  • Patent number: 4796823
    Abstract: A spool for a photographic film comprising 50 to 99.8 wt. % of polystyrene resin, 0.05 to 2.2 wt. % of dimethylpolysiloxane and/or modified dimethylpolysiloxane of which a part of methyl groups are substituted by carboxyalkyl groups, 0.5 to 6 wt. % of rubber and 0.05 to 3 wt. % of carbon black having a pH of 5 to 9 and a mean particle size of 10 to 120 m.mu., and the outer surface of the flange of the spool is made rough so that the reflectance of the incident light at an incident angle of 75 degrees is less than 40% in the direction of regular reflection at an angle of 75 degrees.Static frictional coefficient of this spool against metal is small, and thereby photographic film can be drawn out of a photographic film cartridge smoothly to the last. Breakage of the perforations of photographic film does not occur. The outer surface of the flange of the spool is not glossy and its reflectance is low.
