Abstract
Provided is an optically clear display-grade adhesive comprising (a) a crosslinked acrylic pressure sensitive adhesive, (b) an organic-soluble and dissociable salt, and optionally (c) a non-hydrophilic plasticizer, wherein the adhesive is electrostatically dissipative transmissive to visible light with low haze. Also provided are with methods of making and using the same.
Claims29
An optically clear display-grade adhesive comprising:
- a crosslinked acrylic pressure sensitive adhesive;
- an organic-soluble and dissociable salt;
- and
- a non-hydrophilic plasticizer,
- wherein the adhesive is electrostatically dissipative and is at least about 80% transmissive to visible light and is below about 10% haze.
An optically clear display-grade adhesive consisting essentially of:
- a crosslinked acrylic pressure sensitive adhesive;
- and
- an organic-soluble and dissociable salt,
- wherein the salt comprises an alkali metal cation and an organic anion.
(canceled)
A method of making an optically clear display-grade adhesive comprising:
- providing at least one acrylic monomer and optionally at least one comonomer, and optionally a photoinitiator;
- blending the monomer(s) with an organic-soluble dissociable salt and a crosslinker to form an adhesive precursor composition;
- providing the adhesive precursor composition onto a first release liner;
- and
- activating the crosslinker to form a crosslinked acrylic pressure sensitive adhesive,
- wherein the adhesive is electrostatically dissipative, and optionally wherein the adhesive is at least about 80% transmissive to visible light and is below about 10% haze.
