Description

[Detailed explanation of the idea]

The present invention relates to a transfer foil, particularly a transfer foil using a metallic pigment. For example, when making a decorative material using a metallic transfer foil, if the luster of the metallic foil can be varied depending on the part, a highly designed decorative material can be obtained. The inventor of the present invention focused on the fact that the gloss exhibited by metallic pigments varies depending on the particle size of the same pigment, and particles with a small average particle size have lower gloss than those with a large average particle size. We succeeded in obtaining a metallic foil with different colors depending on the area. As shown in FIG. 1, the transfer foil of the present invention has a transfer foil 1 comprising a base film 3, a release layer 4, a metal powder ink layer 5, a filler layer 6, and an adhesive layer 8. A part of the layer 51 of the powder ink layer 5 is thinner than the other part of the layer 52 and is made of metal powder ink with a small average particle size. Transfer foil with different metallic luster. In the thin layer 51, not only the gloss is low but also the hiding property is poor, so that an anti-metallic color is obtained due to the pigment ink of the filling layer 6 or the hiding layer 7 serving as the base layer. In this way, a highly designed transfer foil is obtained in which the metallic color of the other layer 52 with high gloss is combined with the anti-metallic color of the thin layer 51 with poor gloss. As the base film 3, when a matte surface is desired, a matte film kneaded with fine silica powder, typically a polyester film, is used, and when a glossy surface is desired, an ordinary smooth film is used. Use. The material and thickness of each of the layers sequentially provided on the base film may be determined according to techniques known in the field of transfer foils, except for the metal powder ink layer. Although the means of application is arbitrary, it would be appropriate to perform solid printing by gravure printing. For the metal powder ink layer, aluminum powder with a wide range of particle sizes, for example, aluminum powder with a particle size of 15 to 40 microns, is used. When printing this, if you use a gravure plate with different plate depths depending on the part, powder with small particle size will collect in the shallow part, and other powder will remain in the deeper part, so depending on the shallow depth of the plate. The average particle size of the metal powder can be varied. That is, in the transfer foil 1, relatively small-diameter metal powder gathers in the thin part 51 of the metal powder ink layer 5, and relatively large-diameter metal powder gathers in the thick part 52. This effect can be ensured by selecting the shallower plate depth to be less than the maximum grain size of the above grain size distribution, in particular to 2/3 or less. Of course, the deeper plate depth should be equal to or greater than the maximum grain size. For the above particle size distribution,
For example, the shallower one is 25μ and the deeper one is 40μ. The filling layer 6 may be printed with ink containing any pigment in order to compensate for the difference in thickness of the metal powder ink layer and to provide an anti-metallic design as a base layer. If necessary, between the filling layer 6 and the adhesive layer 8,
A concealing layer 7 is provided with ink using an appropriate pigment. An example of the above configuration is as follows.

[Table] Le series
FIG. 2 shows how the transfer foil of the present invention is transferred onto the object 10 to be transferred. With the above-described configuration, the part 51 where the metal powder ink layer is thin and small-diameter metal powder is gathered has low gloss, and the other part 52 where there is thick and large-diameter metal powder has high gloss. Needless to say, this pattern can be arbitrarily selected, and if desired, the degree of gloss can be divided into three or more levels, or areas where the gloss continuously decreases or discontinuously changes. As a result, a transfer foil with extremely high design properties can be obtained.
