物に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an ultraviolet curable resin composition, particularly (ii) the composition suitable as a flame retardant coating agent for optical fibers.
（従来の技術）

向上や、膨張係数の調整を目的として無機粉体を分散さ
せることは広く行われている。他方 −紫外線硬化型
樹脂は硬化が短時間であることと作業性にすぐれている
ため、塗料等に広く使用されている。(Prior Art) Conventionally, it has been widely practiced to disperse inorganic powder into resin compositions for paints for the purpose of improving flame retardancy, abrasion resistance, weather resistance, and adjusting expansion coefficient. On the other hand - Ultraviolet curable resins are widely used in paints and the like because they cure in a short time and have excellent workability.
しかしながら、紫外線硬化性樹脂を用いた感光性樹脂塗
料も、５０μｍ以上のような厚塗りの場合、特に分散型
（サスペンション）塗料では分散体によって紫外線がさ
えぎられるために、硬化時間が長くなり硬化不能になる
欠点がある。However, even with photosensitive resin paints using ultraviolet curable resins, when coating thickly such as 50 μm or more, the curing time becomes longer and curing becomes impossible, especially in dispersion type (suspension) paints, as the ultraviolet rays are blocked by the dispersion. There are drawbacks to it.
この欠点の解決策として充填剤として球状のガラス粒子

こと自体きわめてコスト高となり、また球状のガラス粒
体もその製造調達は容易でない。As a solution to this drawback, the use of spherical glass particles as a filler is treated with a surface treatment that reflects ultraviolet rays, such as trowel plating, and allows ultraviolet rays to enter the interior from this reflection angle. Resin paints that are suspension paints but can be cured by ultraviolet light have been developed. This silver plating also has the effect of imparting conductivity to the coating film, but in any case, silver plating itself is extremely costly, and spherical glass particles are not easy to manufacture and procure.

硬化性樹脂組成物を製造することができる。The quartz glass powder used in the present invention is borosilicate soda glass, natural quartz glass, and synthetic quartz glass, and all of them can achieve the desired purpose without requiring reflective coating surface treatment such as the silver plating described above. UV curing is achieved. Moreover, in this case (2), it is possible to produce a suspension-type ultraviolet curable resin composition that can be used in practice by a simple production method. .

しい。The blending ratio of the quartz glass powder in the ultraviolet curable resin composition needs to be in the range of 5 to 80% by volume. If it is less than 5%, the effect of inorganic filler blending, such as improvement in flame retardancy, abrasion resistance, weather resistance, or adjustment of the expansion coefficient of the resin composition, will be insufficient;
If it exceeds this, the applicability of paints etc. will be poor, so it is desirable to keep it within the above range, particularly in the range of 20 to 40%.

At this time, if necessary, inorganic or organic extender pigments may be added for the purpose of coloring, but these should be kept within a range that does not impair the effects of the present invention.
