ABSTRACT:
This invention provides composition and method to overcome the very high viscosity of prior small-particle dispersions when admixed with gelatin in aqueous solution for coating a photographic film element.
The invention is generally accomplished by the utilization of a second surfactant in the melt formulated by the admixture of the small-particle dispersion and the gelatin solution. The surfactants of this invention, that is, utilized to control the theology of such said melts, have the following general structure: ##STR1## wherein n=5 to 20 and
