For the seamless and firm joining of the end and/or lateral areas of thermoplastically processible photosensitive layers, the end and/or lateral areas of one or more solvent-free and unsupported thermoplastically processible photosensitive layers are overlapped avoiding bubbles and with displacement of the air between the end and/or lateral areas, the total layer material is then heated under pressure and with joining of the overlapping end and/or lateral areas, and the resulting continuously joined photosensitive layer is then aftertreated and smoothed with shaping to exact size.
