Technical Examples
  1. An aqueous resin composition satisfying the following criteria (I)-(III). (I) The aqueous resin composition contains (a) an aqueous dispersion of a polyurethane resin obtained from a macromolecular polyol, organic polyisocyanate, chain extending agent and 2,2-dimethylolbutanoic acid, and, if required, (b) an aqueous dispersion of an acrylic resin. (II) When the resin comprising this aqueous resin composition contains mainly a polyurethane resin, the inherent viscosity (?inh) of the polyurethane resin measured at a concentration of 0.5 g/dL in dimethylformamide solution is in the range of 0.2-0.7 dL/g. After this aqueous resin composition is dried, the elastic modulus at 25° C. of the film obtained by heat treatment at 80° C. for 8 hours is in the range of 8.0×10
