description ABSTRACT The invention relates to a biaxially oriented multilayer transparent film comprising at least two layers of polyester, respectively a core layer and at least one outer layer, which can be identical or different, wherein: i) at least the core layer comprises at least one biaxially oriented transparent polyester PEI, more preferably an aromatic polyester, and, further more preferably, a polyethylene terephthalate, ii) at least one of the outer layers comprises, on the one hand, at least one biaxially oriented polyester PE2, more preferably an aromatic polyester, and, further more preferably, a polyethylene terephthalate, and, on the other hand, particles coming from the reaction between at least one metal compound and at least one monomeric or oligomeric unit of PE2, said particles having more preferably a d50 -as ?m and following an order of preference - between 0.5 and 5; between 1.0 and 4, and between 1.5 and 3.0. The invention also relates to the manufacture of this film and its applications as a laminate in particular in the backsheets of photovoltaic cells.
