The present invention relates to a water-based coating composition comprising (a) at least one resin, (b) at least one coalescent agent consisting of a compound having general formula (I) R1 (OR2) nOCOO (R3O) mR4 wherein R1 and R4, independently of each other, are a linear or branched alkyl group, having from 1 to 6 carbon atoms, preferably from 1 to 4; R2 is a linear or branched alkyl group, having from 2 to 6 carbon atoms, preferably from 2 to 4; R3 is a linear or branched alkyl group, having from 2 to 6 carbon atoms, preferably from 2 to 3; n is an integer varying from 1 to 4, preferably from 1 to 2; m is an integer varying from 0 to 4, preferably from 0 to 2; (c) water,- (d) optionally, pigments and/or fillers and/or additives. The present invention also relates to the use of dialkyl carbonates having ether functions as coalescent agents.
