Abstract

PURPOSE:To impart gloss and smoothness to a transfer surface by successively laminating a release layer, a transfer surface smoothing resin layer, a decorative layer and an adhesive layer on a support sheet in specific order as a transfer layer and making the glass transition point of the transfer surface smoothing resin layer lower than that of other any layers. CONSTITUTION:A transfer sheet is obtained by successively laminating a release layer 3, a decorative layer 4, a transfer surface smoothing resin layer 5 and an adhesive layer 6 to the single surface of a support sheet. In this case, the decorative layer 4 and the transfer surface smoothing resin layer 5 may be replaced. Otherwise, the release layer 3, the transfer surface smoothing resin layer 5, the decorative layer 4, the transfer surface smoothing resin layer 5 and the adhesive layer 6 are successively laminated to the single surface of the support sheet 2. The support sheet 2 to be used has smoothness and the release layer 3 facilitates the release of the support sheet 2 and becomes a surface protecting layer after transfer. The decorative layer 4 has a pattern such as a figure, a mark, a character or a color layer. The transfer surface smoothing resin layer 5 prevents the unevenness of a transfer surface and Tg thereof is made lower than that of other layers.

2. Description of the Related Art Conventionally, in a molded product or the like used in a light electric appliance, a cosmetic container, a building material member, etc., a transfer sheet having a desired design and a decorative layer is formed on the surface of the transfer sheet. It is used as a means for easily improving the design of the product surface by transferring the decorative layer.
Conventionally, the transfer sheet has a structure in which a transfer layer including a release layer, a decorative layer such as a picture pattern, and an adhesive layer is laminated on the surface of a releasable support sheet. However, in the above-mentioned conventional transfer sheet, when the transfer sheet was transferred to a product, the protrusion of the decorative layer caused minute unevenness on the transfer surface, and the gloss was impaired. Therefore, in order to eliminate the unevenness after the transfer, the transfer surface is coated with a transparent paint, or pressed.

The transfer surface smoothing resin layer 5 of the transfer sheet of the present invention is a layer for preventing unevenness of the transfer surface, and is made of, for example, polyester resin, vinyl chloride resin, vinyl acetate resin, acrylic resin, cellulose resin or the like. A material having a Tg lower than that of the decorative layer is selected. Further, considering the preferable embodiments of the release layer and the adhesive layer as described above and below, the Tg of the transfer surface smoothing resin layer is set to be lower than the Tg of the decorative layer, the release layer, and the adhesive layer. Moreover, it is sufficient that it has appropriate adhesion to the peeling layer and the decorative layer. If necessary, the transfer surface smoothing resin layer may be colored by adding a raw material or a dye. Further, by using a thermosetting resin or an ionizing radiation-curable resin for the transfer surface smoothing resin layer, it is possible to absorb minute irregularities of the decorative layer with a low melting point during transfer, so that the surface smoothness is excellent. A transfer product is obtained. Further, it is possible to improve adhesion and physical properties by curing after transfer. The transfer surface smoothing resin layer is laminated by a printing method such as a gravure method, a screen method and an offset method. The thickness of the transfer surface smoothing resin layer is 0.5 to 6 μm, preferably 1 to 3 μm.
If it is 0.5 μm or less, the effect of smoothing the transfer surface is small, and if it is 6 μm or more, the effect of smoothing the transfer surface is obtained, but the cost is increased.
