Abstract

The effects of Photoflo and Tween-20, two surficants were investigated on three different films. Gamma and speed were the criteria investigated. Photoflo was found to have generally little or no effect on the criteria investigated. Tween-20 was found to be effective in increasing the gamma and speed of the films tested. The relationship of gamma and speed change versus concentration level did not follow any recognizeable pattern.
