Definitions

  • the anionic acidic polymers used in conjunction with the dispersed polythiophene polymer preferably have a content of anionic groups of more than 2% by weight with respect to said polymer compounds to ensure sufficient stability of the dispersion.
  • Suitable acidic polymers or corresponding salts have been described e.g. in DE-A's 25 41 230, 25 41 274 and 28 35 856, in EP-A's 0 014 921 0 069 671 and 0 130 115, and in US-A's 4,147,550; 4,388,403 and 5,006,451.
  • the polymeric polyanion compounds may consist of straight-chain, branched chain or cross-linked polymers.
  • the support is a polyethylene terephthalate layer provided with subbing layers at both sides, the subbing layer at the light-sensitive comprising the compound(s) providing permanent antistatic properties (electronic conductivity).
  • a black and white silver halide motion picture sound recording film may be used, said film comprising a support bearing at least one silver halide emulsion layer, wherein said film is spectrally sensitized both above and below 600 nm as disclosed in US-A 5,955,255, thus being panchromatically sensitized as in GB 449,546 and corresponding FR 784,027.
  • Such film may be used for recording multiple optical soundtracks by exposing said film with a first source of radiation having a peak wavelength of less than or equal to 600 nm, recording a second digital soundtrack by exposing said film with a second source of radiation having a peak wavelength of greater than 600 nm, and processing said exposed film to form first and second digital soundtrack silver images.
  • Drying was performed during 1 minute at 120°C.
  • Both materials were coated with an outermost backing layer comprising acid as an antistatic agent: polystyrene sulfonic acid in an amount of 35 mg/m 2 ; as a binder: a sodium salt latex copolymer of vinyl acetate/maleic acid in an amount of 20 mg/m 2 ; and as a lubricant polyethylene wax in an amount of 12.5 mg/m 2 .
  • acid as an antistatic agent: polystyrene sulfonic acid in an amount of 35 mg/m 2 ; as a binder: a sodium salt latex copolymer of vinyl acetate/maleic acid in an amount of 20 mg/m 2 ; and as a lubricant polyethylene wax in an amount of 12.5 mg/m 2 .
