COATING MATERIAL APPLYING METHOD

To provide a coating material applying method that can form a coated film having an even thickness without causing leakage on a slope coated surface as well.SOLUTION: A coating material applying method forms a coated film on a coated surface by discharging droplets of coating materials while moving an inkjet print head along application paths. The application paths include a plurality of first paths respectively extended in a second direction and arranged with an interval from each other in a first direction and at least one second path arranged between the two first paths made adjacent to each other in the first direction with an interval from the first paths, where a direction in which an inclination gradient on the coated surface is maximum is defined as the first direction and a direction perpendicular to the first direction is defined as the second direction. The method includes the following steps: (1) a first application step of forming a first layer of the coated film along the first path; (2) an intermediate drying step of drying the first layer of the coated film; and (3) a second application step of forming a second layer of the coated film in a mode in which the layer adheres tightly to the first layers of the adjacent two coated films, along the second path.SELECTED DRAWING: Figure 4 【課題】傾斜塗装面にも垂れを生じることなく均一な厚さの塗膜を形成し得る塗料の塗布方法を提供する。【解決手段】塗布方法は、インクジェットプリントヘッドを塗布パスに沿って移動させながら塗料液滴を吐出することにより塗装面上に塗膜を形成するものであり、塗装面上において、傾斜勾配が最大の方向を第１方向、これと垂直な方向を第２方向とするとき、塗布パスは、それぞれが第２方向に延び、第１方向に互いに間隔をあけて配列された複数の第１パスと、第１方向に隣接する２つの第１パスの間で、これらから間隔をあけて配列された少なくとも１つの第２パスとを含み、以下の工程を含む。（１）第１パスに沿って塗膜の第１層を形成する第１塗布工程（２）塗膜の第１層を乾燥させる中間乾燥工程（３）第２パスに沿って、隣接する２つの塗膜の第１層に密着するような態様で、塗膜の第２層を形成する第２塗布工程【選択図】図４
