Zusammenfassung:	PROBLEM TO BE SOLVED: To provide improved adhesives that can be applied at low temperatures, to a variety of substrates, and under a variety of environmental conditions by solving the following problem: when certain optical products are exposed to harsh environmental conditions, such as heat, UV (solar) light and water, a field of vision is optically obstructed.SOLUTION: A method and composition for forming an adhesive bond is described. The method includes: depositing an aqueous dispersion on a substrate to form a selectively activatable coating, the aqueous dispersion including (A) a polymer capable of forming an adhesive; (B) at least one dispersing agent, and (C) at least one of a tackifying resin, a wax, or an oil, wherein the dispersion has at least one of an average particle size of from about 0.1 to about 100 microns and a polydispersity of less than 5; and selectively activating at least a portion of the coated substrate to form the adhesive bond.
