Title:

INK RECEIVING COMPONENT FOR PRESSURE BALL POINT PEN OR WATER INK RECEIVING COMPONENT FOR WRITING IMPLEMENT

Document Type and Number:

Japanese Patent JP2005205919

Kind Code:

A

Abstract:

To provide an ink receiving component for pressure ball point pen or a water ink receiving component for writing implement for preventing deterioration of the ink and preventing blow off of the ink due to transmission of oxygen in air.

For the water ink receiving component for writing implement equipped with the ink receiving component comprising an organic polymer receiving water liquid ink containing at least color material, resin and antimicrobial materials and the water ink receiving component for writing implement and an nib, the ink receiving component comprises a multi layer structure containing a multi layer structure modified or denatured polyolefin series organic polymer of improving adhesion to an organic polymer of ≤10-10(cc×cm/cm2×sec×cm Hg) at 25°C Dry in oxygen transmission factor. When a layer thickness of each layer comprises the multi layer structure in Ln, an oxygen transmittance factor of the organic polymer of each layer is Pn, and the oxygen transmittance factor P of the whole of the ink receiving component is made the following fomula (I), the P is less than 10-10(unit:the same as shown above). Further, the formula (I) is (L1+L2+..., +Ln)/P=L1/P1+L2/P2+..., +Ln/Pn.
