manufacture example 1

[0120] Production Example 1: Production of Carboxyl and Carbonyl-containing Emulsion (a1) for the Production of Red and White Colored Paint Particle Components

[0121] 285 parts of deionized water and 1 part of "New Cole 707SF" (Note 1) were placed in a 2-liter capacity four-necked flask, and stored at 85°C after nitrogen replacement. 3% of the pre-emulsion obtained by emulsifying the components of the following composition and 41 parts of 123 parts of the initiator aqueous solution obtained by dissolving 3 parts of ammonium persulfate in 120 parts of deionized water were added thereto. After 20 minutes, the remaining pre-emulsion and ammonium persulfate aqueous solution were added dropwise to the flask over 4 hours.

Abstract

An aqueous multicolor coating composition composed of a colored coating-particle component containing a coloring agent and an aqueous resin having a carboxyl group and another cross-linked functional group, and a coating formation component containing an aqueous resin having a carboxyl group, a hydrolysable silyl group, and another cross-linked function group. The coating formation component includes a specific amount of polyvalent metal, thereby making it possible to obtain an aqueous multicolor coating composition in which the colored coating particles are not liable to be crushed during spray application as well as roller application, and that is multicolored with excellent clarity, has good adherence to cloth, and can form a multicolored coating having excellent long-term weather resistance.

Description

technical field [0001] The present invention relates to a water-based multi-color pattern coating composition which is excellent in durability such as weather resistance, and can form a multi-color pattern coating film which is colorful and excellent in vividness of image not only by spray coating but also by roller coating. Background technique [0002] Multi-color pattern paint is a paint containing colored paint particles of various colors stably dispersed in a dispersion medium, and colorful patterns of various colors can be obtained through one painting, and it is mainly used for painting of buildings and the like. [0003] In recent years, due to concerns about the environment and various appearance needs of customers, people are required to develop water-based colorful pattern paints. [0004] For example, Japanese Patent Application Laid-Open No. 2005-15645 discloses a water-in-water type multicolor pattern paint composition, which is to disperse colored gel particle...
