<p>The waterproof base for light-sensitive materials is coated on one or both sides with polyolefin resin, at least the polyolefin resin of the front coating containing a copolymer of ethylene and another alpha -olefin. This copolymer makes it possible to add a high proportion of light-reflecting white pigment to the coating composition.</p> |
