Embodiment 1

[0192]

[0193] 100 parts by mass of acrylic urethane oligomer (trade name Art Resin UN-905, manufactured by Negami Kogyo Co., Ltd., mass average molecular weight 40,000 to 200,000, solid content 70 mass%, solvent is toluene) as curable resin, 12 parts by mass of colloidal silica A as a pigment and 3 parts by mass of a photopolymerization initiator (trade name IRGACURE 184, manufactured by BASF Corporation) were mixed to prepare a curable resin layer forming composition.

[0194] Table 1 shows the composition of the curable resin layer forming composition. In addition, the compounding quantity (content) of the curable resin, a pigment, and a photoinitiator shown in Table 1 is the quantity (mass part) in conversion of a solid content.

[0195]

[0196] A PET film (trade name Lumirror U48, manufactured by Toray Co., Ltd., 21 cm×29.7 cm, thickness 75 μm) was used as a plastic base material, and the obtained composition for forming a curable resin layer was bar-coated on the p...

Embodiment 2

[0198] Except having changed the compounding quantity of the colloidal silica A from 12 mass parts to 25 mass parts, the composition for curable resin layer formation of the composition shown in Table 1 was prepared similarly to Example 1.

[0199] A printing sheet was obtained in the same manner as in Example 1 except that the obtained curable resin layer-forming composition was used.

Embodiment 3

[0201] A curable resin layer-forming composition having a composition shown in Table 1 was prepared in the same manner as in Example 1 except that colloidal silica B was used instead of colloidal silica A.

[0202] A printing sheet was obtained in the same manner as in Example 1 except that the obtained curable resin layer-forming composition was used.

Abstract

The present invention relates to a printing sheet for lithographic printing plates, which comprises a plastic base and a curable resin layer that is laminated on at least one surface of the plastic base. The curable resin layer contains a curable resin and a pigment, and the pigment is composed of inorganic fine particles having hydrophobilized surfaces and an average particle diameter of 5-90 nm. The curable resin layer has a thickness of 0.1-15 mum. The present invention is able to provide: a printing sheet which exhibits excellent blocking resistance, printability and transparency when a lithographic printing plate is used for printing; a decorative sheet which is obtained by making a print on the printing sheet; and an adhesive decorative sheet.

Description

technical field [0001] The present invention relates to a printing sheet, a decorative sheet printed on the printing sheet, and an adhesive decorative sheet. [0002] This application claims priority based on Japanese Patent Application No. 2012-192200 for which it applied in Japan on August 31, 2012, and uses the content here. Background technique [0003] A sheet decorated by printing or the like (decorative sheet) may be bonded to the surface of a molded product to impart design properties to the molded product or to protect the surface of the molded product. [0004] An anchor coat is often formed on the surface of the sheet before printing (printing sheet) in order to improve the adhesiveness with the printing layer. [0005] However, in the case of printing a printing sheet using a lithographic printing plate, if an adhesion-promoting coating layer is formed, the printing sheet and the lithographic printing plate are easily adhered (blocking), and as a result, deinkin...
