By the way, according to the writing tool disclosed in Patent Document 1 described above, although the prism type retroreflective surface is provided on the side surface of the barrel, the reflected light obtained by this prism type retroreflective surface is the reflected light of only a single color. It becomes.
Therefore, according to the writing tool disclosed in Patent Document 1, although a certain effect of enhancing the visibility by the reflected light can be obtained under the condition of retroreflective light such as when the light is directly irradiated, this is monotonous. It must be said that the appeal effect is insufficient due to the reflected light, and the visual effect is not enough.

Therefore, the main problem to be solved by the present invention is under the condition of diffused light in which light is reflected and scattered as in a normal environment, and under the condition of retroreflective light in which light is directly emitted. The point is to provide a writing tool with further improved visual effect by providing a decorative body that causes different visible information and reflected light to appear.

In the writing tool according to the present invention made to solve the above-mentioned problems, visible information can be visually recognized through a latent image under the condition of diffused light, and the latent information is caused by retroreflective under the condition of receiving direct light. It is characterized in that a decorative body on which the image is visualized is provided on at least a part of the exterior portion.

In this case, the decorative body is arranged on the back side of the latent image forming layer on which the latent image is formed by a light transmitting material capable of retroreflective and the visible information. The writing tool is configured by being composed of the information forming layer and the decorative body attached to the writing tool main body.

In addition, the light-transmitting material is preferably transparent microspheres, and it is desirable that the latent image is formed by the collection of the transparent microspheres.
On the other hand, as the information forming layer, a layer in which visible information including characters, patterns, drawings, photographs, and the like is written is used.

According to the writing tool according to the present invention, a latent image forming layer in which a latent image is formed by a light transmitting material capable of retroreflective, and an information forming layer in which visible information is written on the back side of the latent image forming layer. The decorative body having the above is attached to at least a part of the writing instrument main body.
Therefore, under the condition of diffused light in which light is reflected and scattered as in a normal environment, the visible information written on the cambium can be visually recognized through a light-transmitting latent image. Further, under the condition of receiving direct light, a latent image made of a light-transmitting material capable of retroreflective can be seen in a bright and conspicuous state by visualization by retroreflective.

This makes it possible to make different visible information and images with retroreflective light appear under the conditions of diffused light and retroreflective light.
Therefore, due to the rarity of visual effects in which visible information and retroreflective light appear depending on the light conditions, it is possible to give a sufficient visual effect to the customer. This will contribute to the provision of writing tools that can further differentiate products at stores and the like.
