Abstract
The duration of use of spectrally sensitized pigment bonding agent layers which are to be used a number of times is substantially increased by performing floodlighting, after the development and/or transfer and prior to the recharging, with a light which is suitable per se for the image formation, but which is substantially not absorbed by the dye.
