ABSTRACT:
A process for parallel and automated evaluation of the blushing of multiple samples of dispersion films, comprising: providing an illuminated array of spatially separated samples of dispersion films, imaging the array of samples by means of CCD camera at different times and digitizing the images, automatically determining multiple brightness for each sample at different times from the different digitized images for at least a portion of the samples, determining values of a parameter characteristic of the kinetics of the blushing from the different brightnesses, and comparing the values of the characteristic parameter for individual samples.
