Abstract: A pellet aggregate preferably used in forming a film is obtained by a melt-film forming method. A raw material, which is formed of a cellulose acylate and an additive, is placed in a hopper. The pellet raw material is supplied from the hopper to an extruder, melted therein and extruded as a strand in a water vessel to cool the strand. The strand is then fed into a cutting unit. Washing water is supplied from a water supply unit to a cutting section of the cutting unit. The strand is cut into pellets by the cutting section and the generated powder is recovered by a powder separation unit. After the pellets are separated by a pellet/water separation unit, they are fed to a sieve unit to further remove powder by the sieve. The pellets from which the powder is removed is fed to a vessel and stored as a pellet aggregate.

Abstract: A method for producing a conductive film, which comprises: exposing and developing a light-sensitive material comprising a support and thereon an emulsion layer containing a silver salt emulsion to form a metallic silver; and then subjecting the light-sensitive material to a smoothing treatment (such as a calender treatment).
