Abstract

A water-resistant support material for light-sensitive materials is disclosed, which is coated on one side or two sides with a polyolefin resin. At least the polyolefin resin of the front-side coating is a copolymer of ethylene and a non-ethylene .alpha.-olefin. This copolymer allows to add to the coating mass a high content in light-reflecting white pigment.
