  • the scaly pigment prepared in Example 5, the alkyd resin varnish, the melamine resin varnish, and the soot sol are mixed in the blending amounts shown in Table 8, and are used for 60 minutes using a disperser (paint shaker). Dispersion formed a dispersion vehicle. Next, an alkyd resin varnish and a melamine resin varnish were further added to the obtained dispersion vehicle and stirred to obtain a coating composition.

Abstract

L’invention concerne un pigment contenant des microparticules d’or qui excelle non seulement en stabilité et en homogénéité du développement de couleur mais qui, lors du développement de couleur rougeâtre, réalise un ton de couleur plus profond que dans la technique antérieure. Le pigment contenant des microparticules d’or a une structure telle que les microparticules d’or en tant que source de développement de couleur sont dispersées dans une matrice vitreuse contenant de l’oxyde de silicium sous forme de composant construisant un réseau, ladite matrice contenant de préférence de l’oxyde de titane et de l’oxyde de fer.
