1. A process for parallel and automated evaluation of the blushing of n samples of dispersion films, which comprises (a) providing an illuminated array of n spatially separated samples of the dispersion films, (b) imaging the array of n samples by means of a CCD camera at m+1 different times T 0 to t m and digitizing the images, (c) automatically determining a plurality of brightnesses B(k, t i ) for each sample at different times T i selected from t 0 to t m from the m+1 different digitized images for at least a portion of the n samples, where B(k, t i ) is the brightness of the kth of n samples at the respective time t i and is a measure for the blushing of this sample at this time, (d) determining a value P(k) of a parameter which is characteristic of the kinetics of the blushing from the different brightnesses B(k, t i ) for each sample for at least a portion of the n samples, where P(k) is the value of the characteristic parameter for the kth of the n samples.
