Abstract: This disclosure is related to photo-stable chromophores which are useful in various applications. Chromophores disclosed herein include a bis-triazole core, two electron-donors at C-4 and C-8, and two groups derived from pentaerythritol (R═OR5) or 1,1,1-tris(hydroxymethyl)methane (R═H) at N-2 and N-6. Such structures have been proven to have greater then five times higher photo-stability than their analogs with simpler alkyl groups at N-2 and N-6.

Abstract: An electrically peelable adhesive composition including: an acrylic polymer, in which the acrylic polymer is a product of reacting a mixture including a polar monomer including a hydroxyl group and a polar monomer including an alkoxy group; an ionic liquid including a cation, a first anion and a second anion, in which the first anion is an alkyl sulfonate and the second anion is a sulfonylimide; and a vinyl compound including nitrogen.
