Problems solved by technology

Therefore, bright pigments having a gold tone have to become expensive, and their use tends to be limited due to cost
[0014] In addition, for bright pigments with an oxide coating, even if a pure gold-like hue is to be obtained, there is a problem that the desired hue cannot be obtained due to the viewing angle.

Embodiment 1

[0101] The bright pigment of embodiment 1 is as figure 1 As shown in the example of , the scaly glass substrate has a structure in which a base coating (silver coating), a gold coating, and a yellow coating are sequentially coated. The base material constituting the yellow coating is made of silica. The bright pigment of Example 1 was prepared as follows.

[0102] (Scaly glass substrate coated with silver coating)

[0103] First, MC2080PS manufactured by Nippon Sheet Glass Co., Ltd. was prepared as a scaly glass substrate coated with a silver coating. The flaky glass substrate has a structure coated with a silver film (thickness: 20 to 100 nm) by an electroless plating method.

[0104] (Formation of gold film)

[0105] The gold coating was formed by the electroless plating method as shown below. First, 6 g of sodium L-ascorbate as a reducing agent and 3 g of disodium hydrogenphosphate as a pH adjuster were added to 300 mL of pure water, and these were heated to 60° C. whi...

Embodiment 2

[0114] The bright pigment of embodiment 2 is as figure 2 As shown in the example of , the scaly glass substrate has a structure in which a base coating (silver coating), a yellow coating, and a gold coating are sequentially coated. MC2080PS was used in the same manner as in Example 1 for the scaly glass substrate covered with the silver coating. The method of forming the silica coating and the gold coating in which the yellow pigment is dispersed is the same as that in Example 1.

Embodiment 3

[0116] The bright pigment of embodiment 3 is as figure 1 As shown in the example of , the scaly glass substrate has a structure in which a base coating (silver coating), a gold coating, and a yellow coating are sequentially coated. The bright pigment of Example 3 was the same as the bright pigment of Example 1 except that a water-soluble yellow dye was used as the yellow pigment contained in the yellow coating, and aluminum hydroxide was used as the base material constituting the yellow coating.

[0117]First, as in Example 1, MC2080PS manufactured by Nippon Sheet Glass Co., Ltd. was used as a scaly glass substrate coated with a silver film, and gold particles with an average thickness of 1.4 nm were formed on the silver film by an electroless plating reaction. lamination. Next, after repeating filtration and water washing several times, the scaly glass substrate coated with the silver coating and the gold coating was heat-treated at 180° C. for 2 hours to be dried. The scal...

Abstract

A bright pigment with a gold tone of the present invention includes a scaly glass substrate 10, a base coating 20 containing at least one metallic material selected from the group consisting of silver, nickel and a nickel-based alloy, a gold coating 30 containing gold and a yellow coating 40 containing a yellow colorant and a parent material. The base coating 20, the gold coating 30 and the yellow coating 40 each form a layer covering the scaly glass substrate 10, and the base coating 20 is arranged innermost among the base coating 20, the gold coating 30 and the yellow coating 40.

Description

technical field [0001] The present invention relates to a bright pigment having a golden tone, and further relates to cosmetics, paints, inks, resin compositions and the like containing the pigment. Background technique [0002] Conventionally, as bright pigments, scaly aluminum particles, graphite flake particles, scaly glass particles, scaly glass particles coated with silver, and mica flake particles coated with metal oxides such as titanium dioxide and iron oxide are known. Wait. [0003] The surface of these bright pigments has the property of reflecting light and shining brightly, so they are used as materials such as paints, inks, resin compositions, and cosmetics. On the painted surface obtained by applying paint, the printed surface using ink, or the surface of a resin molded article molded using a resin composition, these bright pigments are combined with the color tone of the texture of the surface to give it a rich variety. It also has a unique appearance with ...
