A motion picture intermediate film has on one side of a support material, in order, an antihalation undercoat and at least one silver halide emulsion layer; and on the opposite side of the support a transparent, process surviving antistatic backing layer. The transparent, antistatic backing layer retains its antistatic properties after photographic film processing so that the motion picture intermediate film is protected from the generation of static charge during high speed printing of, for example, motion picture print films. The antistatic backing layer of the invention has a resistivity of less than about 1&times;10,&OHgr;/&square; after film processing. In a most preferred embodiment, the motion picture intermediate film of the invention is used to print images onto a motion picture print film that has a transparent antistatic backing layer. In accordance with the invention, use of a motion picture intermediate film as described above in making multiple prints onto motion picture print film results in surprisingly decreased levels of dirt and other image defects in the projected motion picture print film images, especially where such intermediate film is used to print onto print films having a process surviving antistatic backing layer.

A flexible paint-coated film which has a basecoat-clearcoat appearance and good mar-resistance is prepared by coating a polyurethane paint layer on a flexible polymeric carrier film. Over the paint layer is coated a clear polyurethane layer. Over the latter is coated a relatively thin layer of a clear polyurethane composition obtained by the reaction of a polyisocyanate with a reactive poly(dialkylsiloxane). Preferably, the latter has at least two active-hydrogen-containing groups, which are hydroxyl, mercapto, primary amino or secondary amino groups. To manufacture the film the compositions are coated on the carrier film by a laminar flow process using an extrusion coating hopper. The resulting film has outstanding gloss and beauty and improved mar resistance. Certain embodiments of the new film can be thermoformed, stretched and bonded adhesively to automobile body parts, boats, or household appliances and other substrates as protective and decorative coverings having a basecoat-clearcoat appearance. Others can be applied to such substrates without substantial stretching as toning and styling stripes.
