様の塗膜を形成している。An example of the above-mentioned conventional uneven pattern coating method is disclosed in Japanese Patent Application Laid-Open No. 60-102979. To give an overview, after applying a primer paint to the exterior wall, etc., inorganic aggregate such as kansui stone is sprinkled on the painted surface, and a binding material is applied on top of this in a scattered manner, and this binding material is applied to the bone. A flat convex portion is formed by pushing the material to the upper end position, and finally, a top coat is applied to the flat convex portion and other parts to form a coating film with an uneven pattern.
（発明が解決しようとする問題点）
しかしながら、上記塗膜構造で深みのある凹凸模様を形
成するためには、大量の無機系骨材が必要となり、しか
も重量が増大するという欠点があった。(Problems to be Solved by the Invention) However, in order to form a deep uneven pattern with the above coating structure, a large amount of inorganic aggregate is required, and there is a drawback that the weight increases.

機系骨材との界面に亀裂等の損傷を生じ易いという問題
もあった。In addition, when forces such as expansion and contraction or vibration are applied to the paint film, elastic deformation is difficult due to the inorganic aggregate, causing damage such as cracks to the paint film, especially the interface between the paint film and the inorganic aggregate. There was also the problem that it was easy to cause.
