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.
L'invention concerne une dispersion liquide aqueuse d'un agent hydrofuge et oléofuge contenant (I) un copolymère choisi entre un composé polymérisable ayant un groupe perfluoroalkyle ou un groupe perfluoralcényle, ainsi qu'un groupe acide acrylique, un groupe acide métacrylique ou un groupe acide acrylique à substitution .alpha., un composé polymérisable contenant du chlore et un autre composé polymérisable facultativement présent lequel est copolymérisable avec les composés précités, et (II) un composé de piégeage d'acide chlorhydrique. Ladite dispersion liquide aqueuse d'agent hydrofuge et oléofuge présente une excellente stabilité de conservation et elle est capable de fournir une matière de base présentant d'excellentes caractéristiques hydrofuges et oléofuges.
