An emulsion includes:
A styrene-acryl-acid grafted polyolefin chloride, which includes a polyolefin chloride structure moiety (1), an acid anhydride and/or carboxylic acid structure moiety (2) bonded to the moiety (1) and a styrene-acryl based polymerization chain moiety (3) bonded to the moiety (2) excluding some of the acid anhydride groups and/or carboxylic acid groups, wherein a ratio of the moiety (2) to a sum of the moiety (1) and the moiety (2) is 1-10 weight %;
an emulsifier;
a basic substance made of at least one of amine compound and ammonia; and
water.
A production process of an emulsion includes the step of preparing a suspension including the respective materials of an emulsion and further includes the step of reacting the materials.
