THE KINETICS OF ADSORPTION IN THE PROCESS OF FILM COATING

Many technologies of coating film bases are often applicable in the presence of surface active agents. The purpose of this paper is to present basic results on the time depending action of surfactant used as wetting agent, stabilizer in three phase contact zones and to the damping of surface perturbations, respectively. Information recording materials on the basis of silver halides contain in general gelatin. Gelatin itself shows surface active properties. Therefore, we have to take in our consideration three kinetics of adsorption: Pure surfactant, pure gelatin and the complex of gelatin with surfactant, respectively. One has to notice that this general formulation is still difficult to deal with. Only the mass transfer of simple components leads to a first approximation under the conditions of real now properties. However, we will focus our attention to the problem of the mixed adsorption.
