"Laser films are single emulsion films. The emulsion is silver halide sensitized to the red light , which is the inherent colour of lasers used in printers. Therefore it has to be handled under total darkness. These films are for wet chemical processing.

Dry laser films have an emusion consisting of Silver behenate instead of silver halide. Silver behenate is a crystalline long-chain silver carboxylate. The image is formed after exposure to laser and heated to a temperature of 120 degrees celcious.

There is no special composition for so called day light films, except that they are packed in such a way that they can be loaded into a device in daylight, without being exposed to light."
