Abstract
In An earlier paper on this subject<sup>1</sup> the effect of scratches on the strength of film support, not coated with emulsion or processed, was discussed. It was concluded from the measurements that the “principal effect of a scratch is due to its depth” reducing the effective thickness, and “the idea sometimes expressed that the mechanical strength of such materials as support and similar plastics is greatly dependent upon superficial scratches, and a surface skin does not hold for motion picture film support.” In the discussion the point was raised whether the age of the film and its brittleness would not change the matter, so that scratches would have relatively more effect. A further study has now been made on processed film brought to equilibrium with an atmosphere of definite temperature and humidity.
