    摘要： Hydrophobic substances, particularly hydrophobic additive for photographic layers such as couplers may be dispersed in an aqueous medium in a two--or more--stage process using an oil-former. In a main dispersion stage the total quantity of the hydrophobic substance is dispersed in the aqueous medium without oil-former or with only part of the total quantity of oil-former. The residual portion of oil-former is dispersed in the aqueous medium without hydrophobic substance in at least one further dispersion stage preceding or following the main dispersion stage. The oil-former used is preferably a compound or a mixture of compounds selected from triaryl phosphates, dialkyl phthalates, monoesters of .alpha.-substituted succinic acid or of hydrogenated phthalic acids and aliphatic or cycloaliphatic alcohols of at least 10 carbon atoms. The process yields dispersions of improved stability of digestion.

    摘要： In order to be able to cast additional layers on auxiliary layers of photographic materials immediately after the latter have been cast without encountering any difficulties as regards uniformity of the cast layer and wet adherence due to incomplete conversion of the gelatine from the sol to the gel form, the auxiliary layer must contain an effective quantity of at least one compound obtained by the reaction of trihydric to hexahydric alcohols with propylene oxide.
