A pressure-sensitive adhesive film for temporary protection of metal surfaces which comprises: - a backing comprising at least one layer of polyolefin, - a rubber adhesive coated on one of the sides of the backing, - a varnish based on epoxy-modified silicone coated on the other side of said backing, at a rate from 0.4 to 2.5 g/m 2, said rubber adhesive having a glass transition temperature (Tg), determined by dynamic mechanical analysis (ARES system in plate-plate mode, with a temperature sweep from -193°K to 423°K with a temperature ramp of 5°K/min), greater than 230°K and being obtained by mixing about 5 to 40 wt% (dry extract) of a formulation containing: • 30 to 80 wt%, preferably from 35 to 75 wt%, of a natural rubber or of a mixture of natural rubber(s) and synthetic rubber(s); • 5 to 60 wt%, preferably 20 to 60 wt%, more preferably 30 to 60 wt%, of one or more tackifying resin(s); • 0 to 40 wt%, preferably 0 to 20 wt%, of a plasticizer; • >0 to 6 wt%, preferably >0 to 4 wt%, of a crosslinking agent; • 0 to 4 wt%, preferably 0 to 2 wt%, of one or more antiaging agent(s); in a hydrocarbon-containing solvent, it being understood that the sum of the various constituents of the formulation is equal to 100 wt%; said varnish comprising: • 100 parts by weight of silicone epoxy resin; • 0-150 parts by weight of an adherence modulating system; • >0-20 parts by weight of a cationic photo-initiator; • 0-20 parts by weight of one or more additives selected from an antifoaming agent and fillers that improve sliding, abrasion resistance, and/or bonding of the varnish on the backing film; said pressure-sensitive adhesive film having a width between 950 mm and 2700 mm; said pressure-sensitive adhesive film comprising patterns printed on the backing. - a backing comprising at least one layer of polyolefin, - a rubber adhesive coated on one of the sides of the backing, - a varnish based on epoxy-modified silicone coated on the other side of said backing, at a rate from 0.4 to 2.5 g/m 2, said rubber adhesive having a glass transition temperature (Tg), determined by dynamic mechanical analysis (ARES system in plate-plate mode, with a temperature sweep from -193°K to 423°K with a temperature ramp of 5°K/min), greater than 230°K and being obtained by mixing about 5 to 40 wt% (dry extract) of a formulation containing: • 30 to 80 wt%, preferably from 35 to 75 wt%, of a natural rubber or of a mixture of natural rubber(s) and synthetic rubber(s); • 5 to 60 wt%, preferably 20 to 60 wt%, more preferably 30 to 60 wt%, of one or more tackifying resin(s); • 0 to 40 wt%, preferably 0 to 20 wt%, of a plasticizer; • >0 to 6 wt%, preferably >0 to 4 wt%, of a crosslinking agent; • 0 to 4 wt%, preferably 0 to 2 wt%, of one or more antiaging agent(s); • 30 to 80 wt%, preferably from 35 to 75 wt%, of a natural rubber or of a mixture of natural rubber(s) and synthetic rubber(s); • 5 to 60 wt%, preferably 20 to 60 wt%, more preferably 30 to 60 wt%, of one or more tackifying resin(s); • 0 to 40 wt%, preferably 0 to 20 wt%, of a plasticizer; • >0 to 6 wt%, preferably >0 to 4 wt%, of a crosslinking agent; • 0 to 4 wt%, preferably 0 to 2 wt%, of one or more antiaging agent(s); in a hydrocarbon-containing solvent, it being understood that the sum of the various constituents of the formulation is equal to 100 wt%; said varnish comprising: • 100 parts by weight of silicone epoxy resin; • 0-150 parts by weight of an adherence modulating system; • >0-20 parts by weight of a cationic photo-initiator; • 0-20 parts by weight of one or more additives selected from an antifoaming agent and fillers that improve sliding, abrasion resistance, and/or bonding of the varnish on the backing film; • 100 parts by weight of silicone epoxy resin; • 0-150 parts by weight of an adherence modulating system; • >0-20 parts by weight of a cationic photo-initiator; • 0-20 parts by weight of one or more additives selected from an antifoaming agent and fillers that improve sliding, abrasion resistance, and/or bonding of the varnish on the backing film; said pressure-sensitive adhesive film having a width between 950 mm and 2700 mm; said pressure-sensitive adhesive film comprising patterns printed on the backing.
