Latest Patents

One of Yasui's latest patents is a method of coating a pencil. This method allows for the coating of the surface of a pencil barrel with a coat film that achieves sufficient thickness and smoothness using a hot-melt polyester as a coating material. The desired coat film can be formed on the pencil barrel with just a single coating operation. The hot-melt polyester exhibits excellent affinity and improved adhesion to both the pencil barrel and any lacquer that may be applied afterward. Importantly, this method eliminates the need for organic solvents and significantly reduces the time required for the coating operation, making it advantageous for both environmental protection and productivity enhancement.

Another significant patent by Yasui is a process for injection molding a polyester with improved crystallization. This process involves incorporating a crystallization accelerator into the polyester prior to molding. The accelerator includes a compound with at least one aromatic ring, such as a benzene, naphthalene, or anthracene ring, along with sulfonic acid alkali metal salt groups and phenolic hydroxy alkali metal salt groups. This innovation improves the crystallization properties of the polyester during the injection molding process.
