Abstract: A security element for securing value documents comprises a first polymer containing a feature substance, which is at least partially surrounded by a second polymer, wherein the first polymer is a hydrophobic, water-insoluble polymer which, at an elevated pH value and at elevated ambient temperature at a treatment duration of less than 60 minutes can be converted into a hydrophilic, water-soluble polymer. The security elements also contains a second polymer, which is a hydrophilic, water-soluble polymer, wherein the elevated pH value is greater than 12 and the elevated ambient temperature is greater than 90° C.

Abstract: A pigment system of different capsule-luminescent pigments have different emission spectra, preferably different color impressions of the luminescence emission, and possess substantially the same chemical stabilities. The capsule-luminescent pigments are based on organic or metalorganic luminescent substances.

Abstract: The invention relates to a pigment particle for security applications, comprising a duromer matrix and a plurality of core particles of a thermoplastic polymer with a feature substance dissolved in the core particles embedded therein, wherein the feature substance is an organic or metalorganic substance. The invention further relates to a method for producing security pigments, for example luminescent printing pigments, by means of incorporation into a duromer matrix of thermoplastic polymer particles in which the luminescent illuminant is present respectively in dissolved form.
