The present invention is directed to a radically curable chemical composition in form of a resin for the production of materials having an intrinsic antimicrobial effect, to the applications of these materials, to a method for the preparation of these resins and materials, and to the use of an amino-functionalized styrene derivative as a reactive diluent. The cross-linked plastic materials formed after curing have an intrinsic antimicrobial effect without the use of additional biocides.
