preparation example Construction

[0073] Collapsible colored particles are prepared by putting the coloring matter and the body into a mixer or pulverizer / mixer for thorough mixing, and then gradually adding a solution or dispersion of the binder component to achieve thorough mixing. Subsequently, the mixture is granulated. As the mixer or the pulverizer / mixer, it is preferable to use a Henscel mixer or a homogenizer-mixer, 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 a solvent for solvent-soluble polymer materials, depending on the kind of polymer materials, one or two or more aliphatic hydrocarbon solvents such as hexane and the like; aromatic solvents such as toluene and xylene; alcohols 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 cellos...

[0101] Talc 3.8

[0102] C.I. Pigment Yellow 1 0.4

[0103] C.I. Pigment White 6 0.3

[0104] 25% carboxymethyl cellulose in water 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% carboxymethylcellulose was gradually added under stirring to make pellets with a size of 3-5 mm. The pellets were then dried at 70°C until the water was completely driven out. The pellets were pulverized to a size of about 1 mm using a pulverizer, and then sieved to remove particles not larger than 0.05 mm in diameter and not smaller than 2 mm in diameter to obtain yellow pellets.

[0106] Pigment Yellow 1 was exchanged for 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 to similarly obtain 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...
