    Abstract: New active agent formulations contain active agent(s) (A); random radical copolymer(s) (B), derived from sulfoalkyl (meth)acrylate or N-sulfoalkyl-(meth)acrylamide monomer(s) (I) (and/or their salts), (meth)acrylate ester or N-substituted (meth)acrylamide monomer(s) (II) and optionally further monomers; and optionally further additives (C). New active agent formulations contain active agent(s) (A); random radical copolymer(s) (B), derived from olefinically unsaturated sulfonic acid(s) of formula (I) (and/or their salts), monomer(s) of formula H 2C=C(R 4>)-CO-YR 6> (II) and optionally further monomers; and optionally further additives (C). n : 0-10; X, Y : O or NR 5>; R 1>, R 4>H or Me; R 2>, R 3>H or 1-6C alkyl; R 5>, R 6>H, alkyl, aryl, alkylaryl, alkoxyalkyl, aryloxyalkyl, alkoxyaryl, hydroxyalkyl, (di)alkylaminoalkyl, (di)arylaminoalkyl, alkylarylaminoalkyl or alkylarylaminoaryl (where aryl groups are optionally substituted). Independent claims are included for: (1) the preparation of aqueous dispersions, by contacting the formulations with aqueous systems (optionally in presence of additives) and dispersion conventionally; (2) the preparation of the formulations, by dissolving (A) - (C) and optionally further additives in an organic solvent (or dissolving the components separately in organic solvents then mixing the solutions), then conventionally removing the solvent; and (3) an alternative preparation of the formulations, by forming an aqueous solution of (B); dissolving (A), (C) (if present) and optionally further additives in water-miscible organic solvent(s); mixing the solutions; applying energy to form a dispersion; and conventionally removing the solvent.

    Abstract: Coded micro-particles for marking materials are obtained by polymerisation of unsaturated monomers in presence of dyes and/or doped nano-particles, and/or by agglomeration of at least two groups of microparticles which differ in their absorption, emission and/or scattering of electromagnetic radiation, to give aggregates with a particle diameter of 300 nm to 500 microns. A method for marking materials with coded micro-particles (I), in which (I) are obtained by (i) reversed water-in-oil suspension polymerisation of water-soluble mono-unsaturated monomer(s) (IIa) in presence of poly-unsaturated comonomer(s) (III) using doped nano-particles (IV) as the suspension medium, (ii) emulsion polymerisation of water-insoluble mono-unsaturated monomers (IIb) with 0-10 wt% (III) using (IV) as emulsifier for stabilising the disperse phase, (iii) polymerisation of (II) with a copolymerisable dye containing an ethylenic double bond, optionally followed by agglomeration of the resulting particles, or (iv) agglomeration of at least two groups of micro-particles which differ in their absorption, emission and/or scattering of electromagnetic radiation, to give aggregates with an average particle diameter of 300 nm to 500 microns. An independent claim is also included for materials containing coded (I) for the purposes of marking.
