ヤが出る等の問題がある。2. Description of the Related Art In recent years, wall paper made by scattering particulate matter on a base sheet has been proposed as a wall material. Such a wallpaper is, for example, a foamable resin composition is applied in a pattern to a base sheet, and before the resin composition is dried, resin particles are sprayed thereon, and then heated and foamed. Can be obtained by melting and bonding the resin to a foamable resin composition (JP-A-1-97641 and JP-A-1-97642). However, in this type of conventional wallpaper, at the time of heating and foaming, each resin particle is mutually melted or melted with the foamable resin composition to be integrated with each other, and the granular feeling becomes poor or the surface becomes shiny. There's a problem.
この問題を解消するため、樹脂粒として、加熱発泡時
に溶融しない樹脂粒を用いることが提案されているが、
そのような樹脂粒は発泡性樹脂組成物と接着しにくく、

る問題がある。In order to solve this problem, it has been proposed to use resin particles that do not melt during heating and foaming as resin particles.
Such resin particles are difficult to adhere to the foamable resin composition,
There are drawbacks in that resin particles are likely to fall off and the cost is high. In addition, the use of inorganic particles has also been proposed, but this is also difficult to adhere to the foamable resin composition,
There is a problem that the obtained wallpaper is too hard to be suitable as a wall material.
このような事情に鑑み、本発明者らは、加熱発泡時に
溶融する樹脂粒を用いて、かつ、粒状感に優れた壁紙を
得るべく、鋭意検討し、本発明を完成するに至った。In view of such circumstances, the present inventors have conducted intensive studies using resin particles that melt during heating and foaming and to obtain wallpaper having excellent granularity, and have completed the present invention.

な、粒状感に優れた壁紙が得られる。Means for Solving the Problems The present invention applies a foamable or non-foamable resin composition onto a substrate sheet, and further, before the resin composition dries, the melting temperature of the resin composition ± After spraying a mixture of a resin particle having a melting temperature of 30 ° C. and an inorganic powder in a weight ratio of 1: 0.1 to 1.5, a method for producing a granular material spray wallpaper characterized by heating or melting or foaming is provided. is there. According to the production method of the present invention, the resin particles and the inorganic powder are mixed at a predetermined ratio and sprayed, so that even if the resin particles having a melting temperature equivalent to that of the foamable resin composition are used, the resin particles can be mixed with each other. Can be sufficiently prevented from being fused and integrated with the foamable resin composition, and a wallpaper having excellent adhesion between the resin particles and the foamable resin composition and having an excellent granularity can be obtained.
