及ぼす欠点もあった。Conventionally, the method of painting the end of a pencil is to first apply two or three coats of solvent-type or emulsion-type vinyl acetate resin paint or lacquer enamel as an undercoat process and harden it, and then apply one coat of lacquer enamel as a topcoat process. harden,
It is common to perform a printing process thereon. However, in the undercoating process, it takes 1 to 3 hours for the paint to harden, and the number of coats is also required. The curing time of the lacquer enamel is 1 to 3 hours in the overcoating process, and the curing time of the printing ink in the printing process is 3 to 5 hours, which slows down the entire process. The problem was that it took too much time to improve productivity. In addition, the paint and ink solvent evaporates during each process, which has a negative impact on the human body.
本発明は斯る従来方法の有する欠点を解消し。The present invention overcomes the drawbacks of such conventional methods.

徴としてその目的を達成せんとするものである。The purpose is to simplify the process and improve productivity, as well as to make it non-polluting.The material surface of the tail end of the pencil body is first coated with an undercoat process using ultraviolet curable paint, and then transferred to the surface. This objective is achieved by applying an overcoating process of coloring or printing with foil.

間が数秒乃至数分で済む。The UV-curable paint used in the undercoating process consists of a polymerizable double bond-containing prepolymer as a base resin, a polymerizable monomer as a viscosity adjuster and crosslinking agent, and a photosensitizer to initiate the polymerization reaction. Examples include acrylates of saturated polyester, epoxy, urethane, polyester, and polybutadiene. The monomers contained in this UV-curable paint are slightly volatile, but after curing, they become part of the structure of the cured product, making them almost non-volatile.Also, they have sufficient durability, making them easy to apply. only needs to be done once. Furthermore, since the curing mechanism is a radical polymerization reaction using ultraviolet rays, the curing time is only several seconds to several minutes.

ができる。Transfer foils used in the overcoating process include multicolored foils, single-color foils, and vapor-deposited foils.For example, vapor-deposited foils have a laminated structure of a thermal adhesive layer, an aluminum vapor-deposited layer, a protective coating layer, and a transfer film, and cannot be heated. The heat heel adhesive melts and adheres to the object to be transferred, leaving a base film behind, and is immediately colored and does not require any drying time. If a printing foil is used as the transfer foil, the printing process that is normally performed after the top coating process can be absorbed and completed in one process.

After being cured by irradiation with ultraviolet rays for several seconds to several minutes, the transfer foil is pressed and the transfer layer (4 ) was formed.
