Abstract
This invention provides an alkali-soluble resin coating composition, more particularly an aqueous floor polish composition, comprising water, at least one alkali-soluble polymeric film forming agent, preferably solubilized in water using ammonia or an ammonia derivative, a polyvalent metal crosslinking agent, and a plasticizing agent, wherein the improvement comprises at least a portion of the plasticizing agent being formed of a weak carboxylic acid, such as a tertiary alkyl monocarboxylic acid, or an unsaturated primary carboxylic acid, each acid having an average of from about 6 to 30 carbon atoms per molecule, or combinations thereof. Such compositions have one or more improved properties such as greatly reduced ammonia odor as compared with the same compositions using only conventional plasticizers such as tributoxyethyl phosphate, reduced pH of the composition to increase ease of handling the composition, improved or equal coating film leveling, and improved gloss development and mark resistance with good self-sensitivity for less buildup upon recoating.
