Abstract
Official abstract text for this publication.
This oil-based ink composition for writing implements contains a colorant, a resin, an organic solvent, and fluorine-based resin particles, the average particle size of the fluorine-based resin particles being at least 0.1 μm and less than 1.0 μm when measured by a dynamic light scattering method.
First claim
Opening claim text (preview).
The invention claimed is: 1. A marking pen or a ballpoint pen comprising at least an ink storage portion, a writing portion, a holding portion, and an oil-based ink composition, wherein the oil-based ink composition is stored in the ink storage portion, said oil-based ink composition comprising a colorant, a resin, an organic solvent, and a powder of polytetrafluoroethylene particles having a melting temperature from 325° C. to 335° C., wherein the average particle size of the powder of polytetrafluoroethylene particles is in the range of 0.1 μm to less than 1.0 μm as measured by dynamic light scattering, and wherein the content of the powder of polytetrafluoroethylene particles is 3 to 25 mass % based on the total mass of the oil-based ink composition.
