る。 Conventionally, extremely high-quality pencils have been decorated with three-dimensional patterns formed on their tail ends. This can be done by repeatedly applying abrasive powder to the end of the pencil several times to create a rounded, three-dimensional shape, and then forming a colored layer on top of that by dip-painting enamel-lacquer. Methods such as polishing the surface into a convex arc surface and repeatedly applying enamel-lacquer dip coating several times are used, but all of these methods require a lot of work and require a lot of drying time between each coating process. The drawback is that it takes time and leads to an increase in costs.

Since it uses a method of forming directly on the tail end, the resin not only has better permeability into the conduit of the pencil shaft than, for example, when using an ultraviolet curing resin made of epoxy resin. , the tail end of the pencil on which the cured resin coating layer made of the ultraviolet curable resin is formed is a convex arc surface, compared to the case where the tail end of the pencil is formed on a flat surface. The area of the adhesion surface between the pencil and the cured resin coating layer is large, and a cured resin coating layer with extremely good adhesion between the tail end face of the pencil and the cured resin coating layer is formed, making it resistant to impacts, etc. It also has the effect of forming a three-dimensional pattern on the tail end of the pencil, which has extremely high peel resistance.
