종래의 인광을 발하는 칼슘, 아연계 황화물들은 발광시간이 짧고 습기가 많은 곳에서는 내광성이 약하여 실외부의 표지용으로는 부적당하였다. 이의 개선을 위해 Pm과 같은 방사성 물질을 혼합하면 발광지속시간을 늘일 수 있으나 방사성 물 질의 취급 규제로 사용에 상당한 제약이 따랐다.Conventional phosphorescent calcium and zinc sulfides have a short light emission time and are poor in light resistance at high humidity, and thus are not suitable for labeling of outdoor parts. To improve this, the mixing of radioactive materials, such as Pm, can increase the duration of light emission, but there are significant restrictions on their use due to the regulation of the handling of radioactive materials.

The color is purple, and the light emits purple at the initial emission. It is possible to provide a photoluminescent pigment composition having a long afterglow time, characterized in that. Here, if the mixing ratio of Sr 4 Al 4 O 25 is smaller or the mixing ratio of CaAl 2 O 4 is larger, the color tone and emission color become closer to red and the maximum afterglow time is reduced, and the mixing ratio of Sr 4 Al 4 O 25 is reduced. If there is more or less CaAl 2 O 4 mixing ratio decreases the afterglow time is closer to the tint and the emission color is blue.
