ABSTRACT:
An internal latent image silver halide emulsion is disclosed comprising core/shell silver halide particles having a chemically sensitized surface which are composed of a core of silver halide doped with metal ions and/or subjected to chemical sensitization and a shell which covers said core as far as to do at least the sensitive sites of said core and a binder, wherein said silver halide emulsions contain a polymer containing a repeating unit represented by the following general formula (I) in an amount of 2 mg to 1000 mg per mole of silver as the weight of said repeating units in said polymer: ##STR1## wherein R.sup.1 represents a hydrogen atom or an alkyl group and Q represents a group selected from the group consisting of the following (1)-(4): ##STR2## wherein q represents an integer of 2 to 4, ##STR3## wherein R.sup.2 and R.sup.3 each represents a hydrogen atom or an alkyl group, ##STR4## wherein Z.sup.1 represents an atomic group necessary to complete a lactam ring, an oxazolidone ring or a pyridone ring, and A represents a single bond, ##STR5## wherein B represents --O-- or ##STR6## wherein R.sup.4 represents a hydrogen atom or an alkyl group, and l represents an integer of 1 to 6,
and ##STR7## wherein A has the same meaning as in (3), D represents a single bond, --O-- or ##STR8## and m and n each represents an integer of 1 to 6 which satisfies the relationship m+n=4 to 7, wherein R.sup.5 represents a hydrogen atom, an alkyl group or ##STR9## wherein R.sup.6 represents an alkyl group. The internal latent image silver halide emulsions have good stability with the passage of time.
