【Task】 Provided is a composition for forming a protective film against an aqueous solution of hydrogen peroxide. [Solution] A resin, a compound represented by the following formula (1a), formula (1b) or formula (1c), a cross-linking agent, a cross-linking catalyst, and a solvent, wherein the resin has the formula (1a), the formula (1b) or the formula A protective film-forming composition for an aqueous hydrogen peroxide solution, comprising the compound represented by (1c) in an amount of up to 80% by mass and the cross-linking agent in an amount of 5 to 40% by mass. Embedded image (Wherein, X represents a carbonyl group or a methylene group, l and m each independently represent an integer of 0 to 5 satisfying a relational expression of 3 ≦ l + m ≦ 10, n represents an integer of 2 to 5, u represents And v each independently represent an integer of 0 to 4 satisfying a relational expression of 3 ≦ u + v ≦ 8, and R 1 , R 2 , R 3 and R 4 each independently represent a hydrogen atom, a hydroxy group, or a hydroxy group as a substituent. Or a hydrocarbon group having 1 to 10 carbon atoms which may have at least one double bond in the main chain, or may have at least one hydroxy group as a substituent. When R 1 , R 2 , R 3 and R 4 represent an aryl group having 6 to 20 carbon atoms, and R 1 , R 2 , R 3 and R 4 represent a hydrocarbon group having 1 to 10 carbon atoms, R 1 and R 2 , R 3 and R 4 Together with the ring carbon atom to which they are attached form a benzene ring It may form, the benzene ring may have at least one hydroxy group as a substituent, j and k each independently represent 0 or 1.)
