摘要： A positive-working radiation-sensitive mixture is described that contains (a) a radiation-sensitive compound which forms a strong acid under the action of actinic radiation, (b) a compound with at least one C--O--C bond cleavable by acid, (c) a binder which is insoluble in water but soluble in aqueous-alkaline solutions, and (d) a polymethine dye. The polymethine dyes used are hemioxonol dyes or symmetrical cyanine dyes. In the light-sensitive mixture, these dyes effect high sensitization and high image sharpness contrast which, in addition, is substantially irreversible.

摘要： A device for cathodic corrosion protection such as for hot water tanks having a passive anticorrosive layer on the inner wall of the tank. The cathodic corrosion protection employs the use of an external current anode. The device includes a holder which bears the external current anode and a reference electrode. The holder is adapted to be inserted into a single opening in the tank wall. A potentiostat employs the external current anode and reference electrode so as to establish a predetermined potential between reference electrode and the tank by regulating the current flowing through the external current anode to the tank. This provides the desired corrosion protection. Two embodiments of the device are described.

摘要： This invention relates to an improvement in a light-sensitive copying material, the copying layer of which comprises a water-soluble, curable binder and a diazonium salt polycondensation product of recurring units of the general types (A-N.sub.2 X) and (B) which are linked to one another by intermediate members which have two bonds and are derived from a carbonyl compound capable of undergoing a condensation reaction, wherein A is the radical of a compound which contains at least two isocyclic or heterocyclic aromatic rings and is able to undergo a condensation reaction, at least at one point in the molecule, with formaldehyde in an acid medium, B is the radical of a compound which is free of diazonium groups and is able to undergo a condensation reaction, at least at one point in the molecule, with formaldehyde in an acid medium, and X is the anion of an acid which forms a water-soluble salt with the condensation product, the improvement being that fish glue is the water-soluble, curable binder. The invention also relates to a process for the production of colored relief images.
