Example Embodiment

[0204] Manufacturing example 1

[0205] In a reaction vessel equipped with a thermometer, a thermostat, a stirring device, a reflux condenser and a dripping device, 70.7 parts of deionized water and "Aクアロソ KH-10" (trade name, manufactured by Daiichi Kogyo Pharmaceutical Co., Ltd., emulsifier, effective Composition 97%) 0.52 parts, stirred and mixed in a nitrogen stream, and heated to 80°C. Next, 1% of the total amount in the following monomer emulsion and 5 parts of 6% ammonium persulfate aqueous solution were introduced into the reaction vessel and kept at 80°C for 15 minutes. Then, the remaining monomer emulsion was added dropwise to the reaction vessel kept at the same temperature over 3 hours. After the dropwise addition was completed, it was matured for 1 hour, and then 40 parts of 5% 2-(dimethylamino)ethanol aqueous solution was slowly added. It was added to the reaction vessel while cooling to 30°C, filtered with 100 mesh nylon cloth, and discharged at the same time to ob...

[0208] In a reaction vessel equipped with a thermometer, a thermostat, a stirring device, a reflux condenser and a dripping device, add 130 parts of deionized water and 0.52 parts of "Aクアロソ KH-10", stir and mix in a nitrogen stream, and heat up to 80°C . Next, 1% of the total amount in the following monomer emulsion (1) and 5.3 parts of 6% ammonium persulfate aqueous solution were introduced into the reaction vessel and kept at 80°C for 15 minutes. Then, the remaining monomer emulsion (1) was added dropwise to the reaction vessel kept at the same temperature over 3 hours, and aged for 1 hour after the dropwise addition was completed. Then the following monomer emulsion (2) was added dropwise over 1 hour, and after aging for 1 hour, 40 parts of 5% dimethylethanolamine aqueous solution was slowly added to the reaction vessel while cooling to 30°C, and filtered with 100 mesh nylon cloth , And discharged at the same time to obtain an average particl...

Abstract

The invention provides a transparent paint composition of a multilayer coating film, which is not easy to be affected by the roughness of the surface of the bottom material, the flatness and the DOI performance are excellent, when the coated object is sequentially coated by a first water coloration paint, a second water coloration paint, and a transparent coating, and then is solidified together to form the multi-layer coating film, and the multi-layer coating forming method. The paint composition comprises the acrylic resin (A) containing the hydroxyl, the melamine resin (B), and the polyhydric alcohols (C) having the special number-average molar mass in a range from 300-1500. The paint composition can be used as the transparent paint, and the coated object is sequentially coated by the first water coloration paint, the second water coloration paint, and the transparent coating, which are heated and solidified together to form the multi-layer coating.

Description

technical field [0001] The present invention relates to a coating composition and a method for forming a multilayer coating film using the coating composition. Background technique [0002] Conventionally, as a method of forming a coating film on an automobile body, a method in which electrophoretic coating is applied to the object to be coated and heated and cured, followed by intermediate paint coating → heat curing → primer coating Three-coating and two-baking method of painting → preheating (preheating) → clear paint coating → heat curing; and two-coating and two-baking method of intermediate paint coating → heat curing → topcoat coating → heat curing A method of forming a multilayer coating film. [0003] Generally speaking, the above-mentioned three-coating and two-baking method is carried out when a base coat paint containing a bright pigment is used to form a so-called metallic color coating film. In the case of so-called plain color coating films such as white and...
