That is, a photosensitive synthetic resin layer is formed by applying a photosensitive synthetic resin to the surface of the workpiece, a positive film is closely attached to the photosensitive synthetic resin layer, and ultraviolet rays are irradiated to harden the exposed portion of the photosensitive synthetic resin layer. After that, the uncured portion of the dazzling synthetic resin layer that is not exposed to light is washed away, and then sandblasting is performed, and the surface of the workpiece other than the portion masked by the hardened portion of the photosensitive synthetic resin layer is ground. An engraving with a shape corresponding to the shape of the positive film is formed on the work surface.

) is formed. The support M(1)A is polyester-based,
This is a high-contrast plastic layer made of acrylic, styrene, vinyl, etc. that has good sandblasting properties. The photosensitive synthetic resin layer (2) is made of, for example, a photosensitive synthetic resin such as acrylic, urethane, or urethane-acrylic (including hexamer, oligomer, prepolymer, etc.), acrylic, styrene, or vinyl acetate. It is formed by applying a solution of a mixture of the photosensitive synthetic resin and the alkali-soluble synthetic resin onto the base film (1) and drying it, and the film thickness is usually about 20 to 100 μm. The mixing ratio with the synthetic resin is usually about 5:5 to 9: upper mold weight ratio, preferably about 6:4 to 8:2 weight ratio. On the photosensitive synthetic resin layer (2), there is further a photosensitive synthetic resin layer (
3) is formed. The photosensitive synthetic resin layer (3) is made of acrylic, urethane, or acrylic resin that becomes sticky when cured.
Photosensitive synthetic resins such as urethane-acrylic (Nanatsumar,
(including oligomers, prepolymers, etc.) and an alkali-soluble synthetic resin on the photosensitive synthetic resin layer (2), and the film thickness is usually about 5 to 20 μm. The mixing ratio of the resin and the alkali-soluble synthetic resin is usually about 5:5 to 9:1 by weight, preferably about 6:4 to 8:2 by weight. The surface of the photosensitive synthetic resin layer (3) is coated with a protective film (4) having release properties such as polyethylene, polypropylene, polyester, release paper, etc.
) is coated.
