on dry fiber, of one or more aldehyde functionalized polymers comprising amino or amido groups wherein at least about 15 mole percent of the amino or amido groups are functionalized by reacting with one or more aldehydes and wherein the aldehyde functionalized polymers have a molecular weight of at least about 100,000.

A composition is provided, which comprises a water-soluble salt of a divalent metal; a complexing agent having an affinity for the divalent metal; and an optical brightening agent. Methods of using the composition, and recording sheets which include the composition, are also disclosed.

The present invention relates to a soft, thick, single-ply, printed, absorbent paper product having a Yankee side and an air side wherein the absorbent paper is printed on before or after embossing on the Yankee side, air side, or both sides, said absorbent paper exhibiting a serpentine configuration. This inventions also relates to a process for the manufacture of such absorbent paper product having a basis weight of at least about 12.5 lbs. per 3000 square foot ream and having low sidedness, said tissue exhibiting: a specific total tensile strength of between 40 and 200 grams per 3 inches per pound per 3000 square foot ream, a cross direction specific wet tensile strength of between 2.75 and 20.0 grams per 3 inches per pound per 3000 square foot ream, the ratio of MD tensile to CD tensile of between 1.25 and 2.75, a specific geometric mean tensile stiffness of between 0.5 and 3.2 grams per inch per percent strain per pound per 3000 square foot ream, a friction deviation of less than 0.250, and a sidedness parameter of less than 0.30. These single-ply, printed, absorbent paper products in the form of unembossed or embossed single-ply bathroom tissue, facial tissue, or napkin are useful articles of commerce. The single-ply absorbent paper products exhibit a printed sidedness value of DELTAE of less than 2.

Compositions comprising a blend of two or more paper strengthening agents have improved stability compared with previously known paper strengthening agents. One component is a polymeric paper strengthening agent, preferably a wet strengthening agent. The other component is a stabilized polyacrylamide prepared by (1) reacting a first portion of glyoxal with a polyacrylamide having pendant amide groups to form a first reaction mixture comprising polyacrylamide; (2) adding an acid to the first reaction mixture to form a second reaction mixture having a reduced pH and comprising the polyacrylamide; and (3) adding a second portion of glyoxal to the second reaction mixture to form the stabilized polyacrylamide. If desired, an aldehyde scavenger can be included in one or more of step (1), step (2), step (3), or the stabilized polyacrylamide. Such compositions can be used to enhance the strength of paper, particularly the wet strength of paper.

The present invention relates to a soft, thick, single-ply tissue having a serpentine configuration and to a process for the manufacture of such tissue product having a basis weight of at least about 15 lbs. / 3,000 square foot ream and having low sidedness, said tissue exhibiting:a specific total tensile strength of between 40 and 75 grams per 3 inches per pound per 3000 square feet ream, a cross direction specific wet tensile strength of between 2.75 and 7.5 grams per 3 inches per pound per 3000 square feet ream, the ratio of MD tensile to CD tensile of between 1.25 and 2.75, a specific geometric mean tensile stiffness of between 0.5 and 1.2 grams per inch per percent strain per pound per 3000 square feet ream, a friction deviation of less than 0.225, and a sidedness parameter of less than 0.275.

Disclosed is a composition suitable for atomizing without excessive aerosolization in the form of an oil-in-water emulsion comprising: a) a continuous aqueous phase, and b) a discontinuous oil phase wherein the rheology of the aqueous phase is modified by the addition of a water-in-oil emulsion comprising: i) a high molecular weight polymer in a discontinuous aqueous phase, and ii) a continuous organic solvent phase. Preferred embodiments of the present invention relate to compositions for softening an absorbent paper tissue comprising a) a quaternary ammonium softening active ingredient; b) an electrolyte; c) a high molecular weight polymer emulsion comprising: i) from about 20% to about 40% by weight of the premix of a high molecular weight polymer; ii) from about 40% to about 60% of water; and iii) from about 20% to about 40% of an organic solvent; and d) a vehicle in which said softening active ingredient is dispersed.
