APPENDIX
1. A method of accelerating image formation during
black and white development of a negative type silver halide
photographic element comprising the steps of:
exposing said negative type silver halide photographic
element to actinic radiation; and
contacting said negative-type silver halide
photographic element during processing with a developer prebath
or a developer bath comprising an accelerator compound of the
formula:
wherein
R is a substituted or unsubstituted alkyl group having
1
from 1 to 28 carbon atoms, a substituted or unsubstituted alkenyl
group having from 1 to 28 carbon atoms, a substituted or
unsubstituted cycloalkyl group having from 3 to 28 carbon atoms,
a substituted or unsubstituted aryl group having from 6 to 33
carbon atoms, an alkyl, cycloalkyl, alkenyl, alkoxyalkyl, aryl,
or phenoxy group, connecting to a substituted or unsubstituted
aryl group, having 6 to 33 carbon atoms, or an alkyl, cycloalkyl,
alkenyl, alkoxyalkyl, aryl, or phenoxy group connecting to a
substituted or unsubstituted heterocyclic ring containing two or
more heteroatoms having 1 to 25 carbon atoms;
R is a substituted or unsubstituted amine group having
2
from 0 to 25 carbon atoms, a substituted or unsubstituted alkyl
group having from 1 to 28 carbon atoms, a substituted or unsub-
stituted alkenyl group having from 1 to 28 carbon atoms, a
substituted or unsubstituted cycloalkyl group from 3 to 28 carbon
