The invention relates to a water-based coating composition comprising:

Water-based two-component coating compositions

Polyurethaneurea resins containing at least one group of the formula (I)&#x2014;NH(CO)XORO(CO)CHRCHN[CHSi(OR)](CO)NH&#x2014;&#x2003;&#x2003;(I)and/or at least one group of the formula (II){&#x2014;NH(CO)XO}{CH&#x2550;CR(CO)O}R{O(CO)CHRCHN[CHSi(OR)](CO)NH&#x2014;}&#x2003;&#x2003;(II)wherein

Polyurethaneurea resins with trialkoxysilane groups and processes for the production thereof

A process for the production of polyurethane di(meth)acrylates in which a diisocyanate component, a diol component and hydroxy-C2&#x2013;C4-alkyl (meth)acrylate in the molar ratio x:(x&#x2212;1):2 are reacted without solvent and without subsequent purification operations, wherein x means any desired value from 2 to 5, wherein 50 to 80 mol % of the diisocyanate component is formed by 1,6-hexane diisocyanate, and 20 to 50 mol % by one or two diisocyanates, each forming at least 10 mol % of the diisocyanate component and being selected from the group consisting of toluylene diisocyanate, diphenylmethane diisocyanate, dicyclohexylmethane diisocyanate, isophorone diisocyanate, trimethylhexane diisocyanate, cyclohexane diisocyanate, cyclohexanedimethylene diisocyanate and tetramethylenexylylene diisocyanate, wherein the mol % of the respective diisocyanates add up to 100 mol %, wherein the diol component comprises no more than four different diols, and 20 to 100 mol % of the diol component is formed by at least one linear aliphatic alpha,omega-C2&#x2013;C12-diol, and 0 to 80 mol % by at least one (cyclo)aliphatic diol that is different from linear aliphatic alpha,omega-C2&#x2013;C12-diols, wherein each diol of the diol component forms at least 10 mol % within the diol component, and wherein the mol % of the respective diols add up to 100 mol %.
