1. An ink jet printed flexible film comprising:

(a) a polymer film having a thickness in the range of from 30 to 500 μm;

(b) at least one ink-receptive layer comprising inorganic particles and a binder, said at least one ink-receptive layer comprising pores; and

wherein said ink-receptive layer further comprises a cross-linked polymer of polymerizable and/or crosslinkable monomeric or polymeric compounds having at least one (meth)acrylate moiety in the amount of more than 6% by weight based on the weight of the ink-receptive layer in the pores of said at least one ink-receptive layer, wherein the cross-linked polymer is crosslinked via the (meth)acrylate moieties, and wherein said ink jet printed flexible film is formed by a method that comprises applying at least a portion of the polymerizable and/or crosslinkable monomeric or polymeric compounds to the ink receptive layer after the pigments of the inkjet ink have been applied to the at least one ink-receptive layer.
