    Abstract: This invention relates to a multi-layer element, suitable for the production of printing plates and relief plates, which comprises (a) a photosensitive layer of a mixture which is soluble and/or dispersible in aromatic hydrocarbon solvents or aliphatic halohydrocarbon solvents and consists essentially of at least one elastomeric polymer as the binder, at least one photopolymerizable, ethylenically unsaturated monomer compatible with the binder, and a photopolymerization initiator which is activated by actinic light, with or without conventional additives, (b) a sheet-like polyester shaped article as the dimensionally stable base for the photosensitive layer (a) and (c) a thin adhesive layer, between the layer (a) and base (b), consisting of a thermally hardened mixture which is insoluble in the aromatic hydrocarbon solvents or aliphatic halohydrocarbon solvents and contains (c1) from 90 to 40% by weight, based on the sum of (c1) and (c2), of à resin which has been hardened and crosslinked with isocyanate, and which has from about 4 to 20% by weight, based on the non-crosslinked and hardenable resin, of free OH groups before hardening and crosslinking with isocyanate, and (c2) from 10 to 60% by weight, based on the sum of (c1) and (c2), of an OH-free polycarbonate which is compatible with the resin (c1) before the latter is hardened and crosslinked. The above defined multi-layer element possesses improved stability in processing and use.

    Abstract: Irreversible optical recording medium is based on a substrate with a texturised surface and a 10-50 nm thick metal or semiconductor coating having an optical absorption of 5-95%. The novelty is that the texture consists of hemispherical structures, which change when irradiated with light. Pref., the hemispherical structures are statistically arranged and consist of a mixt. of raised or indented areas with various diameters between 50 and 200 nm.
