Abstract
Abstract A recording medium having two outer sheets (1, 3) forming a pocket, and an extractable intermediate sheet (5) lying in between, the latter producing a recording contrast in a recording action and being removed from the pocket after noting, there further being provided between the outer sheets a sticky area (17), which does not stick to the intermediate sheet but to the opposite sides of the outer sheets (1 and 3), in order to prevent an impairment of the noting by the sticky area (17) provided, the sticky area (17) is provided on one side with respect to the intermediate sheet (5) and the operative connection effecting the recording contrast is arranged on the other side of the intermediate sheet (5) between the latter and the outer sheet (1) neighboring there.
