ABSTRACT:
A novel, improved continuous process for the production of a photosensitive recording element is described, whose photopolymerizable recording layer (A) consists of two or more individual strata (a.sub.n) lying one on top of the other and firmly bonded to one another. The individual strata (a.sub.n) may be of the same or roughly the same composition or of different compositions. In the novel, improved continuous process, the mixtures (a.sub.n) used for the production of the individual strate (a.sub.n) are prepared separately from one another and melted and, as separate molten material streams (a.sub.n), are combined even before entering the nip of a calender, without the said streams mixing as a result of turbulence. During, before or directly after they have been combined, the molten material streams (a.sub.n) are formed into molten sheet-like structures (a.sub.n) lying one on top of the other, without the said streams mixing as a result of turbulence. Thereafter, the molten sheet-like structures (a.sub.n) lying one on top of the other are introduced into the calender nip, one or both of the two outer molten sheet-like structures (a.sub.n) in contact with the calender rollers forming a rotating melt bead or rotating bank. In the calender nip itself, the said sheet-like structures (a.sub.n) are then calendered with production of the photopolymerizable recording layer (A) consisting of individual strata (a.sub.n) lying one on top of the other and firmly bonded to one another.
