Abstract (en)

[origin: CA2329838A1] Water-activatable acrylic polymers and image transfer constructions made therewith are provided. The polymers are non-tacky to the touch when dry, but become tacky when activated by water, such as the water in the ink of an ink jet printer. The polymers are acrylic copolymers prepared by emulsion polymerization of a monomer mixture that preferably includes at least one alkyl acrylate, methyl acrylate, vinyl acetate, methacrylic acid and acrylic acid. Image transfer sheets made with the water-activatable polymers include a flexible backing, at least one water-impermeable layer, at least one layer of water-activatable polymers, and a protective detack layer.
