Abstract

PURPOSE: To expand the whole picture design pattern to a relief-like condition and to prepare a product with a three-dimensional effect by a method wherein a plurality of ink layers are heated and a foaming agent in capsules is evaporated to expand and deform particles and to emit an aromatic agent by making the aromatic agent-wrapped capsules explode during foaming thermally. CONSTITUTION: A picture design pattern of a rabbit drawn on the surface of a base body 2 consists of a base layer 5A prepd. by using e.g., a yellow foamable colored ink, a white contour proportion layer 5B of the rabbit, red local layers 5C of ears, eyes and a mouth and a black local layers 5D of a nose and a button. Foamable colored inks of each layer 5A-5D are prepd. by mixing volatile liq. foaming agent-wrapped particles 10 and liq. aromatic agent 11-wrapped particles 12 in capsules 9. The whole pattern is expanded into a relief-like condition and a three-dimensional effect is produced thereby without deforming the contour of the picture design pattern of a rabbit by a method wherein hot air is blown to heat each layer 5A-5D and the foaming agent 8 wrapped in the capsules 6 is evaporated to expand the particles 10. A position with a thin thickness of the capsule 9 is exploded and the wrapped aromatic agent 11 is emitted outside.

Detailed Description of the Invention (Field of Industrial Application) The present invention is applicable to various products on which various designs are printed, such as patches, stickers, picture books, coasters 1, and even wall hangings. The pattern is not flat, but can be finished to create a product with a three-dimensional effect and a high-class feel.In detail, a volatile liquid foaming agent is applied to a thermo-flexible resin shell. The present invention relates to a relief-like product in which a foamed colored ink prepared by mixing a large number of encapsulated particles with an aqueous dispersion or solution of a film-forming substance is laminated on the surface of a substrate so as to form a desired pattern.

(Prior Art) Conventionally known relief objects of this type include the following.

It is made by laminating multiple colored foam colored inks on the surface of a substrate such as non-woven fabric or paper using silk printing methods.
By applying heat to the relief-like material by, for example, blowing hot air from the surface using a hair dryer, thermospastic resin shells (hereinafter referred to as capsules) mixed in the ink of each layer are heated. The foaming agent in the capsule is evaporated or volatilized to expand and deform the capsule, that is, to expand and deform the particles, thereby enlarging the entire design pattern drawn in multiple layers in a relief shape and creating a three-dimensional effect. It was designed to be finished into a certain product.

(Problems to be Solved by the Invention) According to the conventional relief-like products described above, by making the design of the product three-dimensional, it is possible to improve the sense of taste and the added value of the product. Efforts are needed to further add value.

In particular, when heating and foaming patterns, unique odor components are emitted as the volatile foaming agent evaporates and volatilizes. There have been problems in applying it to products and items (products) used indoors.

This invention was made in view of the above circumstances, and not only suppresses the release of odor components during foaming by heating, but also
The purpose is to provide a relief-like material that can further improve the added value of the product and expand the range of applications through its aromatic effect when used over time.

(Means for Solving the Problems) In order to achieve the above object, the relief-like article according to the present invention consists of thermoplastic resin shells that contain a volatile liquid blowing agent and constitute particles. A fragrance is encapsulated in at least one part of the shell or another rupturable shell made of thermoplastic resin, and this is mixed with an aqueous dispersion or solution of a film-forming substance. do.

(Function) According to the present invention, by heating a plurality of laminated ink layers, the foaming agent in the capsule is evaporated or volatilized, and the particles are expanded and deformed, thereby enlarging the entire design pattern in a relief shape. It is possible to create a product with a three-dimensional effect. At the same time, during the heating and foaming described above, the capsule containing the fragrance is ruptured by heat to release the fragrance.

(Example) Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.
