Abstract: The invention relates to an aqueous solution containing aluminum ions, characterized in that the solution contains aluminum ions in a proportion of 0.5-15% (converted, if necessary, to Al3+) based on the total mass of the solution, as well as anions of lactic acid (lactate ions) and of phosphoric acid (phosphate ions), and has the theoretical composition Al3+A(C3H5O3?)x.ASM?y.A(H2PO4?)z.A(OH)?(3A-x.A-M.y.A-z.A), wherein S is the anion of an acid with the charge M, x is a value in the range of 0.5-2.8, y is a value in the range of 0-1.5, and z is a value in the range of 0.01-1.5.

Abstract: A device for printing, severing and applying self-adhesive labels, wherein the device operates with a label material without a carrier strip. The label material has a printable layer, a carrier layer and a heat-sealable adhesive layer. The device has an applicator, by way of which the label is applied to an object to be labelled. The applicator can be moved up to the object to be labelled by way of a handling device, and the handling device is constructed in accordance with the principle of an open kinematic chain and has at least one translational kinematic axis and/or at least one rotational kinematic axis. The applicator can be heated by way of a heating device which operates in accordance with an electrical operating principle.
