が起って不溶化することをいう。A photosensitive resin is applied to the surface of the iron roll 1 by spraying, for example, to form a photosensitive resin layer 1 as shown in FIG. Conventionally known photosensitive resins can be used. Next, prebaking is performed at 60 to 80°C for 15 to 30 minutes to dry the photosensitive resin layer. Next, a negative film 8 is brought into close contact with the surface of the photosensitive resin layer 10, and the rear side of the negative film 8 is irradiated with light, for example, ultraviolet rays 9, as shown in FIG. 2 to perform printing. A predetermined pattern is formed on the negative film 8 as a positive image. In this baking step, the portion of the photosensitive resin layer a1 in contact with the negative film portion 8a through which the ultraviolet rays 9 have passed, is in other words, the ultraviolet rays II! ! The photosensitive resin layer portion 7a exposed to UV 90 is cured, thereby forming a cured resin layer A in the photosensitive area, while the photosensitive resin layer portion 1b1 in contact with the negative film portion 8b through which UV 9 does not pass, in other words, UV 9 The portions of the photosensitive resin layer B that are not exposed to the light are not cured, and an uncured resin layer B is formed in the unexposed portions.

粒子堆積層２ａを形成する。After the baking is completed, the negative film 8 is removed, and the iron roll having the cured and uncured resin layer AXB is immersed in a developer.
Perform development. In this development process, the uncured resin layer B is dissolved in the developer and removed, and the cured resin layer A remains undissolved, so that as shown in FIG. is formed on the surface of the iron roll 1. Next, metal powder spraying is performed to form a metal particle deposit layer on the iron roll base 1a exposed between the cured resin layers A. In the metal powder spraying, for example, nickel powder is 90% by weight.
When using a mixed powder consisting of aluminum powder and aluminum powder, pure nickel produced by the thermite reaction does not adhere to the surface of the cured resin layer due to its nature. Therefore, the recesses on the surface of the iron roll 1 are filled with nickel particles. (Fig. 5) To explain this metal powder spraying process in detail, first, an iron roll 1 is rotatably supported on a suitable support member, and a metal powder spraying device is installed opposite the iron roll 1 so as to be movable in the horizontal direction. . Then, in the metal powder spraying apparatus, a mixed powder consisting of, for example, 90×t of nickel powder and 10×t of aluminum powder is supplied to an acetylene frame at 2800° C. At this point, the mixed powder melts and the aluminum removes oxygen from the nickel oxide film (thermite reaction), turning the nickel into highly pure nickel. The pure nickel is blown away in the form of molten particles by the force of the flame and adheres to the iron roll 1a, forming a nickel particle deposit layer 2a.

るニッケル粒子の高さを高くすることができる。The thermal spraying process is performed while moving the metal powder spraying device horizontally and rotating the iron roll 1.
The nickel particle deposit layer 2a can be evenly formed on the iron roll base 1a which is sprayed out between the hardened resin on the surface. Further, by repeating the above-described blasting nine times, the height of the nickel particles deposited on the iron roll base 1a can be increased.

、多層構造となしてもよい。After the metal powder spraying process is completed, the cured resin layer A is cooled and then dissolved and removed using a solvent (for example, methyl ethyl ketone) to form a nickel particle deposited layer, which remains as a multi-curved layer, as shown in Figure 6. As a result, an uneven pattern 10 is formed on the surface of the iron roll 1, and an embossing roll number having such an uneven pattern 10 can be obtained, but the present invention is not limited to the above embodiment. For example, metal particles such as brass or tungsten carbide may be further deposited on the nickel particle deposited layer by thermal spraying with gold metal powder to form a multilayer structure.
