ルに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coated white ball, and more particularly, to offset white printing on a back white layer of a coated white ball in which a low whiteness pulp, particularly unbleached used paper is multiply incorporated in a back layer. Even, ink color development,
The present invention relates to a coated white ball which is excellent in print gloss and the like, hardly adheres foreign matter to a blanket and a printing plate when offset printing is performed on the surface, and has good white spot resistance on a printed surface.

られるようになってきた。2. Description of the Related Art White paperboard is divided into manila balls and white balls. Manila balls are classified into high-grade paperboard, special paperboard, and general manila balls. Conventionally, when performing offset printing on the back surface of white paperboard, a manila ball excellent in offset printing suitability on the back surface has been exclusively used. However, in recent years,
Offset printing has also been seen on white balls and on the back.

% Or less, even when the offset printing is performed on a white ball having a value of not more than 10%, the color of the ink usually becomes a dull stamped surface. Therefore, for white paperboard to be printed on the back surface, conventionally, bleached chemical pulp, bleached mechanical pulp, deinked waste paper pulp, and the like have been blended in the back layer.

There is a problem that the transfer occurs, which causes white spots on the stamp face. As countermeasures, applying polyvinyl alcohol, polyacrylamide, starch, etc. to the back surface, internally adding a paper strength agent to the back layer, reducing the amount of waste paper pulp in the back layer pulp, waste paper pulp with a long fiber length In the case of using waste paper pulp having a short fiber length, it has been practiced to enhance washing or kneading treatment to mix.

ないものが得られていないのが現状である。However, low-grade waste paper pulp having a short fiber length and low whiteness is blended in the backing layer, and the whiteness of the backing layer peeling surface is 5%.
At present, less than 5% of white paperboard has not yet been obtained that has good ink coloring properties when printed on the backside of the offset and has little white spots on the stamped surface.

In addition, if the used paper is also subjected to the deinking process, there is a problem that drainage becomes dirty and the load increases. Therefore, if used paper can be used without deinking, it can greatly contribute to solving this problem and social issues.

Another object of the present invention is to provide a coated white ball which is excellent in white spot resistance of a stamped surface when printed on a surface, and which has a good suitability for breakage in box making.

来ることを見出し本発明を完成するに至った。Means for Solving the Problems As a result of intensive studies, the present inventors have prepared two or more layers, and have a whiteness of 55% or less on the peeling surface of the backing layer after peeling off the backing layer. In a coated white ball for applying the composition, the pigment coating composition was applied to the back surface and dried, and the whiteness of the back layer coating surface after the smoothing treatment was 45%.
%, It was found that the above-mentioned object could be achieved, and the present invention was completed.

られる。DESCRIPTION OF THE PREFERRED EMBODIMENTS The reason why the object can be achieved by the present means is presumed as follows. That is, by coating the back surface with the pigment coating composition, the voids formed by the pulp fibers are filled. Therefore, when the coating composition is not applied, the ink penetrates into the voids to develop color and gloss, but on the other hand, when the coating composition is applied, the voids are filled, The ink does not penetrate and can be left on the back surface layer. For this reason, it is considered that the color and gloss of the ink are improved even with a white ball having a low whiteness of the back layer.

古紙の有効利用の観点から非常に好ましい。However, the pigment coating composition is coated and dried,
When the back layer coated surface whiteness after the smoothing treatment is less than 45%,
Ink color is not good. Further, the whiteness of the back layer peeling surface is 55.
%, It is not preferable because a low whiteness non-deinked waste paper pulp cannot be mixed in a large amount in the back layer. The pulp to be blended in the back layer is not particularly limited as long as the whiteness of the back layer peeling surface after the back layer peeling is 55% or less. % Is very preferable from the viewpoint of effective use of low-grade waste paper.

なる傾向になるからである。Further, when the pigment coating composition is applied to the back surface, the pulp fibers of the back layer are coated and fixed by the pigment coating composition, so that the transfer of the pulp fibers to the surface coating surface is prevented. It is considered that white spots are prevented from occurring in the image. The coating amount of the pigment coating composition is not particularly limited as long as the whiteness of the back layer after the smoothing treatment can be 45% or more, and is preferably 3 to 20 g / m 2 . If the amount is less than 3 g / m 2 , it often becomes difficult to develop ink color or print gloss, and if it exceeds 20 g / m 2 , the ink color or print gloss is improved even if the coating amount is increased. This is because the effect tends to decrease.

You. These may be used alone or in combination of two or more. In particular, when a latex having a glass transition temperature of −50 to 0 ° C. as measured by vibron viscoelasticity is blended, the flexibility of the coated surface is increased and the breakage resistance is improved, so that it can be suitably used. The blending amount of the latex is preferably 12 to 25 parts by weight based on 100 parts by weight of the pigment. If the amount is less than 12 parts by weight, the above effect is slightly lowered. If the amount exceeds 25 parts by weight, the ink setting tends to be slightly deteriorated.
