PROBLEM TO BE SOLVED: To enable a high-molecular weight hindered amine-based optical stabilizer to be well dissolved in a curing composition containing a modified silicone polymer. SOLUTION: A mixture containing a drying oil having an iodine value of 130 to 200 and a hindered amine-based optical stabilizer having a molecular weight of 1,000 to 5,000 is heated at a temperature of the melting point or higher of the hindered amine-based optical stabilizer in the mixture to dissolve the hindered amine-based optical stabilizer to thereby obtain an optical stabilizer composition, which then is mixed with a polymer-containing liquid containing a polyoxyalkylene polymer (P) having a hydrolyzable silicon group.
