@収顔料に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to colored UV-absorbing pigments, and in particular to fine-particle colored UV-absorbing pigments suitable for producing transparent colored UV-absorbing films.
@ Regarding pigment collection materials.
従来、雲母鱗片上にTi(hおよびプルシアンブルーを
順次被覆した着色顔料が知られている。(例えば特開昭
49−128028)
該着色顔料は、例えば10〜40μmの粒径。Conventionally, a colored pigment in which Ti(h) and Prussian blue are sequentially coated on mica scales is known. (For example, JP-A-49-128028) The colored pigment has a particle size of, for example, 10 to 40 μm.
約3.5rd/gの雲母粒子(約68重量部)の表面に
Ti(h被膜(26,4重量部)およびプルシアンブル
ー被膜(5,6重量部)が設けられた形状をしている。It has a shape in which a Ti(h coating (26.4 parts by weight) and a Prussian blue coating (5.6 parts by weight) are provided on the surface of mica particles (about 68 parts by weight) of about 3.5 rd/g.

が散乱されてしまい着色透明フィルムを作製できないと
いう問題点があった。Although the above-mentioned conventional colored pigments made from inorganic materials have good color development and good durability, when they are dispersed in a transparent resin and used in the form of a film, light is scattered. There was a problem that a colored transparent film could not be produced.
本発明は、良好な発色を与え、紫外光を吸収し、耐久性
が良好で、透明樹脂中に分散させても樹脂の透明性を失
なうことのない着色UV吸収顔料を提供することを目的
とする。The present invention aims to provide a colored UV-absorbing pigment that provides good color development, absorbs ultraviolet light, has good durability, and does not lose the transparency of the resin even when dispersed in a transparent resin. purpose.
本発明は、上記従来の問題点を解決するためになされた
ものであって、0.1μm以下の半導体微粒子の表面に
5〜30nm厚のシアノ鉄錯体膜を設けた着色顔料であ
る。The present invention was made in order to solve the above conventional problems, and is a colored pigment in which a cyano iron complex film with a thickness of 5 to 30 nm is provided on the surface of semiconductor fine particles of 0.1 μm or less.
本発明においては、0.1μm以下の半導体微粒子を基
材として使用しているが、粒径が0.1μmより大きい
と例えば透明樹脂中に分散させた際に可視光の散乱によ
り透明性を失なうことになる。In the present invention, semiconductor fine particles with a diameter of 0.1 μm or less are used as a base material, but if the particle size is larger than 0.1 μm, transparency may be lost due to scattering of visible light when dispersed in a transparent resin. It will happen.
又該粒径は小さすぎると取扱いにくくなるので10〜1
100nとすることが好ましい。Also, if the particle size is too small, it will be difficult to handle, so the particle size should be 10 to 1.
It is preferable to set it to 100n.
該基材としては半導体微粒子を用いているが、半導体微

着性が良好で均一なシアノ鉄錯体膜を形成することがで
きる。Semiconductor fine particles are used as the base material, but unless semiconductor fine particles are used, ultraviolet absorption characteristics will not be exhibited. Furthermore, unlike mica particles, it is easy to prepare semiconductor particles with a particle size of 0.1 μm or less, and they can be dispersed in a plating solution containing a cyano iron complex and then irradiated with ultraviolet light, resulting in good and uniform adhesion. A cyano iron complex film can be formed.
該半導体としては、TiOx微粒子等の2.9eV以上
の禁止帯幅を有する半導体が、紫外線を良好に吸収する
ので好ましい。As the semiconductor, a semiconductor having a forbidden band width of 2.9 eV or more, such as TiOx fine particles, is preferable because it absorbs ultraviolet rays well.
該半導体微粒子上に被覆されるシアノ・鉄錯体膜は5〜
30nm厚であるが、Snmより薄いとシアノ鉄錯体に
基づく光の吸収作用が小さくなり着色顔料としての効果
が低下する。又30nmより厚くなると吸光特性は飽和
し、着色顔料の生産性が低下する。The cyano/iron complex film coated on the semiconductor fine particles has a thickness of 5 to 5.
Although the thickness is 30 nm, if it is thinner than S nm, the light absorption effect based on the cyano iron complex becomes small and the effect as a color pigment decreases. Moreover, when the thickness exceeds 30 nm, the light absorption characteristics become saturated and the productivity of colored pigments decreases.
半導体微粒子上に形成されるシアノ鉄錯体の種類は、必

明着色フィルムを作製することができる。The colored UV-absorbing pigment of the present invention can be dispersed in a transparent resin to produce a transparent colored film, but when the film is used, for example, as one side film or an intermediate film of a plate glass, the transparent resin may be polyvinyl butyral, Preferably, vinyl acetate, polyurethane, polyacrylate, etc. are used. A transparent colored film can be produced by adding and dispersing about 1 to 20-t% of the colored pigment of the present invention in the transparent resin.

光の散乱により、透明性を得ることができなかった。In conventional colored pigments in which the surface of mica particles is coated with a semiconductor film and a Prussian blue film, it is difficult to grind the mica particles to a particle size of 0.1 μm or less. Transparency could not be obtained due to scattering of visible light when dispersed.
本発明においては、微粒子として半導体材料を用いてい

It was created. Dissolved oxygen was removed by bubbling Ar through the solution for 15 minutes and then sealed with a double cap. Next, Prussian blue was precipitated on the titania fine particles by irradiating the titania particles with light for 1 hour using a 400 W high-pressure mercury lamp as a light source.

From the figure, the fine particles coated with Prussian blue absorb UV light in the same way as the titania fine particles, and the fine particle concentration is 11.9w.
