<p>The present invention provides a process for the production of reagent films in which an aqueous synthetic resin dispersion which contains the usual adjuvants and reagents is coated on to a solid substrate or on to a thin fabric in a thin layer and dried, wherein to the crude film mass used for the coating there are added 0.5 to 5% by weight of a scleroprotein hydrolysate with a molecular weight of from 5000 to 50,000 and 0.5 to 10% by weight of a higher alcohol containing 5 to 10 carbon atoms.</p>
