PROBLEM TO BE SOLVED: To provide a material for detecting the track of a particle beam capable of highly sensitively detecting charged particles having large energy, securing both satisfactory surface conditions after etching and a sufficiently large ratio of etch pits to background, and having little degradation, so-called aging, in sensitivity due to storage for a long period of time prior to use and very few reductions and contraction, so-called fading, in the number and diameter of etch pits with the passage of time from the incidence of radiation to etching. SOLUTION: In the material for detecting the track of a particle beam, allyl diglycol carbonate is used, and a polyphenol-based oxidation inhibitor, pentaerythrityl-tetrakis[3-(3.5-ditertiarybutyl-4-hydroxyphenyl) propionate] is added to its monomer.
