摘要： PROBLEM TO BE SOLVED: To improve interlaminar adhesion between a first clear paint film and a second clear paint film by a method wherein a colored base coating material and a first clear coating material are applied to a shell part of a car body, preheated at a specific temperature, and thereafter a second clear coating material is applied, and heated to cure three layers of paint films simultaneously. SOLUTION: A colored base coating material and a first clear coating material are applied to a shell part of a car body, and both paint films are preheated at 70-100 deg.C. After applying a second clear coating material thereto, these three paint films are simultaneously cured by heating. Herein, both paint films composed of the colored base coating material and the first clear coating material are not crosslinked and cured by this preheating, gel fraction is about utmost 5wt.%, and further a solid content of the first clear coating material is preferably about 80wt.% or higher. Thereby, thick film (for example, about 30μm or over in cured paint film) application of the second clear coating material can be executed, and further interlayer adhesion between the first clear paint film and the second clear paint film is improved.

摘要： PURPOSE:To obtain a room temperature-drying nonaqueous resin dispersion having excellent stability and coating properties, by polymerizing a vinylically unsaturated monomer in a dispersion in an organic solvent in the presence of a specified vinyl graft alkyd resin as a dispersion stabilizer. CONSTITUTION:A vinyl graft alkyd resin (I) comprising 10-70wt.% alkyd resin (A) modified with a (semi)drying oil of an oil length of 30-80% and/or a (semi-) drying oil fatty acid and 90-30wt.% vinyl polymer (B) is used as a dispersion stabilizer. It is necessary that the monomer (a) which is the structural component of the vinyl polymer (B) should contain at least 30wt.% vinyl unsaturated monomer (b) of an SP value =20 deg.C. This resin dispersion is obtained by polymerizing a vinylically unsaturated monomer (c) in the presence of resin (I) in a dispersion in an organic solvent in which resin (I) is soluble or partially soluble and in which the monomer is soluble but the formed polymer is insoluble and contains polymer gel particles insoluble in said organic solvent.
