Abstract

PURPOSE:To enhance image properties, in the title tissue paper as a porous support used in a thermal head, by specifying an average aperture area, the standard deviation of an aperture area and an aperture ratio. CONSTITUTION:A fiber with an average fiber diameter of about 2-12.0mum and a length of about 2-5mm finer than a general-purpose natural fiber, a synthetic fiber and a regenerated fiber, pref., a regenerated fiber of Manila hemp is dispersed in water independently or dispersed in water to be mixed with a general-purpose fiber to form tissue paper with a basis wt. of about 5-15g/m<2>, a thickness of about 10-50mum and a density of about 0.25-0.45g/cm<3> by a papermaking process. The average aperture area of this tissue paper is set to 600-1400mum<2>, the standard deviation of the aperture area thereof is set to 1800mum<2> or less and the aperture ratio thereof is set to 15-40%. That is, when the average aperture area is too large, the way to issue of ink is non-uniform and, when the average aperture area is too small, missing dots are generated. When the aperture ratio is too large, ink is excessively issued locally and, when the aperture ratio is too small, the passage property of ink lowers.

The thin paper according to the prior art has the following problems. That is, since the opening area is large and the variation is large, the ink permeability is non-uniform, and the area where the ink is overprinted is set back (ink is printed on the back of the printed matter that is overlaid), and no ink is printed. A clear image cannot be obtained because the spots are white or dull. Japanese Patent Laid-Open No. 61-53092, which defines the opening ratio of thin paper.
In the case of the publication, it is effective for the perforability of the film,
Ink permeability is insufficient. Furthermore, JP-A-2
In the case of Japanese Patent No. 30593, the open area ratio, the average open area, and the compression work amount are specified, but the average open area is too large to satisfy the ink permeability.

In the present invention, the basis weight of the thin paper made into paper is 5 to 1

As described above, in order to uniformly extrude the ink through the holes of the film within the preferable basis weight and thickness range, a fine fiber (preferably 2 to 5 mm) having a preferable length (average fiber diameter of 2 to 12 μm) is used. By increasing the number of fibers used and dispersing the fibers uniformly, the voids of the thin paper can be appropriately subdivided, and the voids can be made as uniform as possible. Specifically, the average open area is 600-

If the average opening area is larger than 1,400 μm 2 , the ink is not evenly ejected, and an image missing portion or an unclear portion is generated. On the other hand, if it is less than 600 μm 2 , poor fiber dispersion occurs and white spots occur due to fiber flocs. Further, when the porosity exceeds 40%, the ink locally comes out excessively, and when viewed as a whole, it is not preferable because the dot connection of the characters is poor and the resolution is poor, and white spots in solid areas occur. If the porosity is lower than 15%, the ink permeability is poor, the dot connection of characters is poor, the resolution is poor, and white spots in solid areas are likely to occur, which is not preferable. In addition, the opening of the porous thin paper in the present invention is a portion where it seems that light is transmitted and forms a hole, and is a planar analysis of the hole through which the ink passes.
