摘要： PROBLEM TO BE SOLVED: To provide a multilayered coating film forming method, by which the vertical part and the horizontal part of a base material-to-be-coated are processed to have the same highly finished appearance for both the vertical part and the horizontal part even if the usage of coating materials is reduced when forming a double clear coating film on the base material-to-be-coated, and to provide a coated article obtained by the method. SOLUTION: In this multilayered coating film forming method, a base coating film, a first clear coating film, and a second clear coating film are sequentially formed on a material-to-be-coated. The material-to-be-coated has a horizontal part and a vertical part. The dry film thickness of the first clear coating film formed on the horizontal part of the material-to-be-coated is adjusted to

摘要： PROBLEM TO BE SOLVED: To provide a method for repairing a coating film which fields a high quality finish exhibiting the same appearance of a coating film both at the ground place and the non-ground place and forming no grinding stain. SOLUTION: In the method of repairing a defective part of an intermediate coating film in a process for forming a multiple coating film with a top clear coating film on a luster base-coating film after forming an electrode position coating film and the intermediate coating film on a base material to be coated, the repair of the coating film is performed with a process comprising the steps of: (1) grinding the defective part of the intermediate coating film and the peripheral place, (2) forming a coating film for repairing with a coating material prepared by removing the whole pigment or a luster pigment from the luster base coating material on the ground place and the peripheral place without backing, (3) forming the luster base coating film and the top clear coating film on the coating film for repairing and the intermediate coating film on the non-repairing part, and (4) baking and hardening the coating film for repairing, the luster base coating film and the top coating clear coating film at the same time.

摘要： PROBLEM TO BE SOLVED: To provide a method for forming a coating film exhibiting chipping resistance equivalent to or more than that of a vinyl chloride resin base plastisol coating material without corrosive gas being generated. SOLUTION: In a method for forming a chipping resistant coating film wherein a surface preparation process, an electrodeposited coating film forming process, and a process for forming a coating film consisting of polyurea resin composition are applied to a base material, and after that, a process for forming an intermediate coating film and/or a finish coating film is applied or not applied, a polyurea resin composition used contains resin components consisting of polyamine components containing 50 wt.% or more of an aromatic polyamine having polyalkylene chains or polyoxyalkylene chains and 1-15 wt.% of polyoxyalkylenepolyamine having at least two aliphatic amino groups in one molecule, and a polyisocyanate compound, and furthermore contains a plasticizer or not.

摘要： PURPOSE:To obtain the subject composition giving a coating surface free from steps and capable of easily forming an arbitrary pattern by using a specific amount of Fe3O4 or Fe3O4-supporting substance as an essential component. CONSTITUTION:The objective paint composition contains (A) 1-80wt.%, preferably 5-40wt.% (based on the solid component of the paint) of Fe3O4 and/or an Fe3O4-supporting substance and, as necessary, (B) preferably 1-20wt.% of a metallic pigment and/or a mica pigment. A pattern can be developed by applying the paint composition to a substrate and moving and orienting the component A e.g. by attaching a plurality of collected magnets to the back surface of the substrate or placing the magnets close to the coated surface.

摘要： PURPOSE:To obtain a coating compsn. containing Fe3O4 and/or Fe3O4 carrier with which desired patterns can easily be formed without steps on the surface of the coating film, and to provide the method of forming the film. CONSTITUTION:A coating compsn. containing Fe3O4 and/or Fe3O4 carrier as the essential component is applied while plural magnet aggregate are adhered to the back surface of the body to be coated or disposed near the coating film. Thus, magnetic force is applied on the Fe3O4 and/or Fe3O4 carrier to move and orient the Fe3O4 and/or Fe3O4 carrier to form the pattern.
