Description

The present invention relates to a decorative marking pen set, an airbrush kit including the same, and a decoration method.

2. Description of the Related Art Conventionally, in the field of drawing, etc., airbrushes have been used which enable drawing by scattering ink into a mist and spraying the mist ink onto paper or the like. Although it has conventionally been possible to attach an air injection member to an airbrush body, such airbrushes sometimes have the problem of not being able to smoothly replace ink, or problems such as ink clogging.

On the other hand, an airbrush that at least partially solves this problem, for example, attaches a writing instrument and sprays air against the tip of the pen, scattering the ink that has oozed out from the tip of the pen and turning it into a mist. Various airbrushes have been proposed that enable drawing by spraying a mist of ink onto paper or the like.

Patent Document 1 discloses an airbrush unit that includes an airbrush and a writing instrument and jets an aqueous ink composition through air ejected from the airbrush, the writing instrument containing the aqueous ink composition, and An airbrush unit is disclosed in which the aqueous ink composition contains a hiding pigment and has a shear thinning index of 0.4 to 0.8 at a shear rate of 9.6 to 76.6/s. .

The present inventors have discovered that according to the above configuration, it is possible to provide a metallic color that has both good gloss and vividness. This will be explained in detail below.

As shown in FIG. 2(a), when the aluminum pigment 12 and the coloring material 14 are dispersed and applied to the oil-based ink 10, the aluminum pigment 12 is distributed on the surface layer of the ink film as shown in FIG. 2(b). As a result, the colors produced by the coloring material 14 may not appear vividly.

Further, as shown in FIG. 3(a), a first oil-based ink 10 containing an aluminum pigment 12 is applied and dried, and then a coloring material is applied on the applied first oil-based ink 10. When the second oil-based ink 10' is applied, the surface layer of the first oil-based ink 10 is dissolved by the second oil-based ink 10', and as a result, as shown in FIG. The arrangement of the aluminum pigments 12 arranged on the surface layer of the ink film formed by the oil-based ink 10 may be disrupted, and the glossiness may be impaired.

In contrast, in the present invention, as shown in FIG. 1, an oil-based ink 10 containing an aluminum pigment 12 is applied and dried, and then a dye 24 is added to the applied oil-based ink 10. By applying and drying the water-based ink 20, an ink film made of the water-based ink can be placed without dissolving the surface layer of the ink film made of the oil-based ink 10. As a result, it is possible to color with the dye 24 without disrupting the arrangement of the aluminum pigment 12 on the surface layer of the ink film formed by the oil-based ink 10, thereby providing a metallic color with good gloss and vividness. I can do it.
