Abstract
A coating film and a method for forming the same are provided. The coating film controls reduction in repellency of hydrophobic fine particles and increases rub fastness of the coating film. The coating film includes a ground layer containing thermoplastic resin (chlorinated polyolefin or acid modified chlorinated polyolefin, for example) and an upper layer containing hydrophobic fine particles (hydrophobic silica particle or silicone resin particle, for example) formed on the ground layer. Parts of the hydrophobic fine particles contained in the upper layer are buried in the ground layer.
Claims9
A coating film comprising:
- a ground layer containing a thermoplastic resin;
- and
- an upper layer containing a hydrophobic fine particle, the upper layer being formed on a surface of the ground layer;
- wherein the hydrophobic fine particle includes a part buried in the ground layer.
A method for forming a coating film, the method comprising:
- applying a thermoplastic resin dissolved in a solvent onto a surface of a target object to form a ground layer on the surface of the target object by drying the thermoplastic resin;
- applying a hydrophobic fine particle dissolved in another solvent onto the ground layer;
- and
- drying the hydrophobic fine particle applied on the ground layer to form an upper layer.
