BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing implement capable of erasing a handwriting with an eraser after writing on paper, cloth, wood, or the like, and more particularly to an oil-based ink for the writing implement. There is a so-called paint marker as a writing instrument containing such erasable ink, but the ink of the present invention is not limited to a specific writing instrument.

2. Description of the Related Art For example, when handwriting is performed on paper using an oil-based paint marker currently on the market,
For example, it cannot be erased using an eraser. Originally,
The paint marker contains ink designed so that the handwriting cannot be erased. However, with respect to water-based inks, attempts have been made to develop inks that can be erased with an eraser (JP-A-8-199103, JP-A-10-103103).

[0005] For example, acrylic resin is originally designed to increase the adhesive strength. Therefore, if such a resin having a large adhesive strength is used, it cannot be erased by an eraser. Therefore, it is preferable to use a resin having a small adhesive force. As a result of our intensive studies, we have found that a rubber-based resin is preferable for this purpose. Rubber-based resins that can be used in the present invention include, for example, styrene-butadiene rubber, polybutadiene rubber, butyl rubber, styrene thermoplastic elastomers, and the like, but are not limited to these specific examples. In other words, any rubber-based resin that is soluble in an organic solvent may be used.

The amount of the rubber-based resin used is 0.1% in the ink.
110.0%. If it is less than 0.1, the erasability is poor, and if it is more than 10.0%, the viscosity of the ink increases, which may be inconvenient.

[0007] The organic solvent that can be used in the present invention is limited to those in which the rubber-based resin is soluble. Examples include xylene, toluene, methylcyclohexane and others.

The pigment which can be used in the present invention is limited to those having a particle size of 1 to 50 microns. For example,
Nippon Shokubai Kagaku's “Epocolor” (approx. 3 microns), Dainichi Seika's “Rabcolor” (approximately 3 microns), and Toyo Alumnium's “Aluminum paste pigment” (approx.
Micron) and "ultra-thin glass flake pigment" (about 40 microns) made by Toyo Aluminum. The particle size is 1
If the particle size is smaller than micron, the pigment penetrates into the space between fibers of paper or the like and cannot be erased by the eraser, which is not preferable. 50
If it is larger than micron, clogging of the ink occurs, which is not preferable.

[0009] The ink of the present invention is prepared according to a conventional method.
It is made by dissolving a resin in an organic solvent and dispersing the pigment in it. If necessary, a dispersing agent, a wetting agent, a viscosity adjusting agent, an antisettling agent and the like can be added.
