摘要： A new liquid cleaner composition is provided for the mild and gentle removal of polymeric materials from sufaces without leaving any residues. The said new cleaner composition is an emulsion of the water-in-oil type comprising an aqueous phase finely dispersed in a continuous phase selected from the group consisting of nonflammable, fire-retardant, high-boiling, and fire-retardant and high-boiling organic phases, the volume ratio of the finely dispersed aqueous phase to the continuous organic phase being in the range of from 90:10 to 10:90. The new liquid cleaner composition can contain alcohols, surface-active agents and further useful additives. The new liquid cleaner composition is most preferably used in the process for preparing photopolymerized flexographic relief printing plates as the developer for washing out the non-irradiated and thus non-photopolymerized areas of the imagewise irradiated relief-forming recording layers of the said flexographic relief printing plates.

摘要： 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.

摘要： A novel photosensitive recording element having a dimensionally stable substrate (A), a photopolymerizable relief-forming recording layer (B), which may consist of two or more individual layers (B), and an optically transparent top layer (C) firmly adhering to the surface of (B) is used for the production of a flexographic relief printing plate. Imagewise exposure of the photopolymerizable relief-forming recording layer (B) of the novel photosensitive recording element to actinic light results in a difference between the solubilities of its exposed and unexposed parts, so that its unexposed parts can be washed out (developed) with a solvent. On the other hand, the optically transparent top layer (C) of the novel photosensitive recording element is insoluble or nonswellable in the relevant solvent. The imagewise exposed novel photosensitive recording element can nevertheless be developed in one operation with the aid of an emulsion of the water-in-oil or oil-in-water type. These emulsions are also suitable for developing imagewise exposed photosensitive recording elements whose photopolymerizable relief-forming recording layer (B) consist of two or more individual layers (B) having different solubility properties. In this case too, development is effected in one operation.
