Sealant compositions and methods for their use where the sealant compositions include a curable sealant and a photochromic material that undergoes a feature change upon exposure to radiation.

A method for analyzing an antioxidant content contained in a semiconductive material for a cable, which includes an amine-based antioxidant. The method can provide an accurate quantitative analysis value obtained by a comparison with the actual amount used, through gas chromatography (GC)/a flame ionization detector (FID).

A method of storing fluorescent dye-containing resin particles comprising adding the fluorescent dye-containing resin particles in a liquid comprising a buffer, a protein, and a surfactant, thereby obtaining a particle-containing liquid. The rate of change in the backscatter intensity (transmitted light) at the center of the height of the particle-containing liquid left to stand for 24 hours after the adding is not less than −1% based on the particle-containing liquid immediately after the adding.
