PROBLEM TO BE SOLVED: To obtain a tacky adhesive for a polarizing plate excellent in aging stability by compounding an acrylic tacky adhesive contg. an isocyanate cross- linker with a specific tert. amine. SOLUTION: This tacky adhesive is prepd. by compounding an acrylic tacky adhesive contg. an isocyanate cross-linker with a tert. amine having 6-12C alkyl groups. Examples of the amine are tri-n-hexylamine, tri-n-heptylamine, tri-n- nonylamine, tri-n-decylamine, and tri-n-dodecylamine. Examples of the cross- linker are xylene diisocyanate, tolylene diisocyanate, and diphenylmethane diisocyanate. |
