Abstract
Organic volume phase holographic recording medium comprising an .alpha.-diketone in an acrylic polyester polymer is desensitized by exposing the medium to desensitizing light after recording is complete. This inactivates the .alpha.-diketone and prevents damage to the medium during readout.
