る。BACKGROUND OF THE INVENTION The watercolor paper used for drawing watercolors depends on the type of papermaking fibers used as raw materials.
It is usually divided into three grades. The highest grade is called "the finest watercolor paper" and contains almost 1
Manufactured using 100%. The one with a slightly lower grade is called "high-grade watercolor paper" and is produced by using wood pulp in combination with cotton pulp. The worst grade is simply called "watercolor paper" and is made entirely of wood pulp. "High-end watercolor paper" and "luxury watercolor paper" are used for upper and intermediate levels, and simple "watercolor paper" is used for beginners. Hereinafter, the finest watercolor paper and the high-grade watercolor paper will be collectively referred to as “high-grade watercolor paper”. The present invention has the same performance as this “high-grade watercolor paper”
The present invention relates to a new proposal regarding a method for producing watercolor paper .

Some of the watercolors are drawn by transparent or semi-transparent drawing, and some are drawn by using opaque paints (tempera, gouache, etc.).

より紙の強度が劣化しないことが好ましい。Water-based paint is prepared by diluting water-based paint with water. When drawn with a paintbrush or the like, it is preferable that the dilution water of the paint penetrates the inside of the paper, and only the pigment of the paint is uniformly fixed on the surface of the paper. For this reason, the watercolor paper is required to have appropriate water absorbability of water-based paint and uniform color development. Further, it is preferable that the strength of the paper does not deteriorate with time so that the work can withstand long-term storage.

った。Regarding the water absorbency of a suitable water-based paint, the above-mentioned simple "watercolor paper" for beginners has been designed so that it can be repainted while suppressing the water absorbency. On the contrary, "high-quality watercolor paper" is designed so that the water of the water-based paint is quickly absorbed inside the paper. That is, the grade of watercolor paper depends on water absorption, and the higher the water absorption, the higher the grade. It is known that this characteristic can be obtained mainly by selecting the kind of pulp as a raw material. As a raw material for high-grade watercolor paper, cotton pulp, which has a higher degree of cellulose purity than wood pulp and is superior in water absorbability, has been used for a long time. Contains a lot of. However, cotton pulp has good water absorbency, but has a drawback that it is expensive and fluffing easily occurs.On the other hand, wood pulp is cheap and fluffing is hard to occur, but it is poor in water absorbability and has satisfactory performance as a high-grade watercolor paper. There was a problem that I could not get it.

As a result of examination, the present inventor found that the same applies to watercolor paper. Generally, when a rosin-based sizing agent is used, it is necessary to use aluminum sulfate or the like as a fixing agent. Since this fixing agent can act as a catalyst for hydrolysis of cellulose, it is said to cause deterioration over time. The epoxidized higher fatty acids and / or alkyl ketene dimers that are preferably used in the present invention are cationic and fix to negatively charged papermaking pulp without the presence of a fixative. Therefore, the thereby less time degradation luxury watercolor paper
A watercolor paper with equivalent performance can be obtained. Also,
Acids used as various auxiliary materials for papermaking are also said to cause deterioration over time. Therefore, also in the present invention, various auxiliary materials for papermaking can be used within the range that does not impair the purpose, but the use of cold water extraction pH of paper is 6.0 to 6.0.
It is preferable to perform the treatment within a range of 9.5.

With the internal addition method, a water-soluble polymer is added to a slurry in which raw materials are mixed, and a fixing agent is used to fix the pulp on the pulp.
This is a method of papermaking. The wet impregnation method is a method of impregnating the inside of the web with an impregnating liquid containing a water-soluble polymer before the raw material is made into paper and dried. The dry impregnation method is a method in which a raw material is made into paper, dried and then impregnated with an impregnating solution containing a water-soluble polymer using an off-machine or on-machine impregnator. The coating method is a method in which a raw material is made into paper and dried, and then a coating solution containing a water-soluble polymer is applied using an off-machine or on-machine coating machine.

ないのである。Although there are various methods for attaching the water-soluble polymer to the paper, the watercolor having the same performance as the high-grade watercolor paper of the present invention.
Paper can only be produced by the wet impregnation method. Other methods, for example, the inner addition method, dry impregnation method, the reason why that can not be manufactured by the coating method or the like, equivalent to higher watercolor paper by these methods
The water absorbency of water-based paint required for the watercolor paper having the above performance cannot be obtained, and the uniform color development of the paint cannot be obtained. The cause is that there are few voids in the paper layer to physically permeate water, and because the water-soluble polymer attached in the paper layer is non-uniform, water accumulates on the paper surface, The inventor of the present invention speculated that the ride of the paint was uneven. In particular, when wood pulp is used, the fibers are flattened, so that the fibers are easily crushed during beating and papermaking. Therefore, the fibers are easily adhered to each other and the voids in the paper layer are smaller than in the case where cotton pulp is used, so that it cannot be produced by a method other than the wet impregnation method.

れる。On the other hand, as a result of the study by the inventor of the present invention, in the wet impregnation method, sufficient water absorption required for a watercolor paper having the same performance as that of high-grade watercolor paper was selected without selecting the kind of pulp. It has been found that good color development is obtained and uniform color development is obtained. The inventor of the present invention presumed the reason as follows. That is, in the case of the wet impregnation method, the water-soluble polymer adheres in a state where the fibers are not in close contact with each other, so that the water-soluble polymer adhered to the fiber-to-fiber intersections inhibits the fiber-fiber bond. Therefore, there are appropriate voids in the paper layer. Also,
In the case of the wet impregnation method, the water-soluble polymer is uniformly attached not only to the surface of the paper layer but also to the inside. Therefore, the water absorption is remarkably increased, and the above effect is obtained. Further, the effect of improving the strength between the paper layers and making it less likely to cause fuzzing can be obtained.

なり、見た目の発色濃度が高くなる。In the present invention, the wet paper on the papermaking or paper machine may be embossed. The following effects can be obtained by performing the embossing process. When you draw with a paintbrush etc., the tip of the brush will slightly catch on the unevenness of the paper, so it will not slip too much and the drawing comfort will be improved. In addition, the work feels like it was drawn on a canvas, which gives the work a high-class feel. Furthermore, since the surface area is increased due to the fine irregularities, the amount of the pigment fixed in the paint per unit area of the paper is increased, and the apparent color density is increased.

性が劣り、かつ表面の毛羽立ちが多い。As is clear from Table 1, the watercolor paper having performance equivalent to that of the high-grade watercolor paper of the present invention is excellent in any of water absorbency, uniform color development, and fuzz on the surface. Some of the pulps having a low content of cotton (Examples 1 to 8) are slightly inferior in water absorption and uniform color development, but there is no problem in practical use. Some of the high cotton contents (Examples 9 to 11) have a little fuzz on the surface, but there is no problem in practical use. The products containing synthetic pulp (Examples 12 and 13) were slightly inferior in absorbability and uniform color development, but there was no problem in practical use. However, as can be seen from the comparative example, if the freeness is too low (Comparative Example 1), it lacks in water absorption, water accumulates on the paper surface, and uneven coloring occurs.
On the other hand, if the freeness is too high (Comparative Example 2), the water absorption is high, but the water absorption is uneven, resulting in uneven color development. Even if the freeness is within a certain range, the amount of the water-soluble polymer attached is too small (Comparative Example 3), the amount of the water-soluble polymer attached is too large (Comparative Example 4), and the dry impregnation method is used. The water-soluble polymer adhered (Comparative Example 5) and the water-soluble polymer not adhered (Comparative Example 6) have poor water absorption and poor color development. The water-soluble polymer adhered by the coating method (Comparative Example 7) is inferior in absorbability and uniform color development, and has a lot of fuzz on the surface.
