In-mold transfer film which changes its color according to a temperature and which has a scent-emitting function and method for manufacturing same

Abstract

The present invention relates to an in-mold transfer film which comprises a release layer, a scent-emitting hard layer, a color-changing print layer and an adhesive layer formed sequentially in one direction on one side of a base layer, wherein the scent-emitting hard layer includes aromatic microcapsules, and the color-changing print layer changes its color according to the temperature. The present invention also relates to a method for manufacturing an in-mold transfer film comprising the following steps: forming a release layer on one side of a base layer; forming a scent-emitting hard layer on an upper surface of the release layer; forming a print primer layer on an upper surface of the scent-emitting hard layer; forming a color-changing print layer formed on an upper surface of the print primer layer; forming an adhesive primer layer on an upper surface of the color-changing print layer; and forming an adhesive layer on an upper surface of the adhesive primer layer. The scent-emitting hard layer is formed of a layer including scent-emitting microcapsules. The color-changing print layer is formed of a layer which changes its color according to the temperature.

Description

technical field [0001] The invention relates to an in-mold transfer film and a preparation method thereof. The above-mentioned in-mold transfer film is characterized in that it includes a hard fragrance-emitting layer containing fragrance-emitting microcapsules and a color-changing printing layer that changes color with temperature. Background technique [0002] Recently, in order to satisfy the hobbies of the younger generation who are the main consumers of electrical and electronic products, various improvements have been made not only in functionality but also in appearance, that is, color and design. However, the existing in-mold transfer film is used for decoration, which is limited to expressing colors by means of the color ink layer transferred on the surface, and cannot expect other functions, such as emitting various floral fragrances. [0003] Korean Patent Publication No. 2004-0024061 discloses an aromatic transfer film, but it is only limited to a certain coating...

However, the existing in-mold transfer film is used for decoration, which is limited to expressing colors by means of the colored ink layer transferred on the surface, and cannot expect other functions, such as emitting various floral fragrances, etc.

[0003] Korean Patent Publication No. 2004-0024061 discloses an aromatic transfer film, but it is only limited to a certain coating of fragrance in release agent, ink and binder to achieve the olfactory effect. In Korean Patent Publication No. No. 2009-0078883 also has relevant records, that is, various patterns printed on the transfer film are pressed onto the machine for transfer, but the transferred printed pattern cannot achieve the visual effect of changing color with temperature, so it is difficult to grasp the transfer. The problem of the heat state of the machine with printed patterns
