ABSTRACT:
Water dispersible, hydrophilic, repulpable, water-activatable, acrylic polymers are provided. The polymers are non-tacky when dry, but become tacky when wet, and exhibit high peel strength on a variety of substrates. The polymers comprise an acrylic-based polymer prepared by emulsion polymerization of 40 to 70% by weight of one or more alkyl acrylates, the alkyl group of which has from 4 to 8 carbon atoms; 10 to 20% by weight of methacrylate; 2 to 15% by weight of vinyl acetate; and 10 to 25 percent by weight of methacrylic acid and/or acrylic acid; and a positive amount up to about 30% by weight of methyl methacrylate. Some embodiments also include a short chain hydroxyalkyl methacrylate. Also provided are ink jet-imprintable, water-activatable constructions comprising a layer of water-activatable polymer, coated on a release liner or other surface. Optionally, a water-resistant transparent film layer is disposed between the polymer and release liner or used in place of the release liner. The constructions are suitable for use in ink jet printers and can be used to transfer an image to a substrate.
