ABSTRACT:
A polyester film containing organic particles comprising a matrix polymer and fine polymer particles is provided. The fine particles are interpenetrating network type cross-linked fine polymer particles, each particle containing, in its cross-linked polymer network, a hydrophilic polymer in an amount of 1 to 40% by weight which is not substantially bonded to the cross-linked polymer chemically. The cross-linked polymer is a vinyl type polymer or a siloxane type polymer comprising as its main components a polymerizable monomer and at least one cross-linking monomer contained in an amount of 5% by weight or more based on the total weight of the monomers. The interpenetrating network type cross-linked fine polymer particles have an average particle size in the range of 0.01 to 5 .mu.m and are contained in the film in an amount of 0.001 to 5.0% by weight.
