た。As this type of transfer foil, a mat layer (matte layer) is provided on a release layer of a base material sheet, and the matte surface is transferred by transferring the rough surface state of the mat layer to the surface of the transfer object. Although there is a method of providing such a transfer foil,
The mat layer is composed of melamine resin, for example, about 200 ° C
A high-temperature baking treatment of passing through a hot air dryer for 5 to 10 seconds to cure the resin and form a layer (Japanese Patent Application Laid-Open Nos. 62-18298 and 62-44491). It has been known. However, this manufacturing method has a problem in that the transfer foil obtained by the high heat during the baking process tends to be distorted. A method of forming the mat layer using a thermosetting resin of a solvent-soluble type is also known, but a manufacturing method using such a resin material or a manufacturing method using a general-purpose thermosetting resin is also known. In case of high temperature for curing (150 ~ 170
C) and a heating time (10 to 30 minutes), so that the curing is unstable, or there is a disadvantage that the transfer foil is distorted by the heat during the heating and curing. Moreover, the thermosetting resin as described above cannot be applied to a coater or the like that needs to be cured in 10 to 30 seconds, or an unreacted functional group remains even though it seems to be dried and cured in appearance. Therefore, there was a problem that the mat layer adhered to the release layer. Further, there is a production method in which a release layer is formed of a melamine resin together with a mat layer. However, in this case, there is a problem that the obtained transfer foil cannot be used as a transfer foil for simultaneous transfer by injection molding.

A transfer foil that shapes and forms a matte part to adjust the glossiness of the transfer layer, and a transfer foil that uses two types of transfer foil to form a complex pattern with different gloss and color on the surface of the transfer target are proposed. However, these materials require a separate gloss adjusting material or two types of transfer foils, and only after-transfer must be performed on the matte part. There was a problem such as cost.
