き出しの場合と同様である。On the other hand, in pastel, in order to secure the fixing property of the pastel powder, there is also a method of fixing the pigment particles to the screen by using a fixer chief in which a resin is dissolved in a solvent as a top coat after the completion of the work. The fixative does not have the ability to block ultraviolet rays, and deterioration of the pigment due to ultraviolet rays or the like is likely to occur, which is the same as in the case of exposing the pigment.

Moreover, since the hue of pastel powder changes depending on the humidity, it has been pointed out that spraying the fixative loses the brilliance of the color and darkens the color depending on the color. That is, the pigment particles absorb the fixative, coalesce, and reorganize, making the pastel image thicker and heavier.

Paying attention to the effect of suppressing the destruction of the molecule, as a result, an ultraviolet absorber and a light stabilizer for suppressing a hue change were added as a composition to obtain a stick-shaped paint composition that is strong against a change in hue due to light or ultraviolet rays. In other words, we came to discover that the composition of the conventionally known rod-shaped paint does not have the durability of the molecule in the pigment against light and ultraviolet rays, and by further research and experiments, the hue change of the paint after drawing In order to suppress the above, it is important to knead and contain an ultraviolet absorber and a light stabilizer, and to set the ratio of the ultraviolet absorber and the light stabilizer in an appropriate range in relation to the drawability of the rod-shaped paint. It was found that there was something, and the present invention was completed.

は良好である。BEST MODE FOR CARRYING OUT THE INVENTION Specific preferred conditions for carrying out the present invention will be sequentially described. First, the extender pigment is not particularly limited, but it is preferable to use a component that has a caking effect, has little shrinkage during drying, is easily disintegrated, and does not increase frictional heat. For example, montmorillonite clay minerals, aluminum silicates such as clay and kaolin, magnesium silicates such as talc, calcium carbonate and barium sulfate can be preferably used. Among these, the most suitable are bentonite, which is a montmorillonite clay mineral, clay, kaolin, and barium sulfate. The content of extender pigment is 4% by weight concentration at the time of composition.
The range of 2.5 to 99.0 wt% is practically suitable, and the range of 49.0 to 98.0 wt% is the optimum range.
If the amount is more than the preferred range, it tends not to collapse when drawing on the drawing surface, the adhesion to the drawing surface tends to be poor, and the coloration tends to be weak. It becomes difficult to mold it as a paint product. Within the above optimum range, the disintegration property, the adhesion to the drawing surface and the color developability are good even if the ultraviolet absorber and the light stabilizer are blended.

と、発色性は良好である。The color pigment is not particularly limited as long as it has a coloring effect. For example, various pigments such as organic pigments, inorganic pigments, pearl pigments, fluorescent pigments, and metal powders can be used. Among these, organic pigments and inorganic pigments are preferable. In particular, organic pigments, unlike inorganic pigments,
There are few problems with heavy metals, many colors can be selected, and the colors are vivid and effective. On the other hand, the inorganic pigment has a porous structure when agglomerated as a stick-shaped paint composition. Therefore, when the inorganic pigment is incorporated into the stick-shaped paint composition, the inorganic pigment easily collapses on the drawing surface and is easy to draw. The content of the color pigment is preferably in the range of 0.5 to 57.0 wt% in terms of concentration by weight in the composition. Among them, 1.0 to 50.0 wt% is the optimum range. If the amount exceeds the above preferred range, it becomes difficult to draw on a paper surface which is a drawing surface, and it becomes difficult to form a stick-shaped paint product. On the other hand, if the amount is less than the above-mentioned preferable range, the color developability deteriorates. Within the above-mentioned optimum range, even if an ultraviolet absorber and a light stabilizer are blended, the drawability, the moldability into a product, and the color developability are good.

く分散させることが好ましい。The UV absorber is not particularly limited, but any UV absorber having a tautomeric function of converting UV energy into heat energy or the like can be used. For example,
Examples thereof include benzophenone-based, benzotriazole-based, salicylate-based, cyanoacrylate-based, nickel chelate-based, oxalic anilide-based, and triazine-based. Among these, benzophenone type, benzotriazole type and triazine type are preferable. The content of the ultraviolet absorber is 0.1% by weight concentration at the time of compounding.
2.0 wt% is a preferable range, of which 0.2 to
The optimum range is 1.4 wt%. If the amount is more than the preferred range, the resistance to the drawing surface of the paper is too high, the fixing property is lowered, and the paper cannot be evenly applied, and it is difficult to draw a continuous line. When the amount is less than the preferable range, the degree of preventing discoloration becomes poor. Within the above-mentioned optimum range, the drawing property, fixing property and light resistance are all better. When the ultraviolet absorber is difficult to dissolve in water, it is preferable to disperse it well before adding it.

よく分散させることが好ましい。The light stabilizer is not particularly limited as long as it has a function of trapping free radicals or suppresses the generation of free radicals. For example, a hindered amine-based antioxidant and a hindered phenol-based antioxidant can be exemplified, and among these, a hindered amine-based light stabilizer is preferable. The content of the light stabilizer is 0.4% by weight concentration.
The preferred range is 10.0 wt%, of which 0.8
The optimum range is ˜7.0 wt%. If the amount exceeds the above-mentioned preferable range, there is too much resistance with respect to the paper which is the drawing surface, and the fixability deteriorates. On the other hand, if the amount is too small, the light resistance for preventing discoloration becomes poor. Within the optimum range described above, the drawing property, fixing property and light resistance are all better. If the light stabilizer does not dissolve in water like the ultraviolet absorber, it is preferable to disperse the light stabilizer well before adding the light stabilizer.

が悪くなり、過少であると耐久性が良くない。The UV absorber and the light stabilizer are effective in both cases, if they are blended alone or as a mixture of both. This is because the ultraviolet absorber is an additive that converts the energy of ultraviolet rays into heat energy, etc., while the light stabilizer traps free radicals generated from pigment molecules or suppresses the generation of free radicals. is there. However, as a result of diligent studies, it was found that it is important to mix both the ultraviolet absorber and the light stabilizer, or at least the light stabilizer in the system of the rod-shaped paint composition. This is because, in the case of a rod-shaped paint composition, a light stabilizer more effectively exhibits light resistance, and when a mixed additive having a smaller blending ratio of the ultraviolet absorber is used, more excellent light resistance is exhibited. We have obtained the knowledge. In short, it is most desirable to use both the ultraviolet absorber and the light stabilizer in the mutually complementary relationship by adjusting the mixing ratio. Specifically, the mixing ratio of the ultraviolet absorber and the light stabilizer is 25 to 100 wt% of the light stabilizer to the mixture of the ultraviolet absorber and the light stabilizer.
%, Preferably 50-100 wt%, optimally 75-99 wt%
% Is preferably included. When it is less than 25 wt%, the light resistance is not so much improved. Within the preferred range
The light resistance is improved, and within the optimum range, the light resistance has a maximum value. Further, when both the ultraviolet absorber and the light stabilizer are blended, the mixed addition amount is different depending on the content of the light stabilizer, but the preferable range is 1 to 10 wt%, 3 to 7 wt% is the optimum use. It is a range. If it is added in excess of the preferred range, the adhesion will be poor, and if it is too small, the durability will be poor.

Knead for 30 minutes. Subsequently, a stick-shaped paint which prevents discoloration due to ultraviolet rays is obtained by molding with an extrusion molding machine, cutting into an appropriate size, and drying in a drying chamber.

になる。If the stick-shaped paint composition is specified at the manufacturing stage, as described above, water, that is, molding water constitutes one component of the composition. However, the stick-shaped paint composition of the present invention can be used to form the paint after molding. Water is not specified as the main component because it is specified by the product. However, the molding water is necessary for forming a clay-like paste at the time of stirring the raw materials and then molding it. Therefore, if the blending amount of this molding water is specified by the weight% concentration, 10.0 to 25.0 wt% is preferable. The optimum range is 12.0 to 20.0 wt%. If the amount exceeds the above-mentioned preferable range, the resin becomes soft and difficult to mold. In addition, the dispersibility of the color pigment decreases. On the other hand, when the amount is less than the above-mentioned preferable range, it becomes too hard and does not become clay-like and is difficult to mold. The water in the composition at the time of final molding according to the present invention is not particularly limited, but as described above, molding water is removed in the drying step to obtain about 1.0 to 7.
It is desirable that the content is 0 wt%, and the average content is about 4.0 wt%. If the value is in excess of this value, there will be a sparse arrival on the paper surface when drawing, and if it is in an insufficient amount, it will feel faint.

In particular, the ultraviolet absorber is at least one of benzophenone-based, benzotriazole-based, salicylate-based, cyanoacrylate-based, nickel chelate-based, oxalic acid anilide-based, and triazine-based, and the composition at the time of compounding is 0.1 to 2.
When blending 0 wt%, and the light stabilizer is either hindered amine light stabilizer or hindered phenol antioxidant, and the composition at the time of blending is 0.4 to 10.0 wt%, when drawing on the drawing surface Has good disintegration properties, adhesion to the drawing surface, and color development.

される。As the color pigment, an organic pigment is more suitable than an inorganic pigment. This is because some inorganic pigments are toxic, such as cadmium yellow, and may be limited in terms of use if safety is important. However, when an organic pigment is molded as a rod-shaped paint composition and agglomerated into a solid, the inorganic pigment is likely to collapse in drawing in a porous manner, whereas in the case of an organic pigment, its structure becomes dense, so that the drawing surface The disintegration property with respect to is decreased and the fixing property becomes poor. Therefore, when an organic pigment is used as a rod-shaped paint composition, the blending amount is more limited than that of an inorganic pigment. On the other hand, since the pigment itself originally has light resistance, the more the amount is increased, the more the light resistance is increased, but as described above, in the case of the organic pigment, the blending concentration is naturally limited, but the present invention According to this, since the light resistance is achieved by a light stabilizer or the like, the light resistance is sufficiently covered even if the compounding amount of the organic pigment is reduced.

In the case of Comparative Example 5 in which the light stabilizer was excessively added from 3.0 wt% to 10.0 wt%, compared with Example 5, when added in excess, both the coloring property and the light resistance were lowered. Regarding the coloring pigment, the use of a high light resistance pigment shows a higher value in light resistance, but even when an ultraviolet absorber or a light stabilizer is added, it shows the same effect of increasing light resistance as a general pigment. And stable in colorability.
