The need for light filters to attenuate flashes in plastic scintillators arose in designing apparatus for measurement of the charge composition of primary cosmic rays. Eight photomultipliers, each of which required a light filter, were arranged horizontally over a length of 50 cm in each of 10 rows of an ionization calorimeter. It was required that the absorption coefficients of all 80 light filters differ by not more than 3% for light attenuation by a factor of approx. 1000. Light filters from KN-3 motion-picture film of the Kazan Chemical Plant are described that attenuate scintillation flashes from cosmic particles by a factor of 660 +/- 13. The stability of the light-absorption coefficients of the films for 15 months is checked.
