preparation example Construction

[0091] The preparation method of the hydroxyl group-containing polyester resin (A2) is not limited, and can be performed by any conventional method. For example, the acid component and the alcohol component are heated at about 150° C. to 250° C. for about 5 hours to 15 hours in a nitrogen stream to perform esterification or transesterification of the acid component and the alcohol component. Thereby, a hydroxyl-containing polyester resin can be prepared.

[0092] For the esterification or transesterification of an acid component and an alcohol component, these components may be added to the reaction vessel at one time, or one or both of the components may be added in several portions. In addition, a hydroxyl group-containing polyester resin may be synthesized first and then subjected to a half-esterification reaction with an acid anhydride to thereby obtain a carboxyl group- and hydroxyl group-containing polyester resin. In addition, a carboxyl group-containing polyester resi...

[0229] The present invention is described in more detail below with reference to Examples and Comparative Examples; however, the present invention is not limited to these Examples. In the following examples, "part" and "%" are based on mass.

[0230] Preparation of hydroxyl-containing acrylic resin (A1) solution

preparation example 1

[0232] 30 parts of Swasol 1000 (trade name, produced by Maruzen Petrochemical Co., Ltd.; petroleum-based aromatic hydrocarbon solvent) were placed in a tank equipped with a thermometer, thermostat, stirrer, reflux condenser, nitrogen inlet tube and dropping funnel In a reaction vessel, it was heated to 110° C. while nitrogen was blown in. Subsequently, a polymerizable monomer solution containing 10 parts of styrene, 50 parts of methyl methacrylate, 28 parts of n-butyl acrylate, 4 parts or less of phosphoric acid group-containing monomers and 1.5 parts of 2,2'-azobisiso A monomer mixture of butyronitrile (AIBN) was added dropwise to the reaction vessel maintained at the same temperature over 4 hours. After completion of the dropwise addition, the mixture was aged for 1 hour. Subsequently, a mixture of 15 parts of butyl acetate and 1.0 part of 2,2'-azobisisobutyronitrile was further added dropwise into the reaction vessel over 1 hour. After the dropwise addition was completed,...

Abstract

This photoluminescent coating material composition is characterized by containing, in terms of solid content ratio based on the total of the resin solid contents of components (A), (B) and (C), said total being taken as 100% by mass, 10-90% by mass of a hydroxyl group-containing resin (A), 5-50% by mass of a curing agent (B), 1-40% by mass of a nonaqueous dispersion resin (C), 1-20% by mass of a basic pigment (D) and 1-30% by mass of a photoluminescent pigment (E). This photoluminescent coating material composition is also characterized in that: the nonaqueous dispersion resin (C) has a structure that has a core portion and a shell portion; and the shell portion of the nonaqueous dispersion resin (C) contains 0.05-5.0% by mass of a sulfonic acid group-containing polymerizable unsaturated monomer based on the total amount of polymerizable unsaturated monomer components that constitute the nonaqueous dispersion resin (C).

Description

field of invention [0001] Cross References to Related Applications [0002] This application claims priority from Japanese Patent Application No. 2014-81250 filed on April 10, 2014, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to bright coating compositions capable of producing multilayer coating films having high flop, minimal metallic mottle and excellent gloss. Background technique [0004] Recently, painting of automobile bodies and the like has required excellent finished appearance such as sharpness of image and smoothness and luxurious design. Glitter coating compositions employing gloss pigments, such as metallic coating compositions and interference color coating compositions, have been frequently used. [0005] In consideration of, for example, the appearance of the formed coating film and production efficiency, the above-mentioned coating generally uses a method using atomization of...
