Abstract

PURPOSE:To produce foamed decorative material having unique soft touch handling with feeling of depth by a method wherein capsule foaming agent- containing translucent foamed resin layer is provided on base material colored in arbitrary color. CONSTITUTION:Colored solidly printed layer 2, on which translucent foamed resin layer 3 having uneven surface is produced, is provided on backing paper 1. The translucent foamed resin layer 3 having uneven surface can be produced by foaming capsule foaming agent, which is added in resin layer applied onto the colored solidly printed layer 2, under heat. The feeling of translucency can be controlled by the amount of the capsule foaming agent added to the resin and the spread of the resin. As a result, unique handling, which has soft touch superior to the touch developed by polyvinyl chloride and feeling of depth not hitherto experienced, can be obtained. Further, by applying pattern printing on the surface, pattern representation with further depth can be possible. Furthermore, by embossing the surface, unique feeling of embossing with depth can be expressed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a foamed decorative material, and particularly to a foamed decorative material suitable for use in interior materials such as wallpaper materials and ceiling materials.

[Prior Art] Conventional decorative materials having an uneven pattern include, for example, a backing paper coated with foamed or non-foamed vinyl chloride paste, printed on, coated with glossy or matte clear vinyl chloride paste, Foamed or embossed products are known.

[Problems to be Solved by the Invention] However, according to the above-mentioned prior art, the surface inevitably has the hard texture of vinyl chloride, and it is difficult to create a soft texture. Furthermore, since the depth of the pattern is expressed only by the combination of printed patterns, it also has the disadvantage of lacking a sense of depth.

The present invention was made in view of the above-mentioned conventional problems, and its purpose is to provide a foamed decorative material that has a unique texture with a soft touch and a deep feeling.

[Means for Solving the Problems] In order to achieve the above object, the foamed cosmetic material of the present invention is provided with a translucent foamed resin layer containing a capsule foaming agent on a base material colored in an arbitrary color. It is characterized by

Further, the present invention is characterized in that the surface of the translucent foamed resin layer is embossed.

Further, in the present invention, a pattern printing layer can be provided on the surface of the translucent foamed resin layer.

In the present invention, the combination of the colored solid printing layer and the translucent foamed resin layer having an uneven surface allows the colored solid color to be expressed in shading, as well as the unique soft touch of a PVC-free feel. You can get a nice texture.

Furthermore, when a pattern is printed on the surface of the translucent foam resin layer, the depth of the pattern can be expressed because the base is translucent, and the depth of the pattern changes depending on the shade of the color, so it is especially possible to express the depth of the pattern. In the case of certain printed patterns, it is possible to express patterns with great depth.

Furthermore, when the surface of the translucent foamed resin layer is embossed, the shading on the surface of the colored solid printing layer becomes noticeable, making it possible to express a deep and unique embossed feel.

The present invention will be explained in detail below.

In one aspect of the present invention, as shown in FIG. 1, a colored solid printing layer 2 is provided on a backing paper 1, and a translucent foamed resin layer 3 having an uneven surface is formed thereon.

As the backing paper 1, any material commonly used as a base material for decorative materials can be used.

The colored solid printing layer 2 can be easily provided on the backing paper 1 using a known printing means. Alternatively, it can be carried out by ordinary coating means.

Further, the translucent foamed resin layer 3 having an uneven surface is formed by coating a resin layer containing a capsule foaming agent on the colored solid print layer 2 and heating it to foam the capsule foaming agent. be able to.

The capsule blowing agent used is a hollow particle of thermoplastic resin in which a volatile substance (for example, a volatile hydrocarbon such as isobutane) is encapsulated. Vinylidene chloride-acrylonitrile copolymer or the like is used as the resin forming the capsule.

The particle size of the capsules preferably ranges from 5μ to 20μ. Such a capsule foaming agent foams when the volatile substance encapsulated therein evaporates when heated. Among the ones that have already been reprinted are Nippon Ferrite■
Examples include "Expancel (trade name)" manufactured by Matsumoto Yushi Seiyaku ■, and "Micropearl F-40 (trade name)" manufactured by Matsumoto Yushi Seiyaku ■.

As the resin constituting the translucent foamed resin layer 3, vinyl chloride resin or the like is suitable.

The translucency can be controlled by the amount of capsule foaming agent added to the resin and the amount of resin applied, but in the present invention, the capsule foaming agent is, for example, 3 to 3 parts by weight per 100 parts by weight of vinyl chloride resin. It is preferable to use 7 parts by weight, and the amount of resin applied is 150 to 350 g/r.
It is preferable that it is d.

In addition to the capsule foaming agent, the resin contains additives such as a solvent, a stabilizer, and a flame retardant.

To form the resin layer containing the capsule foaming agent on the colored solid print layer 2, any method such as gravure coating, roll coating, reverse coating, knife coating, screen printing, etc. may be used. Any method can be used to heat and foam the capsule foaming agent, such as placing it in a heating furnace or the like.

The thickness of the translucent foamed resin layer 3 after foaming is preferably about 0.20 to 1.0 m/m in order to achieve the desired texture.

Moreover, FIG. 2 shows an embodiment in which a pattern printing 4 is applied to the surface of the translucent foamed resin layer 3, and the depth of the pattern changes depending on the shade of the color. The lighter the color, the stronger the depth, which is especially noticeable when using transparent ink.

Note that the pattern printing 4 may be applied before the resin layer 3 is foamed, or may be applied after the resin layer 3 is foamed.

Further, FIG. 3 shows an embodiment in which the surface of the translucent foamed resin layer 3 is embossed, and since the colored solid color density of the base appears stronger in the four parts 3a than in the convex parts 3b, the surface of the colored solid printing layer 2 The shading of the embossed paper appears clearly, creating a deep and unique embossed feel.

[Example] The present invention will be described in more detail with reference to Examples below.

A 75 g/i flame retardant paper was used as the backing paper, and solid gray printing was performed on this paper. Furthermore, on top of this, a coating solution for a foamed resin layer having the composition shown below is applied using a knife coating method.
The resin was applied at a rate of 1240 g/rrr.

(Coating liquid composition) Vinyl chloride resin (vinyl acetate copolymer) 100 parts by weight Dioctyl phthalate 40 parts by weight Stabilizer (Ba-Zn system) 2 parts by weight Capsule blowing agent "Expancel (trade name)" (manufactured by Nippon Ferrite) ) 4 parts by weight flame retardant (phosphorus type) 10 parts by weight When this was passed through a heating furnace at 180° C. for 45 seconds, a foamed decorative material according to the present invention was obtained. The thickness of the translucent foamed resin layer after foaming was 0.50 m/m.

The obtained foamed decorative material had a distinct texture with a deep and soft touch, and the shading of the colored solid color was noticeable.

[Effects of the Invention] As explained in detail above, the foamed decorative material of the present invention has the advantage of being soft to the touch as if it were made from vinyl chloride, and having a unique texture with a depth not seen in the past. It has a great effect. Furthermore, by printing a pattern on the surface, it is possible to express a deeper pattern, and by embossing the surface, it is possible to express a deep and unique embossed feeling.
