Abstract: A wetness indicating hot-melt adhesive which changes color in response to the presence of moisture is disclosed, which contains 20 to 70 wt. % of polymer, about 28 to 10 wt. % of which is water sensitive polymer; 25 to 60% of organic acid which is selected from a high acid fatty acid, or rosin acid, or a combination thereof; 0 to 40% of water soluble wax; 0 to 60 wt. % of glycerlo monostearate; 0 to 55 wt. % of hydrogenated castor oil; 0 to 15 wt. % of polyalkylene wax; 0 to 60 wt. % of compatible plasticizer; and a wetness indicating agent which changes the color of the composition in response to moisture therein. The time of response of the color change can be controlled from about one second to a somewhat larger value as desired.

Abstract: This invention relates to water-soluble, pressure-sensitive, hot-melt adhesives; and more specifically to hot-melt adhesives for labels and pressure-sensitive labels. The labels can be readily removed by application of water to the adhesive to facilitate peeling from the article; the adhesives are based upon certain vinyl pyrrolidone polymers.
