Light-sensitive silver halide photographic materials and process for incorporating hydrophobic photographic additives into hydrophilic colloid compositions.

摘要

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 correpond to general formula wherein R1 and R2, 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 R1+R2 is at least 6.
