Zusammenfassung:	A film-forming composition including a water-based film-forming polymer having a minimum film forming temperature and a diester(s) of one or more dianhydrohexitols, wherein said dianhydrohexitol diester has a volatile organic content of less than 20 wt.%. Use of such film-forming compositions reduces minimum film forming temperature of the water based film- forming polymer by 10° C to 30° C; and produces a film on a surface wherein said film has properties selected from the group consisting of: 20° gloss value, 60° gloss value, hardness value and combinations thereof, comparable to a film formed from a water based composition containing a standard coalescent aid. The dianhydrohexitol diester includes an isosorbide diester where the ester group has three to 8 carbon atoms. The water based film-forming polymer includes an acrylic resin, a vinyl acrylic resin, a styrene acrylic resin, a vinyl acetate ethylene resin, alkyd resin, ethylene vinyl acrylate resin and combinations thereof.
