REMOVABLE LABELS Abstract of the Disclosure There are provided a removable label stock and process for its preparation. The stock 10 comprises discontinuous emulsion adhesive segments 12 on at least a portion 14 of one side of a face thereof. The amount of adhesive present for contact with a smooth surface is from about 10 percent to about 30 percent of the amount of adhesive which would have occupied the portion if the face stock were continuously coated with the adhesive. The emulsion adhesive segments have an average height, relative to the surface of the face stock, of from about 15 to about 35 microns: a room-temperature storage modulus of from about 2 x 105 to about 1.5 x 106 Pascal at a deformation rate of about 104 radians per second, a room-temperature storage modulus of from about 4 x 104 to about 5 x 105 Pascal at a deformation rate of about 102 radians per second, a room-temperature storage modulus of from about 1 x 104 to about 8 x 104 Pascal at a deforma- tion rate of about 10-2 radian per second, and a room- temperature storage modulus of from about 6 x 103 to about 7 x 104 Pascal at a deformation rate of about 10-3 radian per second: a 180° peel strength on a stainless steel panel, having a roughness of about 0.5 micro-inch, of from about 0.5 pound to about 2 pounds per inch at a coating weight of about 40 grams/m2; and a glass-transi- tion temperature of less than 250° Kelvin.
