Abstract
A fluid activatable adhesive for a liner-free label and methods of using are described. Preferably, the adhesive composition includes a polymer, such as an emulsion polymer formed from monomers selected from the group consisting of butyl acrylate, 2-ethylhexyl acrylate, methyl acrylate, 2-acrylamido-2-methylpropane sulfonic acid (AMPS), a salt of AMPS, such as its sodium salt, styrene, and combinations thereof. The adhesive composition adheres to the liner-free label to the surface of a substrate that is at room temperature, at room temperature and wet, cold, or cold and wet. In preferred embodiments, the substrate is glass or plastic, such as polyethylene terephthalate.
