<p>A plastics film is provided which is filled with a filler, has diffuse reflective properties and is coated with a coating containing a photosensitive organic compound. The film is useful in the production of information storage devices by combining it with a perforated mask disposed on the side of the film which bears the coating. The film is formed from cellulose, cellulose acetate or polyamide or poly (ethylene terephthalate). The filler is preferably a white pigment, eg titania or barium sulfate. The photosensitive compound is preferably photochromic eg a fulgide.</p> |
