The invention relates to aqueous primary dispersions and coating matters containing dispersed and or emulsified, solid and or liquid polymer particles and or dispersed solid core shell particles having a particle diameter le; 500 nm. The inventive dispersions and coating matters can be produced by means of radical micro or miniemulsion polymerisation of at least one olefinically unsaturated monomer (A) in the presence of at least one hydrophobe cross linking agent for the (co)polymer resulting from the monomer or the monomers (A). The invention also relates to a method for producing same and to the use thereof. La invencion se refiere a dispersiones acuosas primarias y materias de revestimiento que contienen particulas polimericas solidas y/o liquidas dispersadas y/o emulsificadas y/o particulas de nucleo-envoltura solidas dispersadas que tienen un diametro de particula inferior o igual a 500 nm. Las dispersiones y materias de revestimiento de la presente invencion pueden ser producidas por medio de polimerizacion en microemulsion o miniemulsion de radicales de por lo menos un monomero olefinicamente insaturado (A) en presencia de por lo menos un agente de reticulacion hidrofobico para el (co)polimero que resulta del monomero o de los monomeros (i_i). La invencion se refiere tambien a un metodo para la produccion y el uso de las mismas.
