PREPARATION OF A MULTICOAT COATING, WATER-THINNABLE PAINT, PREPARATION OF CROSSLINKED POLYMERIC MICROPARTICLES AND CROSSLINKED POLYMERIC MICROPARTICLES

摘要

The invention relates to a process for the preparation of a multicoat coating, in which process a pigmented basecoat is used which comprises crosslinked polymeric microparticles obtainable by emulsion polymerization. In this process the crosslinked polymeric microparticles comprised in the basecoat are obtainable by using 0.5 to 2.4% by weight of allyl methacrylate or 1.5 to 8.0% by weight of ethylene glycol di(meth)acrylate or 1.5 to 8.0% by weight of butanediol di(meth)acrylate or 1.5 to 10.0% by weight of hexanediol di(meth)acrylate or 0.5 to 6.0% by weight of divinylbenzene, the weight percentages referring to the total amount of the monomer used.
