A peel-apart monochromatic instant film unit including two separate diffusion transfer sheets, namely, a negative or photosensitive in which a latent image is created as a result of exposure and a positive or image-receiving sheet where the positive image is formed. The photosensitive sheet has a carbon containing paper base support which is provided on its one side with a white paper layer, a titanium dioxide containing polyethylene layer and a photosensitive emulsion layer, in that order, and on the opposite side is optionally provided with a transparent polyethylene layer and a backing layer.
