Abstract

The present invention refers to a process for preparing a dispersion which comprises codispersing in an aqueous medium a sucrose derivative represented by the following general formula (1), wherein substituents X.sub.1 to X.sub.8, being the same or different, are represented by a hydrogen atom, an alkyl group or an acyl group, with the proviso that at least four of the X.sub.1 to X.sub.8 substituents are different from hydrogen and that the total sum of the carbon atoms of X.sub.1 to X.sub.8 substituents is at least sixteen; and a photographic compound represented by the following general formula (2), wherein R and R.sub.1 each independently represent a hydrogen atom, an alkyl group, an alkylene group, a heterocyclic group or an aryl group; R.sub.2, R.sub.3 and R.sub.4 each independently represent a hydrogen atom, an alkyl group, an aryl group and R.sub.3 and R.sub.4 may be combined to form a 6-membered ring. ##STR1## The present invention also refers to a photographic dispersion comprising a sucrose derivative represented by previous general formula (1) and a photographic compound represented by previous general formula (2) dispersed in an aqueous medium and to a photographic element comprising a film support base having coated on one side thereof at least one hydrophilic colloid emulsion layer comprising said photographic dispersion. The process of the present invention allows photographic dispersions to display a narrow drop size distribution curve even when stored for a long period of time (30 days) in cold room.
