Abstract:

A solution with a salt-sensitive polymer binder for use in fibrous webs, where the binder contains a copolymer comprising repeat units derived from butyl acrylate, methyl methacrylate and amino functionalized alkyl acrylate or methacrylate or amino functionalized alkyl acrylamide or methacrylamide optionally including monomers such as vinyl acetate and/or vinyl acetate/ethylene. The binder solution is prepared by emulsion-polymerizing a copolymer and then neutralizing the copolymer with acid to make it water soluble. The binders are particularly suitable for strengthening nonwoven fibrous webs in disposable articles such as wet-wipes, personal care products, diapers, and the like and retain their salt-sensitivity with or without divalent metal scavengers.

Abstract:

The present invention relates to a liquid starch dispersion for paper coating where the dispersion has to percent by weight of starch, and the starch contains from to percent by weight of at least one cationic starch. The liquid starch composition is characterized in that a percent by weight starch solids dispersion has a C. viscosity of from to cps both initially, and also upon storage at room temperature for days. The dispersion preferably contains a blend of cationic starch and ASA starch. The liquid starch dispersion is useful in paper and paperboard coating processes, as a rheology modifier, a structurant, and/or a binder, all at the same time. The liquid starch dispersion provides good coating holdout, gloss, and stiffness properties. The cationic nature of the starch coating improves printability with anionic inks, and makes the coatings useful for ink-jet and photographic papers.

International Classification:

C08K003/26
C08K003/34

US Classification:

524/425000, 524/492000

Abstract:

The present invention relates to a coating composition for fibrous substances containing 25 to 75 percent by weight of pigment, and 0.5 to 25 weight percent of a polymer comprising 1 to 15 percent by weight of one or more monomers having sterically hindered secondary amine groups and 10 to 40 weight percent of a carboxylic acid monomer. The coating is useful on fibrous and non-fibrous substrates on which liquid inks will be fixed. The non-ionic polymer becomes cationic when contacted by anionic inks, and the cationic nature of the coating provides the substrate with an excellent point of attachment for inks and dyes, resulting in bright, crisp printed images. The coating is especially useful for ink-jet printing on paper, paperboard, textiles, non-wovens, wood, and films.

US Classification:

524/543000, 428/500000

Abstract:

The present invention relates to a coating composition for fibrous substrates made up of 0.5 to 25 percent by weight of a water-insoluble emulsion polymer comprising from 0.4 to 3 mole percent of one or more cationic monomer units and at least 50 mole percent of at least one vinyl ester monomer; 25 to 75 percent by weight pigment; and water. The coating is useful on fibrous substrates on which liquid inks will be fixed. The cationic nature of the coating provides the substrate with an excellent point of attachment for anionic inks and dyes, resulting in bright, crisp printed images. The coating is especially useful for inkjet printing on paper, paperboard, textiles, non-wovens, and wood.

US Classification:

442/164000, 442/327000, 442/149000

Abstract:

The present invention is directed to a fibrous nonwoven material made of chemically bonded fibers, where the fibers are bound with a polymeric binder in an amount which is sufficient to bind the fibers together to form a self-sustaining web, and where the binder comprises from 55 to 96 percent by weight of a film-forming polymer; from 4 to 45 percent by weight of one or more opacifying agents; and 0 to 2 percent by weight of one or more adjuvants, based on the binder composition solids. The binder composition provides opacity to the nonwoven material. The binder composition is especially useful in light basis weight nonwovens, and provide high opacity and tensile strength both dry and wetted.

International Classification:

B32B 27/02

US Classification:

442164

Abstract:

Wallcoverings which include a nonwoven synthetic substrate and a water-based ground coating which is applied thereto. The ground coating includes emulsion polymer pigment binders and a mineral pigment composition. The ground coating provides the nonwoven substrate with superior printing and durability properties, enabling the production of wallcoverings which may be printed with a decorative design. The wallcoverings are desirable for environmental, health, and safety reasons.

Abstract:

Disclosed are surfactant-stabilized latex emulsions which can be used as binders in paper coating compositions. Such latex emulsions comprise an interpolymer formed by emulsion polymerizing monomers selected from vinyl esters, e.g., vineyl acetate; ethylene; certain unsaturated mono- and di-carboxylic acid materials such as acrylic acid or maleic anhydride; and certain polyethylenically unsaturated cross-linking co-monomers such as diallyl phthalate. These latex emulsions are stabilized with surfactants which are substantially free of environmentally suspect alkyl phenol ethoxylates (APEs). The paper coating compositions containing latex emulsion binders of this type exhibit especially desirable coating strength as quantified by the Dry Pick Values (as defined herein) which such compositions provide.
