Abstract: Method and device for producing a printed and embossed multi-ply web (3) of tissue paper or nonwoven having a good visual appearance. A first web-shaped material (1) is embossed in a nip (6) between a first embossing roll (4) and a counter roll (5), thereby creating a set of embossments. A first ink with a first colour is applied to a first subset of the set of embossments of the first web-shaped material while the material still resides on the first embossing roll. Thereafter an adhesive is applied to a second subset of the set of embossments of the first web-shaped material (1) while the material still resides on the first embossing roll (4). After that, the first web-shaped material is combined with a second web-shaped material (2) to form a multi-ply web (3). There is also provided a printed and embossed multi-ply web (3).

Abstract: A magnetic recording medium consisting of a flexible layer support and a magnetic layer consisting predominantly of magnetic particles finely divided in a binder and nonmagnetic additives applied to the layer support is obtained with improved orientation of the magnetic pigments by adding a dispersion stabilizing component to the magnetic dispersion at a uniform rate over the whole period of dispersion. Highly purified lecithin or a mixed ester of a polyethoxy phosphate ester or ethylene diaminodistearate, a polyurethane resin containing sulphonate groups or a vinyl chloride/vinyl alcohol copolymer is preferred as stabilizing additive.
