There can be obtained a suitable optical material which has a stable structure with a rare earth metal ion while maintaining transparency in a region of from visible light to near infrared light. The optical material is obtained by curing a fluorine-containing resin composition comprising (I) a fluorine-containing prepolymer and (II) a compound containing a rare earth metal ion and/or a rare earth metal element, wherein the fluorine-containing prepolymer (I) is a curable fluorine-containing poly...

A composition which is obtained by causing a specific compound to be present together with sucralose. The composition provides a sucralose in a stable form, more particularly, a sucralose which is still stable and thus is significantly suppressed with respect to the decrease in sweetness and discoloration (browning blackening), even when it is subjected to a warming treatment under a condition wherein temperature is high and especially water content is low and/or pH is low. The stabilized sucral...
