ABSTRACT:
An electrostatic flocking product in which flocks are fixed to the surface of a base material through an adhesive layer. The adhesive layer of the electrostatic flocking product is formed by polyurethane prepared by curing a mixture of an isocyanate prepolymer and polyisocyanate, with water, and the polyol raw material for the foregoing isocyanate prepolymer is a mixture of a high polyol as the main component and triethanolamine in a specific mixing ratio. The electrostatic flocking product of this invention has sufficiently high abrasion resistance at the flocked surface and the foregoing water-cured polyurethane for forming the adhesive layer of the electrostatic flocking product of this invention shows good coating workability at the formation of the adhesive layer.
