An aluminum flake pigment containing aluminum flakes as basic particles, said aluminum flakes having an average particle diameter in the range of 3 to 20 \u03bcm and an average value of minimum diametermaximum diameter of at least 0. The composition contains: an isocyanate component comprising a difunctional isocyanate-terminated prepolymer having polymerized residues of at least one difunctional aromatic isocyanate and at least one difunctional polymer of ethylene oxide, propylene oxide or a combination thereof; a polyol component comprising a triglyceride having hydroxyl functional groups; and an adhesion promoter. Upon pressing the scan and transmit button, a document is scanned with the scan settings associated therewith and the acquired document data is transmitted to the transmission destination associated with the scan and transmit button. Intermediate adhesion layers or adhesion treatments can also be employed. The biological preconcentrator can be fabricated with semiconductor materials and technologies. This angling is calculated from the trajectory at the individual positions in the prescribed perspective such that a maximum segment of the trajectory is contained in each of the MR tomograms.
