A method for detecting amorphous and/or crystalline structures of phosphate and/or sulphate salts on or within a substrate involves providing an LWIR imaging system with an infrared light emitting source (A) configured to emit infrared light over the range of 8 to 14 micrometers, an LWIR detecting device (B) configured to detect the intensity of electromagnetic radiation scattered, emitted, and/or reflected by the substrate, and control circuitry for the LWIR detecting device. The method further comprises providing the substrate, irradiating it with the infrared light emitting source, acquiring a stream of temporally consecutive images using the LWIR detecting device, and selecting, based on processing the acquired stream of images with the control circuitry, at least one focused image where the amorphous and/or crystalline structures of phosphate and/or sulphate salts are substantially in focus of the LWIR detecting device.

Method and apparatus for detecting an amorphous and/or crystalline structure of phosphate and/or sulphate salts on the surface of a substrate or within a substrate

The present invention refers to method for detecting phosphate and/or sulphate salts on the surface of a substrate or within a substrate, use of a LWIR detecting device for detecting the intensity of electromagnetic radiation scattered and/or emitted reflection by phosphate and/or sulphate salts being present on and/or in a substrate, use of a substrate comprising phosphate and/or sulphate salts for providing information via electromagnetic radiation scattering and/or emission as well as a LWIR imaging system for detecting phosphate and/or sulphate salts on and/or within a substrate.

Method for detecting phosphate and/or sulphate salts on the surface of a substrate or within a substrate, use of a LWIR detecting device and a LWIR imaging system

The present invention relates to a method of tagging a substrate with a covert, spectroscopically detectable security feature, wherein a liquid treatment composition comprising at least one acid is deposited onto a substrate, which comprises at least one external surface comprising a salifiable alkaline or alkaline earth compound.

Methods for verifying the authenticity of products

The present invention relates to a method for producing water-insoluble quantum dot patterns on and/or within a substrate. The method comprises a step of depositing a deliquescent salt, quantum dots and an acid or salt thereof onto at least one surface region of a substrate such that the deliquescent salt, the quantum dots and the acid or salt thereof are at least partially contacted to form said at least one water-insoluble pattern.

Method for producing water-insoluble quantum dot patterns

The present invention relates to method of manufacturing a tamper-proof medium for thermal printing, wherein a liquid treatment composition comprising at least one acid is deposited on a substrate which comprises a thermochromic coating layer comprising at least one halochromic leuco dye.
