ABSTRACT:
A method of manufacturing a metal matrix in which a supporting plate bearing a photo-resist layer is irradiated patternwise, the irradiated parts are developed and thereby removed, the obtained master disc is provided with a metal peel, which subsequently is removed, whereby after removal of the patternwise irradiated parts of the photoresist layer, the remaining parts are irradiated. The invention also relates to a new intermediate product which comprises a supporting layer, a photoresist layer having an information track and an electrically conductive layer on the photoresist layer, the photoresist layer being a fully irradiated layer.
