Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid drawing material in which a brush stroke embodies a plurality of colors.

[0002]

2. Description of the Related Art Conventionally, various solid drawing materials for embodying a plurality of colors on a brush line have been studied. For example, a basic core material in which lumped core materials having different tones are dispersed (Jitsuko Sho 39-2).
No. 428), or a continuous crayon of each color is bundled to form a composite crayon, or each color is layered and stacked, or a solid material having an arbitrary color is stacked and pressure is applied to form a random color arrangement (JP 57-202361) and the like.

[0003]

However, in the case where the lumped core material having different color tones is dispersed, the lumpy shape makes the color scheme uniform, resulting in poor color change. Only monotonous color sense can be obtained.
Further, in terms of strength, a sufficient bond cannot be obtained because the bond between the colors is weak. A layered structure of a plurality of colors cannot be obtained sufficiently because the bonding between the color layers is relatively weak in terms of strength although it is molded by pressure. There is little change, and the drawing material must be rotated in order to embody various colors in the stroke line.
Random color schemes by stacking solids of any color are surprising in color development, but lack a subtle change in color scheme, and it is difficult to obtain sufficient strength, and peeling may occur. There is also.

[0004]

The present invention has high strength,
And a solid drawing material for the purpose of obtaining a brush line excellent in decorativeness that embodies a subtle and gradual change in color due to the consumption of the drawing material, that is, the present invention contains a plurality of coloring materials. In the solid drawing material formed as described above, at least one of the plurality of color layers in the longitudinal direction is formed as a mixed layer including a discontinuous layer, and the cross section has a plurality of colors, and the color arrangement changes regardless of the writing direction. At the same time, the main point is a drawing material that gives a surprising stroke.

In the solid drawing material of the present invention, at least one of a plurality of color layers in the longitudinal direction is discontinuously formed, and is composed of a mixed layer of the discontinuous layer and the continuous layer. The continuous layer has its color layer realized until it is completely consumed by one drawing material, and the discontinuous layer is a layer in which the same color suddenly appears or disappears with one drawing material. With this, it is possible to implement a brush line having different colors step by step. Further, the number of colors appearing in the cross section of the solid drawing material is plural. For example, when the number of color layers is 4, the solid drawing material is composed of a discontinuous layer and a continuous layer in the longitudinal direction. The number of colors appearing on a surface can be four, three or two. Therefore, as the drawing material is consumed, unexpected brush strokes are obtained. Here, the number of color layers is 2 or more, but it is preferably 3 or more in order to sufficiently bring out the effect intended by the present invention.

The cross section of the solid drawing material preferably has a marble structure in which each color is intricate. The marble structure shows a pattern form that is diffused and dyed by, for example, the method of sumi-inkashi, and is different from one in which each color is evenly divided, and vivid colors full of stereoscopic effect regardless of the writing direction. It is possible to create a stroke with a sense.

Further, it is preferable that the marble structure is different depending on the position of the solid drawing material in the longitudinal direction.
As a result, the color of the drawn brush line changes subtly as the drawing material is consumed, and the brush line is surprising until the end.

Due to the synergistic effect of the above structure, a plurality of subtle and gradual changes in the color arrangement due to the consumption of the drawing material are realized.
It is possible to obtain a brush line with excellent decorativeness. Further, this feature is freely generated by the above structure regardless of the writing direction, that is, whether or not the drawing material is rotated when writing. Furthermore, since the color layers are intertwined with each other and are bonded to each other and integrated, the drawing material has high strength and does not peel off.

Further, the present invention may have a structure in which a plurality of color layers infiltrate each other at a boundary surface. With this structure, for example, in a two-color boundary surface, by infiltrating each other, a new color is formed in the infiltrated portion. Are formed, and as a result, a three-color or four-color arrangement is obtained, and a more subtle color tone and its change are brought about.

The material used for the solid drawing material of the present invention is
It is appropriately selected according to its shape and specifications. For example, in the case of a crayon, a wax in addition to a coloring material is used as a material thereof, a resin is used, a gel-forming substance is used, or a combination thereof is used. Various constructions such as those described above can be used, and conventionally known extenders, moisturizers, various solvents, dispersants and the like are appropriately added to obtain a drawing material. Of course, the drawing material is not limited to crayon, but it can be applied to lipstick, pass, pencil, sharp lead, solid paint, etc., and conventionally known materials used for these can be used without particular limitation. .

As a preferred example for achieving the object of the present invention, a crayon-like one using a gel forming substance such as a higher fatty acid metal salt as a coloring material and water as a solvent can be mentioned. Examples of the higher fatty acid metal salt include alkali metal salts of higher fatty acids having 8 to 36 carbon atoms. For example, sodium palmitate, sodium stearate, sodium myristate, sodium laurate and the like are preferably used.

The colorant used in the present invention is not particularly limited as long as it is a known pigment or dye that has been conventionally used, and examples thereof include inorganic pigments, organic pigments, fluorescent pigments, metallic pigments and pearl pigments. Colored pigments and the like can be mentioned, and these can be used alone or in combination of two or more. Further, a white pigment such as titanium oxide can be appropriately blended according to the color tone.

In addition to the above materials, polyhydric alcohols such as ethylene glycol, diethylene glycol, glycerin, and diglycerin which have a role as a moisturizing agent, a surfactant as a dispersant, and talc, clay as a filler or a filler, An extender such as silica, kaolin or calcium carbonate may be used in combination. Further, if necessary, an antiseptic agent and a fungicide can be added as appropriate.

Other waxes include, for example, conventionally known waxes such as paraffin wax, polyethylene wax, beeswax, wood wax, and montan wax.
As the resin, carboxymethyl cellulose, nitrocellulose, polyvinyl chloride, polyvinyl alcohol,
Conventionally known synthetic resins such as methyl cellulose, polystyrene, polyethylene, polyvinylpyrrolidone, gum arabic, and natural resins are used.

The above materials are arbitrarily combined according to their respective forms such as crayons, pencils and lipsticks to form a solid drawing material. In order to obtain the drawing material which is the object of the present invention, the above is described. Those using a higher fatty acid metal salt are preferable. It is easy to soften due to heat and flow easily, so it is easy to obtain a solid drawing material with the desired shape, and the color tone is also vivid, so it is excellent in color sense and rich in unexpectedness in multicolor writing A brush line with excellent properties is obtained.

As an example of a gel crayon as a method for producing the solid drawing material of the present invention, first, glycerin and a gel-forming substance are heated and dissolved in a predetermined amount of water at a predetermined temperature with stirring, and further. After adding a colorant and stirring, a sol-like liquid substance is filled in a predetermined mold and solidified by cooling to produce a rod-like gel solidified product. Next, in the same manner, several rod-shaped solidified materials using different coloring materials were prepared,
A rod-shaped body of each color is bundled and vertically packed in an extrusion molding machine and extrusion-molded to produce a core material having a predetermined diameter. This core material is filled in a mold, heated at an appropriate temperature and then cooled and solidified,
Take it out from the mold and use it as a solid drawing material.

According to the above method, the boundaries between the color layers are broken, and the flow of the color layers occurs inside and outside the core material due to the composition, the specific gravity of the materials, the temperature, etc., and the color layers are entangled with each other at the boundaries. Or, while further penetrating each other, a mixed layer in which a continuous color layer and a discontinuous color layer are mixed is formed in the longitudinal direction to form a marble-like structure in cross section, and at the same time, in the longitudinal direction. A solid drawing material having a different marble structure depending on the position of can be obtained. The above structure can be arbitrarily set by adjusting the composition, the specific gravity of the material, the temperature, and the like. Next, examples of the present invention will be described. "Parts" are "parts by weight".
