Abstract
The present invention provides a method for preparing an aluminium foil comprising the steps of roughening an aluminium foil and subsequently anodizing said aluminium foil characterized in that after said anodization said aluminium foil is cleaned using an aqueous bicarbonate containing solution. The present invention further provides a mono-sheet silver salt diffusion transfer material having as a support the alumium foil obtainable from the above defined method. The step of cleaning in the bicarbonate containing solution improves the adhesion of an image receiving layer containing physical development nuclei to the aluminum foil as revealed from the increased amount of silver precipitated in the image receiving layer when the aluminum foil provided with an image receiving layer is used in a diffusion transfer reversal (DTR) process.
