    Abstract: A composite comprises at least one layer which includes a composite comprising (a) from 1 to 99% by weight of a solid (I) with a primary particle size of from 5 nm to 100 mum or a mixture made from at least two solids, (b) from 99 to 1% by weight of a polymeric binder (II) which includes: (IIa) from 1 to 100% by weight of a polymer or copolymer (IIa) which has, along the chain, terminally and/or laterally, reactive groups (RG) which are capable of crosslinking reactions when exposed to heat and/or UV radiation, and (IIb) from 0 to 99% by weight of at least one polymer or copolymer (IIb) which is free from reactive groups RG, where the at least one layer has been applied to at least one second layer comprising at least one conventional separator.

    Abstract: The compositions comprise: (a) from 1 to 99% by weight of a pigment (I) having a primary particle size of from 5 nm to 100 mum which is a solid Ia or a compound Ib which acts as cathode material in electrochemical cells or a compound Ic which acts as anode material in electrochemical cells or a mixture of the solid Ia with the compound Ib or the compound Ic, (b) from 1 to 99% by weight of a polymeric material (II) which comprises: (IIa) from 1 to 100% by weight of a polymer or copolymer (IIa) which has, as part of the chain, at the end(s) of the chain and/or laterally on the chain, reactive groups (RG) which are capable of crosslinking reactions under the action of heat and/or UV radiation, and (IIb) from 0 to 99% by weight of at least one polymer or copolymer (IIb) which is free of reactive groups RG.
