Abstract:
Provided is a (meth)acrylic resin emulsion comprising, as a dispersant, a vinyl alcohol polymer having a degree of saponification of from 80 to 95 mol % and a degree of polymerization of from 400 to 2000 and, as a dispersoid, a polymer comprising at least one type of monomer units selected from acrylate monomer units and methacrylate monomer units, which has a “factor a” of at least 0.3 that indicates the particle size distribution width of the emulsion and of which the film formed at 20° C. to have a thickness of 500 μm has a tensile strength of at least 100 kg/cm2. The emulsion is excellent in all its film strength, film transparency and mechanical stability and further in its alkali resistance.
