Description of the Related Art Hitherto, it has been generally difficult to obtain strong interlayer adhesion when laminating a layer made of an ionizing radiation-curable resin on another substrate. Therefore, the curing of the ionizing radiation-curable resin layer during the processing of the ionizing radiation-curable resin layer is controlled to an incomplete state, and after processing the next layer such as an adhesive layer, a method of completely curing with ionizing radiation again or a tacky adhesive is used. Methods for obtaining adhesion with an ionizing radiation-curable resin layer and the like have been performed. Recently, a first intermediate layer made of a polyurethane resin, an acrylic resin and an isocyanate is provided between an ionizing radiation-curable resin and an adhesive layer, and a second intermediate layer made of an acrylic resin is provided next. A method for obtaining the adhesion between the cured resin layer and the adhesive layer has been proposed.

When the average particle size exceeds 500 nm, the transmittance tends to be impaired,
If it is less than 1 nm, the effect of preventing interference becomes extremely small. As the fine particles (3), inorganic oxide fine particles dispersed in a colloidal form are preferable, and as the inorganic oxide fine particles, silicon oxide, antimony oxide, tin oxide, indium oxide, zinc oxide, alumina, titania, zirconia and the like can be mentioned. In particular, considering the price and color, silicon oxide,
For example, colloidal silica is preferable. It is more preferable that these fine particles (3) are treated with a coupling agent such as acryloxy-functional silane or the like and then subjected to acrylate modification so as to be crosslinked with ionizing radiation, and then mixed with the ionizing radiation-curable resin. Since the surface acrylated inorganic oxide fine particles participate in the crosslinking with the ionizing radiation-curable resin, even if they are blended in a large amount, the hardness does not decrease and the hardness tends to increase. In addition, mixing is easy without the need for a step of dispersing the resin in the ionizing radiation-curable resin, and the transparency after mixing is excellent. Inorganic oxide fine particles subjected to acrylate surface treatment and fine particles not subjected to acrylate surface treatment may be used in combination.

生や逆に硬化不良が生じるなど好ましくない。According to the present invention, as described above, the particles (2) and the fine particles (3) are contained in the hard coat layer (5), whereby the density of the particles is increased at the expense of transparency, and the occurrence of interference is suppressed. (This caused the haze to rise and the screen became very difficult to see.) The problem of the conventional technology was solved, and the occurrence of interference was suppressed, and an antiglare hard coat layer having a haze of 30% or less was obtained. It is something that can be done. In the present invention, an antiglare hard coat layer having sufficient suppression of the occurrence of interference and a haze of 20% or less, and more preferably 10% or less is obtained. The amount of the particles (2) imparting antiglare properties is affected by the specific gravity of the particles (2) used, but is usually 0.05 to 30% by weight based on the solid content of the ionizing radiation-curable resin (4). Preferably it is in the range of 0.2 to 5% by weight. The added amount of the fine particles (3) is 0.001 of the solid content of the ionizing radiation-curable resin (4).
To 80% by weight, preferably 0.2 to 40% by weight. The thickness of the hard coat layer (5) is not particularly limited, and is usually selected as appropriate from a range of about 1.0 to 10 μm. If the thickness is less than 1.0 μm, it is difficult to cure, which is not preferable. On the other hand, when the thickness exceeds 10 μm, cracks in the coating film occur, and conversely, poor curing occurs.

る。The intermediate layer (6) in the anti-glare surface protective transfer material of the present invention comprises a gravure printing method, a screen printing method, and a coating method in which a mixture of butyral resin and isocyanate is dissolved in an organic solvent. It is formed by applying, drying and forming on the hard coat layer (5) by a normal printing method such as an offset printing method. The degree of polymerization of the butyral resin is not particularly limited, but is preferably about 800 to 2,000. Butler
The mixing ratio of the resin to the isocyanate is 98: 2 to 5
A range of 0:50 is preferred. If the ratio of the isocyanate is 2 or less or the ratio of the butyral resin is 50 or less, it is difficult to obtain strong adhesion to the hard coat layer (5). In the present invention, the intermediate layer may be the above-mentioned one intermediate layer, but it is more preferable to further provide a second intermediate layer on the intermediate layer. The second intermediate layer preferably contains butyral resin as a main component. For example, a gravure printing method, a screen printing method, an offset printing method or the like is obtained by dissolving the above-mentioned butyral resin alone in an organic solvent. Formed on the intermediate layer (6) by the ordinary printing method described above.

かつ防眩効果をも有したものである。The adhesive layer (7) used in the anti-glare surface protective transfer material of the present invention is formed by coating a coating material obtained by dissolving an adhesive resin in an organic solvent by a usual printing method such as a gravure printing method, a screen printing method and an offset printing method. It is formed by applying and drying on an intermediate layer by a method. The adhesive resin used for the adhesive layer (7) used in the antiglare surface protection transfer material of the present invention is not particularly limited, and may be appropriately selected from resins used for ordinary transfer materials. For example, acrylic, vinyl acetate, vinyl chloride, styrene butadiene, vinyl chloride-vinyl acetate, ethylene-vinyl acetate, polyester, chloride rubber, chlorinated polypropylene,
The resin is appropriately selected from emulsion resins, organic solvent resins, and water-soluble resins containing a urethane-based resin alone or a mixture thereof as a main component. The adhesive layer (7) is formed by applying a coating liquid obtained by diluting the resin with water or an organic solvent to an intermediate layer (6) by a gravure printing method, a screen printing method, or an offset printing method.
Alternatively, it is formed by applying and drying on a second intermediate layer, a printing layer, a coloring layer, or the like added as necessary. The thickness of the adhesive layer is not particularly limited, and is usually appropriately selected and adopted from a range of about 0.3 to 20 μm according to the surface condition of the transfer object. The anti-glare surface protective transfer material thus obtained has all the problems of the conventional surface protective transfer material having an ionizing radiation-curable resin layer, namely, interlayer adhesion, appearance, workability, and post-transfer resistance. By solving all of the above problems, it is excellent in scratch resistance, stain resistance, solvent resistance, water resistance, etc. and also has an antiglare effect.

When the reflection of the light source by visual judgment is measured, the first embodiment is explained. Both of the examples 2 were excellent in anti-glare properties with almost no reflection of the light source, but the comparative examples had a problem in the anti-glare property in which reflection of the light source was observed.
