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 glycerol 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 a moisture-proof adhesive coating composition comprising an antioxidant and a blend of an amorphous polymer of propylene, a crystalline polymer of propylene and a resinous mixture of C.sub.4 to C.sub.10 hydrocarbons derived from the polymerization and hydrogenation of a petroleum feedstock and to a method of using and producing the blend of this invention.

Abstract: A wetness indicating hot-melt adhesive which changes color quickly in response to the presence of moisture is disclosed which contains 20 to 70 wt. % of polymer, 35 to 100 wt. % of which is water sensitive polymer; 27 to 60 wt. % of organic acid which is selected from a high acid number fatty acid or a combination of a high acid number fatty acid and other high acid number organic acids; 0 to 30 wt. % of water soluble wax and a wetness indicating agent which changes the color of the composition rapidly in response to moisture therein.

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.

Abstract: This invention relates to water-activatable hot-melt adhesives. More specifically, it relates to such adhesives having non-blocking qualities at high humidity at higher pressures than have been used heretofor.
