Abstract:
A quantum dot film article including a first barrier layer, a second barrier layer; and a quantum dot layer between the first barrier layer and the second barrier layer. The quantum dot layer includes quantum dots dispersed in a matrix including a cured adhesive composition. The adhesive composition includes an epoxide and a curing agent including: (a) a compound of Formula I: wherein A is a monocyclic or a polycyclic alkylene group, or a monocyclic or a polycyclic heteroalkylene group, and m and n are integers each independently selected from 0 to 5; and (b) a polyether amine compound including at least one of primary and secondary amino groups attached to a polyether backbone. The adhesive composition further includes a radiation curable methacrylate compound.
