Abstract: A separation membrane suitably for water separation. The membrane includes a porous substrate layer and an active layer arranged over at least a part of the substrate layer. The active layer includes a lamellar structure comprising at least two layers of treated two-dimensional material.

Abstract: A method and apparatus for imaging, cutting and applying a linerless label substrate 2. The substrate 2 is transported to an imaging area and is selectively illuminated by a suitable laser to form an image. By determining the position of the edge of the image, further laser illumination is used to cut the label substrate thereby providing a single label for application to an object. In this manner, the method of the present invention provides all the benefits of a linerless labelling system plus enables flexibility in printing labels of different sizes.

Abstract: A substrate coated with a markable ink formulation, comprising AOM. Further, the substrate is covered by a thermoplastic polymer layer, such that the ink formulation is situated between the substrate and the thermoplastic polymer layer and/or in the thermoplastic polymer layer.

Abstract: A substrate coated with a markable ink formulation, comprising a thermo activated acid generator (TAG) and a halochromic leuco dye. The thermo activated acid generator is selected form the group consisting of: an amine salt of an organic metal compound comprising boron or silicone and amine neutralized polyalkylnaphthalene polysulphonic acid derivatives. Further, the substrate is covered by a thermoplastic polymer layer, such that the ink formulation is situated between the substrate and the thermoplastic polymer layer and/or in the thermoplastic polymer layer.

Abstract: An ink formulation having a marking component and a reduced indium tin oxide (r-ITO) is disclosed. The r-ITO in powder form exhibits a lightness (L*), according to the 1976 CIE (L*, a*, b*) space, of not more than 50.

Abstract: A substrate marking apparatus for use in combination with a substrate comprising a multi-color change diacetylene compound is disclosed. The substrate marking apparatus comprises: at least two radiation sources operable to emit radiation of different wavelengths, optical transformation elements and a control system. The control system takes digital file information and converts this to a set of emission instructions for the radiation sources. The radiation sources are then applied to the substrate in sequence and intensity determined by the control system such that the substrate is activated to change from a colorless state to any one of a range of multiple permanent colors.
