Abstract: An object of the present invention is to provide a method for producing a coated material by using a composition that can be spray-coated, and that does not run downward after coating (i.e., rheology controllable). The method for producing a coated material includes step (1) of applying an electron beam-curable composition containing an ethylenically unsaturated group-containing compound to a substrate to form a coating film that has a surface viscosity of 1 Pa·s to 300 Pa·s as measured based on an electric-field pickup method, step (2) of drying the coating film obtained in step (1) to form a dry coating film when the electron beam-curable composition contains a volatile component, and step (3) of irradiating the substrate that has the coating film obtained in step (1) or the dry coating film obtained in step (2) with electron beams in an inert gas atmosphere to form a cured coating film.

Abstract: A coating method for forming a laminated coating film including a lower layer formed on a base material and an upper layer formed on the lower layer including: preparing a thermosetting coating material as a lower layer-coating material and preparing a thermosetting coating material as an upper layer-coating material; forming an uncured laminated coating film by applying the lower layer-coating material and the upper layer-coating material on the base material using a wet-on-wet technique; and simultaneously curing the lower layer-coating material and the upper layer-coating material by baking the uncured laminated coating film. In the preparation step, the lower layer-coating material and the upper layer-coating material are selected so that an absolute value of a difference in shrinkage ratio between the lower layer and the upper layer coating materials is 2.0% or smaller at a late stage of the baking step.

Abstract: A coating method for forming a laminated coating film including: preparing a thermosetting coating material as a lower layer-coating material, an intermediate layer-coating material, and as an upper layer-coating material; forming an uncured laminated coating film by applying the lower layer-coating, the intermediate layer-coating, and the upper layer-coating materials on the base material using a wet-on-wet technique; and simultaneously curing the lower layer-coating, the intermediate layer-coating, and upper layer-coating materials by baking the uncured laminated coating film. In the preparation step, the lower layer-coating, the intermediate layer-coating, and the upper layer-coating materials are selected so a sum of an absolute value of a difference in shrinkage ratio between the lower layer-coating and the intermediate layer-coating materials and an absolute value of a difference in shrinkage ratio between the intermediate layer-coating and the upper layer-coating materials at the late stage of the baking is 3.0% or smaller.
