This film uses a small amount of caustic paste. If any paste appears, avoid contact with skin, eyes and mouth
and keep away from children and animals. If you get some paste on your skin, wipe it off immediately, then
wash with water to avoid an alkali burn. If eye contact occurs, quickly wash the area with plenty of water and
see a doctor. Keep discarded materials away from children, animals, clothing and furniture.

D-Max: The density value for the film’s darkest black.
D-Min: The lowest density value that a film exhibits. In prints, the
whiteness of the brightest highlight, relative to the unprocessed print.
Slope: The positive ratio of the log E increments of the straight line
region of the curve, as determined by the 1/4-3/4 increment method.
The slope of an H&D curve indicates the overall contrast of a film: low
contrast slopes less than 1.10; medium contrast slopes from 1.10 to
0-2 -1
1.70; high contrast slopes greater than 1.70.
