    摘要: An aqueous two-component coating agent whose binder consists essentially of a combination of a) a polyol component present dissolved and/or dispersed in water comprising a1) at least one water-dilutable polymerisation resin or polycondensation resin with a molecular weight Mn of over 500 possessing hydroxyl groups and a2) a reactive diluent consisting of at least one water-soluble compound with a molecular weight Mn of under 500 capable of reacting with isocyanate groups and b) a polyisocyanate component with a viscosity at 23.degree. C. of from 50 to 10 000 mPa present emulsified in the aqueous solution or dispersion, a method for producing such coating agents wherein the said polyisocyanate component is emulsified in the said aqueous solution or dispersion with the optional incorporation of auxiliary substances and additives in the system prior to adding the polyisocyanate, and the use of the coating agents for the production of air-drying and/or heat-drying coatings.
