JPH0199898A - Transfer foil imparting brightness by condensing - Google Patents

Abstract

PURPOSE: To give the brightening property by converging to an edge part of a member to be transferred by forming a colour layer provided with a converging property on one face of a base through a separating layer when necessary, forming an adhesive layer on the color layer, and transferring the same onto the transparent member to be transferred. CONSTITUTION: The desired transferring is performed onto various kinds of transparent members to be transferred such as plastic or the like by the marking, the rubber pressing, the roller pressing or the like, and then a base 10 is separated to transfer the color layer 30 provided with the converging property onto the member to be transferred. In the case when the transferring is performed to the entire face of, e.g. a plastic face plate 50, the generated light is repeatedly reflected to be emphasized along an interface, and the light is converged on the edge part, differently from that comprising the fluorescent property and the light accumulation property, because the face plate 50 is provided with the color layer 30 comprising the converging property on the surface. As a result, the edge part looks like particularly having the brightening property by the converging.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a transfer foil, and more particularly to a transfer foil that can be given glitter by condensing light.

(Prior art and its problems) Transfer foils have various colors and glosses, but in the past, most of the colors and glosses were flat and uniform, with little variation, and multicolor printing was not possible. Even with the transfer foil, the printed design etc. is transferred as is after the transfer, and the color or gloss that has changed in particular does not appear after the transfer.

This invention is completely different from conventional ones.At the same time, the desired transfer is performed on a transparent object, and at the same time, the edge of the transferred object has a particularly glittering property due to light condensation. This provides a transfer foil that appears to have glitter only at the edges.

(Means for Solving the Problems) This invention provides a colored layer provided with light-concentrating properties on one side of a base material, if necessary via a release layer, and an adhesive layer provided on the colored layer. This transfer foil is characterized in that, after being transferred onto a transparent transfer object, glitter can be imparted to the edge of the transfer object by condensing light.

Next, this invention will be explained with reference to the drawings.

As the base material 10, materials conventionally used for transfer foils, such as various plastic films, can be used. When the base material 10 has releasability, it can be used as it is, and when the base material 10 does not have releasability, it can be used after forming a release layer 20@Colored layer 30 with light-gathering properties The base material 10 is provided by applying a paint mixed with a light-harvesting dye or an organic pigment, or a paint in which a resin previously imparted with light-harvesting properties is dissolved, onto one side of the base material 10.

The thickness of the colored layer 30 is 0.5 to 50 .mu.m, and 3 to 10 .mu.m is particularly preferable in consideration of both production and post-transfer effects. If the colored layer 30 is thin (0.5 μm), it will be too thin and condensing light will be difficult to notice, and if it is thicker than 50 μm, it will be too thick.
0 cannot be easily formed.

The colored layer 50 may contain glass beads, colloidal silica, mica, microcapsules, kaolin, bentonite, titanium oxide, surface-treated titanium oxide particles, etc. as a filler, and also transparent fireflies. It may also contain photodyes and fluorescent pigments.

Further, the colored layer 30 may have a pattern by arbitrarily forming appropriate cracks. In this way, the crack portion also becomes an end portion, so to speak, and appears to have particularly glittering properties after transfer.

The colored layer 30 may be provided with a transparent resin layer having a relatively low refractive index thereon.
This ff1lllK is of course included in this ff1lllK.

The adhesive layer 40 is provided on the colored layer 30 using an appropriate resin such as acrylic resin or epoxy resin.

(Function) This invention performs the desired transfer onto various transparent materials such as plastics by stamping, rubber pressing, roll pressing, etc., and then peels off the base material to form a colored layer with light-concentrating properties. is transferred to the transfer target.

For example, in the case where the entire surface is transferred to a plastic nameplate 50, the nameplate 50 has a colored layer 30 with light-gathering properties on its surface, which has fluorescent and luminescent properties. Unlike the attached light, the emitted light is repeatedly reflected along the interface and is emphasized, so the light is focused at the edge. As a result, the end portions have a particularly glittering property due to the convergence of light, and when viewed, it appears that only the end portions have a glittering property. Note that the edge of the transparent transfer object may be at a right angle to the plane, but if it forms an angle other than a right angle, the edge will appear wide when the transfer object is viewed from the plane side. Therefore, it appears to have a wide range of glitter properties.

(Example) A release layer was provided on one side of a PET film with a thickness of 0.025 snr using a paint with the following composition, and on the release layer a paint with the following composition in which a yellow light-harvesting dye was dissolved was applied to a thickness of 5 μm. The transfer foil of the present invention was obtained by applying a colored layer by coating it so as to give the same color, and then forming an adhesive layer on the colored layer using a paint having the following composition.

Using the transfer foil obtained as described above, it was transferred onto a transparent polycarbonate name plate with a thickness of 0.5 ff using a single loop. As shown in FIG. 2, the nameplate obtained in this way had particularly glittering properties at the edges, and was shining in the color of moonlight.

(Effects of the Invention) Since the transfer foil of the present invention has a colored layer imparted with light-gathering properties, after being transferred to a transparent transfer object, the edges of the transfer object become particularly shiny due to light condensation. - Since it appears to have glitter only at the edges, it can bring about a unique decorative effect of color and luster that cannot be seen in conventional transfer foils. .
