Abstract

Abstract: Internally sensitized core-shell emulsions were prepared and it was shown that smallsilver specks formed on the surface of the core emulsion behave like hole traps.Whenthese emulsions were mixed with surface-sensitized emulsions, the sensitivity,contrast and maximum density increased.In this paper,the influence of some factors on the preparation process are studied and the function of the internally sensitized emulsions in the systermare discussed.

Key words: core-shell emulsion, sensitization, hole trap
