Disclosed is an aqueous liquid dispersion of a water and oil repellent agent which contains (I) a copolymer between a polymerizable compound having a perfluoroalkyl group or perfluoroalkenyl group, and an acrylic acid group, methacrylic acid group or alpha-substituted acrylic acid group, a chlorine-containing polymerizable compound, and another optionally present polymerizable compound which is copolymerizable with the foregoing compounds, and (II) a hydrochloric acid trapping compound. Such an aqueous liquid dispersion of a water and oil repellent agent is excellent in shelf life stability, and is capable of providing a base material with excellent water and oil repellency.
