ABSTRACT:
Alkylenglycol aliphatic diesters are water-immiscible high-boiling organic solvents useful for dispersing hydrophobic photographic additives in hydrophilic colloid compositions which are incorporated into the composing layers of light-sensitive silver halide photographic materials.
In particular, said alkylenglycol aliphatic diesters correspond to general formula ##STR1## wherein R.sub.1 and R.sub.2, the same or different, each represents an alkyl group having 1 to 15 carbon atoms, Q represents an acylic hydrocarbon divalent group having 1 to 10 carbon atoms, m represents 0 or 1 and the total number of carbon atoms represented in R.sub.1 +R.sub.2 is at least 6.
