Abstract
The adhesion of acrylic pressure sensitive adhesives to plastic substrates is improved by the presence of the adhesive of an effective amount for such adhesion improvement, e.g., from about 0.3% to about 4.0%, by weight of the adhesive when in liquid form, of a monoalkyl acid phosphate.
Claims5
An improved liquid acrylic pressure sensitive adhesive formulation which comprises a polyacrylate elastomer component and which, when in dried form in a pressure sensitive product, has increased adhesion to a plastic substrate due to the presence in said adhesive formulation of an effective amount for said adhesion of a monoloweralkyl acid phosphate.
