A coating agent aqueous dispersion comprising, as solid matters, 20 to 80 wt. %, preferably 29 to 70 wt. %, of PTFE, 10 to 50 wt. %, preferably 14 to 36 wt. %, of acrylic resin, and 10 to 50 wt. %, preferably 20 to 45 wt. %, of ethylene-vinyl acetate copolymer resin. When the coating agent aqueous dispersion of the present invention is used as a surface-treating agent for rubber-made sealing materials, etc., a reduction in stickiness to the sealing mate material and the prevention of blooming on the surface of the rubber material are obtained. Combined with the flexibility, the adhesion balance between the rubber material and the coating agent is excellent.

[Problem to be Solved]

A displacement prevention coating agent is provided which can prevent a displacement in lens processing, which is soluble in water and which exhibits a transparent appearance at least after being cured.

[Solution] There is provided a displacement prevention coating agent with which the front and rear surfaces of a lens are coated so that when cutting processing is performed on an end surface of the lens where, for example, a water-repellent coat layer is formed as a membrane such that the end surface has a shape corresponding to a frame, a holding position of the front and rear surfaces of the lens held by a chuck device is prevented from being displaced, where the displacement prevention coating agent is formed of an aqueous solution whose main components are a hydrophilic resin, a surfactant having a perfluoro group and an emulsion and exhibits a transparent appearance at least after the formation of the membrane. Such a displacement prevention coating agent is used when the front and rear surfaces of a lens where for example, a water-repellent coating layer is formed as a membrane are chucked and held with a chuck device to which an adhesive tape is adhered, and thus when the lens is processed, a holding position held by the adhesive tape of the lens is unlikely to be displaced.
