Embodiment 1

[0085]

[0086] The weight per unit area is 77g / m 2 , Density 0.77g / cm 3 On high-quality paper, use an air knife coater to achieve a dry solid content of 10g / m 2 The following compressive layer coating liquid 1 was applied and dried in the manner described above, whereby a support 1 was obtained. Coating conditions and drying conditions are adjusted to obtain a predetermined compressibility.

[0087]

[0088] 100 parts of light calcium carbonate (Tamapearl TP-121: manufactured by Okutama Industry Co., Ltd.), 3 parts of starch (MS4600: manufactured by Nippon Food Chemicals Corporation), 7 parts of styrene-butadiene-based binder (E1585: manufactured by Asahi Kasei Chemicals Corporation) Water was added so that the concentration of the coating solution would become 40%, and the mixture was dispersed and mixed with a mixer to prepare a compression layer coating solution 1.

[0089]

[0090] 300 parts of water-soluble polyester-based binder (Plascoat RZ-142, glass transiti...

Embodiment 2

[0099] In Example 1, except having changed the compressive layer coating liquid 1 into the following compressive layer coating liquid 2, it carried out similarly to Example 1, and the to-be-printed object of Example 2 was obtained.

[0100]

[0101] 80 parts of light calcium carbonate (Tamapearl TP-121: manufactured by Okutama Industry Co., Ltd.), 20 parts of synthetic amorphous silica (Finesil X60: manufactured by Oriental Silicas Corporation), and 3 parts of starch (MS4600: manufactured by Nippon Food & Chemical Industry Co., Ltd.) 7 parts of styrene-butadiene-based binder (E1585: manufactured by Asahi Kasei Chemicals Corporation) were added with water so that the concentration of the coating solution became 35%, and dispersed and mixed with a mixer to prepare a compression layer coating solution 2.

Embodiment 3

[0103] In Example 1, except having changed the compression layer coating liquid 1 into the following compression layer coating liquid 3, it carried out similarly to Example 1, and the to-be-printed object of Example 3 was obtained.

[0104]

[0105] 50 parts of light calcium carbonate (Tamapearl TP-121: manufactured by Okutama Industry Co., Ltd.), 25 parts of synthetic amorphous silica (Finesil X60: manufactured by Oriental Silicas Corporation), hollow plastic pigment (ROPAQUE HP91: manufactured by Dow Coating Materials Co., Ltd. 25 parts of starch (MS4600: manufactured by Nippon Food Chemicals Co., Ltd.), 7 parts of styrene-butadiene-based binder (E1585: manufactured by Asahi Kasei Chemicals Corporation) Add water so that the concentration of the coating solution becomes 30%, and use a mixer Disperse and mix to prepare a compression layer coating liquid 3.

Abstract

The present invention provides printing paper used in a paper printing method in which it is possible to form a fine image on an article to be subjected to printing, good color development is obtained, and moreover, good adhesion between printing paper and an article to be subjected to printing is obtained. The present invention is achieved by printing paper characterized by including a support body and a paste layer on the surface of the support body, wherein the support body has a compression layer containing at least pigment and binder on at least the side on which the paste layer is provided, and has a compression ratio of 1.5 or more, the compression ratio being calculated from the smoothness that is based on JIS P 8151:2004 and that is measured under a condition in which air supply pressures to a clamp are 300 kPa and 2000 kPa, and a soft backing is used, by using the following expression: compression ratio=[smoothness of the support body at 300 kPa] / [smoothness of the support body at 2000 kPa].

Description

technical field [0001] The present invention relates to a printing paper used for transferring a pattern by a printing printing method for forming a pattern on a printed material such as a fiber material or a leather material. In particular, it relates to printing and dyeing paper used in paper printing and dyeing. Background technique [0002] As a method of firmly and finely forming a pattern with a dye on a fiber material or a leather material, there is a printing and dyeing printing method. Dyeing and printing methods are roughly divided into plate-making printing methods that use plate-making and non-plate-making printing methods that do not use plate-making. [0003] As a printing method based on a plate printing method, screen printing, roll printing, rotary screen printing, gravure printing, or a method utilizing these printing techniques are known, and are already practiced industrially. However, in the printing and dyeing printing of the plate-making printing met...
