Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid drawing agent composition for adhering to cloth.
More specifically, a liquid drawing agent that can form a pattern on fabric with excellent texture, flexibility, and wash fastness by simply drawing on the fabric with a chain marking tool or the like, without requiring any special fixing operation. Concerning hol composition.

Conventionally, as a method to easily form a pattern similar to a textile print on a fabric, a crayon-like drawing material is used to draw a desired pattern or color scheme on the fabric, and then a piece of paper is placed on top of this. It is known to heat set the design onto the fabric by placing it and ironing it.

However, the above-mentioned solid drawing materials require a troublesome operation such as heat setting with an iron, and solid drawing materials require delicate or minute touches and thickness compared to drawing with a brush. There is a problem that it is difficult to express the feeling of coating.

Therefore, the object of the present invention is to form a pattern on the fabric that has a good texture and touch and is highly resistant to washing, simply by drawing on the fabric with a marking tool or the like and leaving it to dry naturally. An object of the present invention is to provide a liquid drawing agent composition that can be used for printing.

Still another object of the present invention is to provide a liquid drawing agent composition that colors and fixes the fabric simply by drawing on the fabric, and easily forms a colored pattern without heating or using a fixing agent. There is something to do.

According to the present invention, in a liquid drawing agent composition comprising a composition containing a coloring agent, a binder, and an organic solvent and used for the purpose of drawing on cloth with a writing instrument, the binder is a polystyrene blocked conjugated diene polymer block. Provided is a composition characterized in that it is a thermoplastic elastomer consisting of.

The invention will be explained in detail below.

According to the invention, a thermoplastic elastomer consisting of a polystyrene blocked conjugated diene block is used as at least part of the binder.

This thermoplastic elastomer has highly desirable properties as a drawing agent binder not found in other thermoplastic resins. First of all, this thermoplastic elastomer has rubber-like properties such as high tensile compliance and does not lose its flexibility even at low temperatures, and is soluble in organic solvents and can be firmly fixed onto fabrics without curing or other means. It has a combination of thermoplastic properties.

First, this thermoplastic elastomer generally has a stress of 10 to 60 kgf/c1rL at 600% tension!
As such, it has the characteristics of low modulus, good elongation, and low residual strain.

Therefore, an image created by binding this elastomer with a binder follows the shape change of a flexible or stretchable material such as cloth extremely well, and does not impair the feel of the cloth.

Further, this thermoplastic elastomer is characterized in that its Young's modulus is constant over a relatively wide temperature range. FIG. 1 of the accompanying drawings shows the relationship between the rigidity and temperature of the thermoplastic elastomer (Asahi Kaseidan; Nluprene) A and soft polyvinyl chloride resin B used in the present invention. Referring to FIG. 1, in vinyl chloride resin, the temperature dependence of the rigidity modulus is extremely narrow, and as the temperature W decreases, the rigidity modulus becomes extremely large, whereas the thermoplastic elastomer used in the present invention has a wide The fact that the stiffness modulus is maintained at a relatively low constant value in the temperature range, ie the fiber does not lose its good hand even at low temperatures, is evident.

Furthermore, this thermoplastic elastomer exhibits the advantage of being easily soluble in many organic solvents and having a relatively low solution viscosity. This means that even if the binder is used at a high concentration, the viscosity is relatively low, so it is difficult to obtain a smooth writing feeling.

Furthermore, when this thermoplastic elastomer is used as an inder, it has the remarkable advantage of providing high adhesion to fabrics without the use of hardening agents. Urea resins, melamine resins, phenolic resins, xylene resins, etc., which are widely used in textiles, not only require curing treatment when adhering to fabrics, but also cause the film formed by curing to be hard and uncomfortable to the touch, and may even be difficult to wash. However, in the composition of the present invention,
Since the binder used is a thermoplastic elastomer,
By simply allowing the solvent to evaporate by leaving it to stand, strong adhesion to the fabric can be achieved, and since the formed film is highly flexible, excellent washing fastness can be obtained.

The thermoplastic elastomer used in the present invention consists of a soft segment (rubber-like polymer block) consisting of a conjugated diene polymer block and a polystyrene block.
The polymer blocks are made up of de-segments (polymer blocks in a glass or crystalline state), and the excellent functions described above can be obtained by combining these blocks.

As the conjugated diene polymer block, a polybutadiene block is suitable, but a polyimbutylene block is also used. When polystyrene block 81 polybutadiene block 'cB and polyisobutylene block are represented by I, the block structure of this elastomer is, for example, s.
-n, 5-zSs-n -3, S-1-8, etc.

This thermoplastic elastomer only needs to have a molecular weight that allows film formation.

The thermoplastic elastomer preferably used for the purpose of the present invention contains 60 to 50% by weight of polystyrene blocks, in particular 6% by weight of polystyrene blocks.
It is contained in an amount of 5 to 45 times.

That is, when the content of this polystyrene block is less than the above range, fixing properties and heat fixability tend to decrease, while when it exceeds the above range, flexibility, texture, etc. tend to decrease. There is.

Polystyrene Bronku conjugated diene block elastomers suitable for the purpose of the present invention are commercially available from Asahi Kasei Corporation under the names Tuffprene and Turuprene.

In the present invention, the above-mentioned thermoplastic elastomer is
Colorants and organic solvents are used in combination.

As the pigment used in the present invention, all pigments conventionally used in heat-setting drawing materials can be used.

Suitable examples of pigments include, but are not limited to, the following:

Black pigment: carbon black, lamp black, iron black,
Bone black Yellow pigments: yellow iron oxide, fast yellow, naphthol yellow, titanium yellow, benzidine yellow, chromofukur yellow, disazo yellow, isoindolinone yellow orange pigments: pyrazolone orange, perinone olé red pigments: pengara, linur red, lake red, naphthol Red, brilliant carmine, quinacridone red, perylene red violet pigments; manganese violet, methyl violet lake, dioxazine violet, rhodamine lake, quinacridone violet Evening pigments: navy blue, phthalocyanine blue, gun night, first sky blue, indanthrone blue green pigments : Malachite green lake, phthalocyanine clean, naphthol green white pigment: titanium white, zinc white.

The organic solvent used in the present invention is one that can dissolve the above-mentioned thermoplastic elastomer and disperse the pigment, and includes, for example, hydrocarbon solvents such as cyclohexane, benzene, toluene, and xylene; ethyl acetate, butyl acetate, and lactic acid. Ester solvents such as butyl, alcohol fGWs such as r-thyl alcohol; ether solvents such as diethyl ether; ketone m-solvents such as methyl ethyl ketone and methyl in butyl ketone; carbonized halides such as carbon tetrachloride, chloroform, and trichloroethylene. The hydrogen 6 medium may be used alone or in combination of two or more.

In the present invention, it is desirable to use a slowly volatile solvent such as butyl lactate in combination with an easily volatile solvent. That is, by using such a combination of solvents, it is possible to prevent the binder from sticking to the writing part of a writing instrument, which is excellent. You can obtain a lasting writing quality.

In the present invention, the thermoplastic elastomer contains 10
It is preferable to use the pigment in an amount of 1 to 50% by weight, especially 2 to 45% by weight, and the organic solvent in an amount of 60 to 80% by weight. , preferably in an amount of 35 to 75% by weight, respectively. That is, when the surface area of the thermoplastic elastomer is less than the above range, there is a tendency that the desired fixing properties, waxiness, flexibility, etc. are not obtained, and there is a tendency that the image on the fabric is smeared, and when it is larger than the above range. In some cases, the viscosity of the liquid tends to be too high, reducing the taste. The proportion of the pigment and solvent is preferably changed within the above range from the viewpoint of texture and hue.

The drawing material composition of the present invention can take the form of a rough ink-like form to a somewhat viscous paste depending on the blending amounts of the pigment, thermo-OJ plastic elastomer, and solvent.
These forms are freely selected with regard to the writing performance of the writing instrument.

The drawing material composition of the present invention may contain various auxiliary agents or compounding agents in addition to the above-mentioned essential components.

For example, in order to improve the fixing properties during drawing, tackifiers such as rosin, rosin derivatives such as ester gum, rosin-modified alkyd resins, terpene resins, petroleum resins, etc. can be blended, and such tackifiers can be added in a range of 0 to 0 per total. 8:rlf
It is preferable to incorporate it in an amount of ff%, particularly 2 to 6% by weight.

Another notable advantage of the thermoplastic elastomer used in the present invention is that it has excellent compatibility with tackifiers.

Additionally, non-toxic plasticizers such as cyftyl sebacate and octyl diphenyl phosphate can be added to improve dispersibility. These IJJ plastics range from O to 6 per total.
It is preferred to use amounts of 2% to 2% by weight.

Furthermore, fillers such as calcium carbonate, clay, and Kurji may be added for the purpose of increasing the weight, and other resin binders may be used in combination as binders.
