Claims3
An opacifying adhesive composition adapted to remain opaque in wet condition for pressure sensitive label application, said opacifying adhesive comprising a proportionate amount of adhesive component and a pigment component sufficient to maintain opacity when exposed to an aqueous environment for at least 1 hour and a peel adhesion of at least 1 N/inch and a loop tack of at least 2 N/inch in said pressure sensitive application;
- wherein said pigment component comprises surface-coated TiO2;
- wherein said pigment component is present in a weight range of about 10% to about 50% of said adhesive component;
- and
- wherein said opacity in wet condition is about 80% to 90%.
