各種交通標示物の塗料等に用いるのに好適な夜間視認性
に優れる交通標示用顔料組成物に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a heat melting type road marking paint, a water-based or oil-based paint type so-called paint type road marking paint, and a pasting type road marking material. The present invention relates to a pigment composition for traffic marking, which is suitable for use as a paint for road marking materials and other various traffic markings and has excellent night visibility.
路面標示用塗料は、舗装道路面の中央線、車線区分、
停止線、横断歩道、飛行場の滑走路などのための塗装材
である。また、各種道路標識は、交通ルールの遵守、交
通安全上不可欠のものであり、これらの材料が、その目
的にあった機能を発揮するためには、鮮明な目立った色
彩の塗料が望まれる。Road marking paints are used for the center line of the paved road surface, lane division,
It is a coating material for stop lines, pedestrian crossings, and airfield runways. In addition, various road signs are indispensable for observing traffic rules and traffic safety, and in order for these materials to exhibit the functions suited to their purposes, a paint with a clear and distinct color is desired.
道路交通管理上重要な認識色相である黄色の顔料は、
現在、黄鉛顔料が用いられている。Yellow pigment, which is an important hue for road traffic management,
Currently, yellow lead pigments are used.
しかしながら、黄鉛は、クロムと鉛を含有する無機顔
料なので、公害規制上の問題を常に抱えており、無公害
型の有機顔料への代替が望まれてから久しい。However, since yellow lead is an inorganic pigment containing chromium and lead, it always has problems in terms of pollution control, and it has been a long time since a substitute for a non-polluting organic pigment was desired.
有機顔料は、無機顔料より鮮明で、着色力があり、品
種が多く、各種色相に対応でき、耐熱、耐候性に優れた
物が多い。しかし、これまで、有機顔料への置き換えは
あまり進んでいない。Organic pigments are sharper than inorganic pigments, have coloring power, are of various types, are compatible with various hues, and are excellent in heat resistance and weather resistance. However, replacement with organic pigments has not progressed so far.
有機顔料の代替が、進行しないもののひとつに、舗装
道路のセンターライン等に使用されている黄色の路面標
示塗料がある。黄色のセンターラインは、とくに、夜間
における視認性が交通安全上重要視される。One of the things that the substitution of organic pigments has not progressed is the yellow road marking paint used for the center line of paved roads. For the yellow center line, visibility at night is particularly important for traffic safety.
道路標示用塗料の夜間視認性とは、センターラインな

どのヘッドライトでは、再帰反射光量がきわめて少なく

ることがおこるという欠点がある。The night visibility of the road marking paint means that the color of the center line and the like can be sufficiently identified by the lights of street lights and vehicle headlights at night. Road marking paints colored with organic pigments lack night visibility, and the amount of light is low even when yellow paints with sufficient sharpness and color density that can be identified in daylight are applied on the road. At night, a headlight of a vehicle or the like has a drawback that the amount of retro-reflected light becomes extremely small, and a driver of a vehicle may not recognize yellow.
本発明者等は、この様な状況に鑑みて鋭意研究した結

物が、夜間視認性に優れ、交通標示用の顔料として好適
であることを見い出し、本発明を完成するに至った。The present inventors have conducted intensive studies in view of such circumstances, and as a result, a pigment composition in which an organic pigment is attached to the surface of an inorganic pigment has excellent night visibility and is suitable as a pigment for traffic marking. After finding out that, the present invention has been completed.
すなわち、本発明は、無機顔料粒子の表面に有機顔料

挙げられ、なかでも二酸化チタンが好ましい。The inorganic pigment used in the present invention is not particularly limited as long as it has a hue corresponding to the desired hue and is not particularly limited, but among them, an inorganic pigment having a refractive index of 1.7 or more, preferably 2.0 or more is preferable. For example, when the desired hue is yellow, rutin-type titanium dioxide, anatase-type titanium dioxide, and those coated with aluminum oxide or silica, yellow iron oxide, chromatic inorganic pigments such as yellow mica titanium. Among them, titanium dioxide is preferable.

る事が大切である。The hue of the organic pigment attached to the surface of the core inorganic pigment is essentially any hue required for traffic marking, and is not particularly limited. Therefore, the type of organic pigment is not particularly limited. By way of example, monoazo pigments, disazo pigments, phthalone pigments, metal complex pigments, quinacridone pigments, peridene pigments, phthalocyanine pigments and the like can be mentioned. However, if it is used for traffic signs, weather resistance is required, and if it is a road marking paint, heat-melting type is heat resistant, paint type is solvent resistant,
In addition, it becomes necessary and it is important to select a pigment that satisfies these conditions.
