Example Embodiment

[0073] The preparation of the collapsible colored particles is to put the coloring substance and the body into a mixer or pulverizer / mixer for thorough mixing, and then gradually add a solution or dispersion of the binder component to achieve thorough mixing. Subsequently, the mixture is granulated. As the mixer or pulverizer / mixer, a Henscel mixer or a homogenizer-mixer is preferably used, although they are by no means limited to these. The mixer performs mixing and granulation at the same time, so it is very convenient.

[0074] As the solvent for the solvent-soluble polymer material, depending on the type of polymer material, one or two or more aliphatic hydrocarbon solvents such as hexane; aromatic solvents such as toluene and xylene; alcohol can be used. Solvents such as methanol, ethanol and butanol; ether solvents such as diethyl ether and tetrahydrofuran; ketone solvents such as methyl ethyl ketone and cyclohexanone; cellosolve solvents such as methyl cellosolve and butyl ...

[0098] The present invention will now be further explained in conjunction with examples, but the present invention is not limited to these examples.

Example Embodiment

[0099] (Example 1)

[0100] 1-A parts by weight

[0101] Talc 3.8

[0102] C.I. Pigment Yellow 1 0.4

[0103] C.I. Pigment White 6 0.3

[0104] Aqueous solution containing 25% carboxymethyl cellulose 1

[0105] Talc, C.I. Pigment Yellow 1 and C.I. Pigment White 6 were put into a Henschel mixer, and then an aqueous solution containing 25% carboxymethyl cellulose was gradually added with stirring to form pellets with a size of 3 to 5 mm. The pellets were then dried at 70°C to completely drive off the moisture. The pellets are crushed to a size of about 1 mm by a pulverizer, and then sieved to remove particles with a diameter of not more than 0.05 mm and a diameter of not less than 2 mm, thereby obtaining yellow pellets.

[0106] C.I. Pigment Yellow 1 was replaced with C.I. Pigment Orange 13, C.I. Pigment Red 57, C.I. Pigment Blue 15, C.I. Pigment Green 7, and C.I. Pigment Violet 23, thereby similarly obtaining orange, red, blue, green, and purple pellets.

Abstract

A multi-color pen or oil-based crayon characterized by excellent drawing performance, vivid colors, and tight adhesion of multi-color drawings, and a production method thereof. The multicolor crayons or oil crayons comprise a continuous matrix of crayon or oil crayon material and a plurality of granular coloring phases dispersed in the matrix, wherein the granular coloring phases are composed of collapsible granular materials comprising: a hue different from Continuous matrix of coloring substances, bulk and water-soluble or solvent-soluble polymeric materials or water-swellable clay minerals (eg bentonite).

Description

technical field [0001] The invention relates to a crayon or an oil pastel and a production method thereof. More specifically, the present invention relates to a multi-color pen or oil-based crayon characterized by combining excellent drawing performance, vivid colors, and tight adhesion of multi-color pictures, and a production method thereof. Background technique [0002] Solid drawing materials are known to incorporate a variety of different shades. [0003] Japanese Examined Utility Model Publication (Kokoku) 2428 / 1964 discloses a colored pencil in which the core material is formed by dispersing agglomerate core materials of several different shades into a color substance of the basic color, thereby forming Colored surface of core material that varies discontinuously across the face and is surrounded along the lengthwise circumference by core protection (prior art a). [0004] Also, Japanese Unexamined Utility Model Publication (Kokai) 86141 / 1976 discloses a colored pen...
