ILOP
General-purpose, high-speed, medium-contrast, integral film for high definition instant color prints. [. . . ] 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. Do not burn battery or allow metal to touch terminals.

Relative Log Exposure
D-Max: The density value for the film's darkest black. 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. [. . . ] Reciprocity failure occurs during very long or very short exposures, requiring the photographer to increase exposure.
