Definitions
- the present invention relates to a coated paper for printing, and more particularly, to a coated paper for printing which is bulky (low density), has excellent flexibility, and has good workability in a printing machine.
- the present invention relates to a coated paper for printing, which is bulky (low density), excellent in flexibility and low in glossiness of blank paper, but has high printing glossiness in the image area,
- the present invention relates to a matte coated paper which has a small amount of fine gloss unevenness and good workability in a printing press.
- Examples of papermaking pulp include chemical pulp obtained by extracting lignin in fibers with chemicals, groundwood pulp obtained by grinding wood with a grinder without using chemicals, and thermomechanical pulp obtained by disintegrating wood with a refiner Mechanical pulp.
- mechanical pulp has more rigid fibers than chemical pulp and is more effective in increasing bulk (low density).
- these mechanical pulp have problems such as a decrease in whiteness, and even with medium quality paper, printing defects such as paper waste due to binding fibers are likely to occur.
- waste paper pulp is increasingly being combined.
- wastepaper pulp is generally pulped with a mixture of high-quality paper, newspaper, magazines, coated paper, etc., and is therefore compared to virgin (unused paper pulp) mechanical pulp. High density and not bulky.
- Japanese Patent Application Laid-Open No. 5-339898 discloses a method of reducing the density by blending hollow synthetic organic substance capsules. .
- synthetic organic substances lower the paper strength, causing problems such as paper breakage during printing, and also require high blending to obtain a sufficient bulking effect, resulting in high production costs.
- JP-A-52-74001 proposes a method using a shirasu balloon. I have.
- this method has poor mixing properties with papermaking pulp, and also has problems such as uneven printing on paper containing the pulp. As described above, it has not been possible to impart flexibility to paper even with the above-described method.
- the coating layer of the coated paper is generally higher in density than the base paper. Therefore, the density of the coated paper is higher than that of the printing paper having no coating layer. In order to increase the bulk of the coated paper, it is also achieved by reducing the coating amount of the coating composition. This is because the ratio of the coating layer in the entire coated paper becomes small. However, reducing the number of coating layers simultaneously reduces the coatability of the base paper with the coating layers, lowering the print quality such as white paper gloss, smoothness, and print gloss. There was a limit to reducing the coating amount while holding.
- print lightness In order to improve the print quality of coated paper, especially the ink deposit density and the glossiness of the image area (hereinafter referred to as “print lightness”), it is an effective means to improve the smoothness of the coated paper.
- a surface smoothing process such as Super Calender / Soft Nip Calendar
- these treatments increase the smoothness of the surface by applying pressure to the paper.
- the thickness of the paper is reduced, and there may be cases where sufficient bulkiness cannot be achieved to obtain the target print quality. there were.
- the general method of producing matte coated paper is mainly to suppress the glossiness of white paper, and pigments with a large average particle diameter have been used in paints.
- 30 parts by weight of the pigment in the paint is escalon 150 (heavy calcium carbonate) of heavy calcium carbonate (average particle diameter 1.65).
- escalon 150 heavy calcium carbonate
- dull coated paper is generally a matte-coated paper that has been subjected to a mild surface treatment, and provides higher printing gloss than a matte-coated paper. mark
- it is necessary to enhance the surface treatment conditions, and it was difficult to maintain the low-density paper volume due to low density, as with matte-coated paper.
- the glossiness of a sheet of white paper can be reduced.
- the density is increased and the bulk is lost, so that the target bulky matte coated paper cannot be obtained.
- a calendar using a combination of a metal roll and a resin roll having a rough surface roughness As a method of improving the printing glossiness while keeping the density low and suppressing the white paper glossiness low, there is a use of a calendar using a combination of a metal roll and a resin roll having a rough surface roughness.
- a metal roll having a rough surface As disclosed in JP-A-6-73685, JP-A-6-73686, JP-A-6-73697, and JP-A-7-238493, treatment using a metal roll having a rough surface is performed. Surface treatment is performed at a temperature of 100 ° C or higher.
- the present invention is bulky (low-density), yet excellent in flexibility, excellent in workability in a printing press, and furthermore, despite the low glossiness of blank paper, the image area
- An object of the present invention is to provide a coated paper for printing which has high print gloss and print quality with little minute gloss unevenness in the image area. Disclosure of the invention
- the present inventors have conducted intensive studies in such difficult situations as described above, and as a result, in a printing coated paper having a coating layer containing a pigment and an adhesive on a base paper, the basis weight, density, 4's of the product of breaking length of the paper direction Young's modulus ⁇ Pi machine direction is 1. 0 X 1 0 21 g 2 ⁇ NZm 6 or 4. 0 X 10 21 g 2 ⁇ NZm 6 or less, more preferably 2 - by 0 X 10 21 g 2 ⁇ NZm 6 or 3.
- the present inventors paid attention to the ease of turning a booklet when examining the flexibility of paper.
- the stiffness of paper is quantitatively evaluated by stiffness of Clark, stiffness of pure bending, and the like.
- stiffness of Clark As a result of investigating the correlation between the ease of page turning by the subject and the pure bending stiffness in the papermaking direction and width direction for various booklets, paper with low stiffness tended to be flexible, but even if stiffness was the same.
- the paper As the page is turned, the paper is subjected to bending stress, with tensile stress on the convex surface and compressive stress on the concave surface. Therefore, the correlation between the Young's modulus in the width direction and the papermaking direction and the ease of turning was determined. As a result, it was confirmed that even when the pure bending stiffness in the width direction was the same, the lower the Young's modulus in the width direction and the papermaking direction, the easier the pages were turned.
- the present inventors also investigated the relationship between paper strength and flexibility. As a result, it was found that when the thickness of the paper was compared, paper with a shorter tear length tended to have higher flexibility. For example, in the case of paper with a long tear length, the amount of hydrogen bonds formed between the pulp fibers in the paper is large, and the paper strength tends to be relatively strong. It is considered that the bending stress or tensile stress required to obtain the same bending strain or tensile strain becomes relatively large, which makes it difficult to turn the page.
- 4's product is 1. 0 X 1 0 21 g 2 ⁇ N / m 6 or 4. 0 X 1 0 21 g 2 ⁇ N / m 6 or less, preferably 2. 0 X 10 21 g 2 ⁇ N / m if 6 or more 3.
- paper with a normal density and a product of four products of less than 1.0 x 10 21 g 2 • NZm 6 has an excessively low Young's modulus or a tear length. This is low, and the paper is too flexible, making it difficult to turn pages because of paper stiffness, or increasing the paper strain due to the tension in the printing press, and the paper stretched beyond the elastic limit will be ruptured. , Paper break is easy to occur. Also in comparison with the same basis weight, the sheet catcher's modulus ⁇ Pi breaking length is a value of 4's product in the usual value 1.
- the glossiness of the blank paper aimed at in the present invention is low. No glossy coated paper with high print gloss (gloss of the image area of the printed matter) and good fine gloss unevenness (print surface feeling) of the image area was obtained.
- the present inventors have conducted intensive studies on the coating composition. As a result, they have found that the distribution of the particle diameter of the pigment particles is narrow, that is, by narrowing the particle size distribution, the coatability of the base paper with the coating layer is improved.
- general inorganic pigments for coating compositions do not have a substantially uniform particle size like organic synthetic particles, for example, plastic pigments, but are mixed with fine particles and coarse particles. Wide particle size distribution.
- the packing ratio of the particles is the same regardless of the particle size, but polydispersion, for example, in a mixed system of spheres having two different particle sizes, The packing density of particles depends on the ratio of large to small particles, the mixing ratio of two types of particles, etc., and the ratio of particle diameters (particle size of small particles Z value of large particles) The smaller the value, the higher the filling rate.
- a coating layer composed of a pigment having a narrow particle size distribution has a larger particle size or a smaller particle size of a large particle than a pigment having a wide particle size distribution, or the filling rate of the pigment particles is increased due to both effects. It was considered that the density of the coating layer became low.
- coated paper increasing the amount of coating is effective to improve the coverage of the base paper with the coating layer.However, when the target is a bulky coated paper, the density is lower than that of the base paper. Increasing the proportion of the coating layer having a high density increases the density of the coated paper and is not suitable. In order to improve the smoothness of the base paper by the coating layer as compared with the same coating amount, it is necessary to reduce the density of the coating layer. Therefore, in a coating layer which is a mixture of particles having a large number of particle diameters, lowering the filling rate of the pigment particles lowers the density of the coating layer and improves the coatability of the base paper. Conceivable.

- the coatability of the base paper by the coating layer is greatly improved. 20 parts or more, more preferably 50 parts or more, and more preferably 50 parts or more, of a force-olin having a particle size distribution in a range of 0.4 to 4.2 ⁇ in the coating layer in an amount of 65% or more.
- the pigment in the coating composition contains less than 65% of particles that fall within the range of 0.4 to 4.2 / zra by volume and contains many small particles, the packing density of the particles In addition, these particles enter the minute gaps on the base paper surface and do not remain on the base paper surface layer, so the base paper coverage is poor, the print gloss is low, and the fine gloss unevenness is large. Feeling inferior.
