1. A method for the manufacture of a prophylactic article from a diene rubber or carboxylated diene rubber, according to which a layer of a diene latex or carboxylated diene latex is applied on a former and the diene latex or carboxylated diene latex is exclusively cross-linked with a cross-linking agent comprising organic molecules,
wherein the cross-linking agent is immobilized on inorganic and/or organic particles with formation of modified particles, and the modified particles are added to the diene latex or carboxylated diene latex,
wherein exclusively the modified particles are used as cross-linking agents,
wherein the prophylactic article produced has incorporated the modified particles modified with the cross-linking agent comprising the organic molecules,
wherein silicate-based particles are used as the inorganic particles, and
wherein the silicate-based particles are selected from a group consisting of silicates with multivalent cations, zeolites, as well as mixtures thereof.
