A co-extruded multi-layer biaxially oriented polyester film comprising a primary polyester layer and a dissimilar secondary polyester layer adjacent to the primary polyester layer, wherein the primary polyester layer and the secondary polyester layer each comprise a glycidyl ester of a branched monocarboxylic acid, wherein the monocarboxylic acid has from 5 to 50 carbon atoms, and wherein said glycidyl ester is in the form of its reaction product with at least some of the end groups of the polyester; and use thereof as a component of a photovoltaic cell.

Co-extruded multi-layer polyester films having hydrolytic stability and improved delamination resistance

A process for the manufacture of a reflective conductive film comprising: (i) a reflective polymeric substrate comprising a polymeric base layer and a polymeric binding layer, wherein the polymeric material of the base layer has a softening temperature T, and the polymeric material of the binding layer has a softening temperature T; and (ii) a conductive layer comprising a plurality of nanowires, wherein said nanowires are bound by the polymeric matrix of the binding layer such that the nanowires are dispersed at least partially in the polymeric matrix of the binding layer, said process comprising the steps of providing a reflective polymeric substrate comprising a polymeric base layer and a polymeric binding layer; disposing said nanowires on the exposed surface of the binding layer; and heating the composite film to a temperature Twherein Tis equal to or greater than TS&#x2212;HS, and Tis at least about 5&#xb0; C. below T.
