Coating material and its use for producing filler coats and stone impact protection primers

   
   

The use of a copolymer (A) preparable by free-radical polymerization of a) at least one olefinically unsaturated monomer and b) at least one olefinically unsaturated monomer different than the olefinically unsaturated monomer (a) and of the general formula I R.sup.1 R.sup.2 C.dbd.CR.sup.3 R.sup.4 (I), in which the radicals R.sup.1, R.sup.2, R.sup.3 and R.sup.4 each independently of one another are hydrogen atoms or substituted or unsubstituted alkyl, cycloalkyl, alkylcycloalkyl, cycloalkylalkyl, aryl, alkylaryl, cycloalkylaryl, arylalkyl or arylcycloalkyl radicals, with the proviso that at least two of the variables R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are substituted or unsubstituted aryl, arylalkyl or arylcycloalkyl radicals, especially substituted or unsubstituted aryl radicals; in an aqueous medium, in a coating material used to produce surfacer coats and antistonechip primer coats.

Польза сополимера (A) preparable свободно-radikal6no1 полимерностью a) по крайней мере одного olefinically unsaturated мономера и b) по крайней мере один olefinically unsaturated мономер по-разному чем olefinically unsaturated мономер (a) и вообще формулы iego R.sup.1 R.sup.2 C.dbd.CR.sup.3 R.sup.4 (i), в которой радикалы R.sup.1, R.sup.2, R.sup.3 и R.sup.4 каждое независимо одного другое будут атомами водопода или замененными или unsubstituted радикалами алкила, cycloalkyl, alkylcycloalkyl, cycloalkylalkyl, арила, alkylaryl, cycloalkylaryl, arylalkyl или arylcycloalkyl, with the proviso that по крайней мере заменены 2 из перемеююых R.sup.1, R.sup.2, R.sup.3 и R.sup.4 или unsubstituted радикалы арила, arylalkyl или arylcycloalkyl, специально заменены или unsubstituted ариловые радикалы; в водяном средстве, в покрывая материале используемом для того чтобы произвести пальто surfacer и пальто праймера antistonechip.
