The PZ 600 Silver Shade UV+ is a black and white instant film. It is manufactured by Impossible in the Netherlands for Polaroid's old Image/Spectra cameras.
The PZ 600 Silver Shade UV+ is a further development of the PZ 600 Silver Shade. The UV+ device is said to provide improved image stability and better B&W tones. Depending on the temperature during development, the color tone of the later black and white image changes. So at about 20°C you get sharp black and white tones and at about 23°C more a sepia look.
One pack of the instant film is enough for 8 pictures.
Update
The current black and white film for the Image/Spectra format from The Impossible Project is the Polaroid Originals B&W Film for Image & Spectra*.
