    Abstract: The invention relates to a method for improving the colour brilliance and the stability of a colour polymer system which consists of a matrix and discrete polymer particles distributed in the matrix according to a defined space lattice structure, and is obtained by filming an emulsion polymer having a core/shell structure. The inventive method is characterised in that the emulsion polymer can be obtained by polymerisation of monomers in at least one first step (monomers of the core), further polymerisation of monomers in at least one other, second step (transition step), and final polymerisation of monomers in a third step (monomers of the shell). In relation to the percentual composition of the monomer mixture of the three steps, a maximum 30 wt. % of the monomers of the first step correspond to those of the third step and at least 5 wt. % of the monomers of the second step respectively correspond to those of the first and the third step. A maximum 60 wt. % of the monomers of the second step are monomers from either the first or the third step.

    Abstract: The invention relates to an amplifying medium for solid-state dye lasers and a solid-state dye laser provided with said amplifying medium. Said amplifying medium comprises an essentially solid active medium, containing at least one sort of particles which can be activated and which can be stimulated to emit laser light of a particular wavelength and optical feedback means which define a resonator for the laser light. The feedback means comprises an essentially solid feedback medium which has a periodic structure. The amplifying medium is characterised in that the feedback medium is a polymeric dispersion film with a crystalline structure which particularly comprises core/shell particles which may be coated.
