The present invention relates to a process for preparing an aqueous dispersion of multiphase occluded polymer particles comprising the steps of a) contacting, under emulsion polymerization conditions, first monomers and a chain transfer agent to form an aqueous dispersion of first polymer particles having a T.sub.g in the range of from −30° C. to 30° C.; then b) contacting the aqueous dispersion of first polymer particles with a second monomer under emulsion polymerization conditions to form an aqueous dispersion of second polymer particles occluded within the first polymer particles, wherein the first monomers a phosphorus acid monomer or a salt thereof; and the second monomer comprises at least 90 weight percent methyl methacrylate. The aqueous dispersion of occluded polymer particles arising from the process of the present invention is useful in a formulation that can be used to prepare a water-resistant blister free LASD coating.

Curable compositions, cured compositions, articles containing the curable or cured compositions, and methods of making the articles are provided. More particularly, the curable compositions contain a (meth)acrylate-based polymer having pendant (meth)acryloyl groups, at least one monomer having a single ethylenically unsaturated group, a photoinitiator that includes an acyl phosphine oxide, and a thixotropic agent. The curable compositions can be printed or dispensed, if desired, and the cured compositions are pressure-sensitive adhesives.

Provided herein are aqueous dispersions. The aqueous dispersions can comprise a first copolymer derived from one or more ethylenically unsaturated monomers, and a second carboxy-functional copolymer derived from one or more carboxylic acid-containing monomers. The aqueous dispersions can be used to prepare low- or zero-VOC aqueous coating compositions that possess desirable properties, including good block resistance and scrub resistance. Coatings and coating formulations comprising the aqueous dispersion, as well as methods of making and using the same are also provided.

The present invention provides a polymerizable composition containing a specific polymerizable compound and a fluorosurfactant having a specific polyoxyalkylene skeleton and having specific molecular weight. The invention also provides an optically anisotropic body, a retardation film, an antireflective film, and a liquid crystal display device that are produced using the polymerizable composition of the present invention. The present invention is useful because, when an optically anisotropic body is produced by photo-polymerization of the polymerizable composition, three features including the leveling properties of the surface of the optically anisotropic body, offset onto the substrate, and liquid crystal alignment can be improved simultaneously.
