PROBLEM TO BE SOLVED: To provide an optically gelatinizable composition having very high water content, enabling a granular material to be homogeneously compounded when containing the granular material, and especially enabling a stimulation-responsive polymer gel to be homogeneously dispersed and compounded therein. SOLUTION: The optically gelatinizable composition contains one or more kinds of a water-/organic solvent-soluble volatile material and a water-/organic solvent-insoluble granular material, and a gelatinizing agent, and is gelatinized by light irradiation. The gelatinizing agent contains at least a crosslinked and branched polymer, and further contains a polymer into which an ethylenic double bond is introduced by subjecting a carboxy group of a polyacrylic acid or a copolymer containing acrylic acid to a condensation reaction with N-methylolacrylamide or an N-alkoxymethylacrylamide.
