  • Patent number: 9273236
    Abstract: The present invention relates to aqueous polymer dispersions having a polymer content of at least 55% by weight that are suitable for pressure sensitive adhesives. The invention also relates to a process for preparing these aqueous polymer dispersions and the use of the aqueous polymer dispersions in pressure sensitive adhesives and, respectively, pressure sensitive adhesive compositions, especially in pressure sensitive adhesives for transparent substrates, such as plastics labels. The aqueous polymer dispersions have a polymer content of at least 55% by weight, based on the total weight of the dispersion. The polymer is composed of ethylenically unsaturated monomers and has a glass transition temperature below ?10° C., in which the dispersed polymer particles have a polymodal particle size distribution, in which at least 70% by weight of the polymer particles have a particle diameter of below 350 nm.

  • Patent number: 9200182
    Abstract: The present invention is a paint coat-protecting removable pressure-sensitive adhesive sheet comprising a base sheet, and a pressure-sensitive adhesive layer that is provided on the base sheet, the pressure-sensitive adhesive layer being formed of an emulsion pressure-sensitive adhesive composition that includes an emulsion of an ethylene-vinyl carboxylate copolymer as a main component. The present invention provides a paint coat-protecting removable pressure-sensitive adhesive sheet that does not cause swelling, whitening, and adhesive transfer even when the pressure-sensitive adhesive sheet is attached to the surface of a paint coat that has not been sufficiently dried (i.e., contains a small amount of solvent) or has not been sufficiently cured after drying, and removed from the paint coat.

  • Patent number: 9175181
    Abstract: In one example, an anti-fouling latex ink includes a liquid vehicle, a pigment dispersed in the liquid vehicle, latex dispersed in the liquid vehicle, and a polystyrene anti-fouling additive dispersed in the liquid vehicle as a free solution. An illustrative method of formulating a latex inkjet ink includes forming a liquid vehicle with water as primary solvent, dispersing pigments in the liquid vehicle, and adding 0.01 wt % to 1 wt % of a polystyrene antifouling additive as a free solution to the liquid vehicle.

  • Patent number: 8993668
    Abstract: What are described are polyvinyl ester dispersions which are prepared in a multistage process and have a low content of polymerized acids or acid anhydrides. They can be obtained by a multistage process in which a polyvinyl ester dispersion is obtained in a first stage, monomers in dissolved or pure form are added to the reaction mixture in a second stage and then the polymerization is started again. The polymer dispersions obtained in this way are notable for a low coagulum content and for increased tensile strengths of the films formed therefrom.

  • Patent number: 8957134
    Abstract: A process for encapsulating pigment dispersions is provided where a pigment is dispersed with a polymeric dispersant in an aqueous solvent system. The free polymer dispersant in the pigment dispersion is limited to less than 0.12 grams per gram of pigment. This dispersed pigment is then encapsulated by adding acrylate monomers and optionally acrylic and vinyl monomers and polymerizing. In the encapsulated pigment dispersion the weight ratio of final free polymer to polymer found to the final encapsulated pigment is less than 0.9. The free polymer dispersant is measured by a centrifugation method and the final free polymer is measured by a density gradient centrifugation method. Such encapsulated pigment dispersions may be used in inkjet inks and are stable to heat, aging test conditions, and solvent challenges. Prints from these inks have better durability.
