摘要： PROBLEM TO BE SOLVED: To provide a method of forming coating films in which in a process of piling up coating films in a wet-on-wet manner, water paint is used as a part of used paint to contrive saving resources and pollution control, and the coating films are subjected to crosslinking cure three-dimensionlly at the same time at room temperature or by heating to lower temperature (about 120 deg.C or less), and they excel in water resistance, interlayer adhesiveness and coagulation and destruction resistance without lowering smoothness, image clarity, weather resistance and the like. SOLUTION: Watre base paint consisting essentially of hydroxide group containing resin, coloring pigment and/or metallic pigment and a catalyst is applied to a film thickness of 10-25μ based on a dry coating film. Next, on the coated surface, paint consisting essentially of hydroxide group containing resin and polyisocyanate compounds having two or more free isocyanate groups in a molecule is applied to a film thickness of 25-50μ based on a dry coating film, and both the coating films are subjected to crosslinking cure three- dimensionally by polyisocyanate compounds.

摘要： PURPOSE:To form double-layered coating films having excellent pitting resis tance, etc., by applying a cation electrodeposition coating material, a barrier coat and aq. intermediate coating material wet on wet under specific conditions and curing the coating materials by heating. CONSTITUTION:The barrier coat consisting essentially of a modified polyolefin resin having -30 to -60 deg.C, more preferably -40 deg. to -50 deg.C static glass transition temp. of the formed coating film is applied on the uncured coating film surface coated with the cation electrodeposition coating material and further, the aq. intermediate coating material is applied thereon. These three-layered coating films are simultaneously cured by heating, by that, by the double layer coating films are formed. The coating material which is 10wt.% or less, more preferably 7wt.% or less in the coating material loss at the time of the curing by heating of the electrodeposition coating film subjected to the removal of moisture is used for the cation electrodeposition coating material at this time. As a result, the coating process is shortened and the double layer coating films having the excellent pitting resistance, finishing characteristic, etc., are obtd.

摘要： PURPOSE:To provide the coating composition containing a self-cross-linking resin having OH groups and blocked isocyanate groups in the molecule as a main component, capable of being used as a one pack type, not producing gels, and good in the adhesion to plastics. CONSTITUTION:The coating composition contains as a main component a self- cross-linking resin which has OH groups and blocked isocyanate groups in the molecule and which is obtained by reacting (A) a part of free isocyanate groups of a vinylic polymer having two or more of free isocyanate groups in the molecule (preferably a polymer produced from m-isopropenyl-alpha,alpha'- dimethylbenzyl isocyanate as an essential component) with (B) a part of the OH groups of a polyolefin resin having two or more of the OH groups in the molecule and subsequently reacting the remaining free isocyanate groups with (C) a blocking agent, or reacting a part of the free isocyanate groups of the vinyl polymer A and subsequently reacting all of the remaining free isocyanate groups with a part of the OH groups of the component B.

摘要： PURPOSE:To obtain the subject paint suitable as a base coat paint for the coating of a plastic by two-coat process and giving a coating film having excellent smoothness, etc., by compounding a water-base acrylic resin with a specific urethane resin emulsion at a specific ratio. CONSTITUTION:The objective paint is produced by compounding (A) 99-88wt.% (in terms of solid component) of a self-emulsified urethane emulsion produced by polymerizing an aliphatic and/or alicyclic diisocyanate, a polyether diol and/or a polyester diol having a number-average molecular weight of 500-5,000, a polyhydroxyl compound having low molecular weight and a dimethylol alkane to obtain a urethane prepolymer having an NCO/OH equivalent ratio of 1.1-1.9, neutralizing the prepolymer with a tert-amine and subjecting the prepolymer to water-extension and emulsification after or during the neutralization and (B) 1-12wt.% (in terms of solid component) of a water-base acrylic resin. The paint is compounded with a color pigment and/or a metallic pigment to obtain a base coat paint. A clear coal paint is applied to a plastic material coated with the base coat paint.
