  "description_excerpt": "This disclosure relates generally to aqueous compositions used as coatings, inks, adhesives, and the like that incorporate a water soluble, quick-setting additive. More specifically, this disclosure relates to aqueous compositions that include latex particle dispersions with water soluble polymers or polymeric adducts being mixed therewith.\n\nThe statements in this section merely provide background information related to the present disclosure and may not constitute prior art.\n\nLatex products are widely used in a variety of coatings, adhesives, and inks because they offer several benefits, including the ease in which they can be handled and the absence of any substantial amount of volatile organic compounds (VOCs). One specific example of such a latex product is the acrylic latex compositions used in traffic marking paints. Due to the market demand for products that exhibit a shortened setting time, the coating industry has widely adopted coagulation technology for use in latex products. Within the confines of such coagulation technology, protonated polyfunctional amines destabilize the anionically-stabilized latex particles present in the latex products after they are coated onto a substrate. However, in order to retain the stability of the modified latex particles in the latex product prior to application (e.g., during storage), a volatile amine is added to the latex product in order to increase the pH to a level that prevents the protonation of the polyfunctional amine When the latex product is applied on to a substrate, the volatile amine escapes or evaporates from the applied coating composition.",
