Label assemblies for redeemable coupons, pressure-sensitive labels, lottery tickets and the like. A strip of redeemable coupons comprises an indefinite length web coated with a release coating, at least one coupon on the web comprising a sheet of stock material, a first dry coating layer covering the surface of the stock material, a second dry coating covering the first dry coating and a pressure-sensitive adhesive layer over the second dry coating and adhesively securing the coupons to the web. The first and second dry coating layers are substantially incompatible so that they separate from one another when the coupon, applied to an uncoated surface, is pulled therefrom. The first and second layers have shear and tensile strength therebetween greater than the tensile strength between the pressure-sensitive layer and the web so that the coupons can be first separated from the backing web and then applied to articles, and thereafter removed from the articles, leaving the adhesive layer and the second dry coating layer on the container. Lottery tickets having two incompatible layers, one of which is a pigmented layer, are also disclosed.
