PROBLEM TO BE SOLVED: To obtain the subject retarding agent having sufficient coating film properties and capable of expressing a low viscosity capable of forming films by bringing the agent to contain a vinyl group-containing dendrimer which contains a vinyl group containing a secondary or tertiary amine structure. SOLUTION: This retarding agent for reactive oxygen inhibition comprises a dendrimer consisting of a core part, a branched part, a branch part and at least 4 terminal parts and containing at least one species out of a secondary or tertiary amine structure and long chain groups expressed by formula I-III [R1 is a phenyl or H: (n) is 4-25; (x) is 1-6; R3 is a phenyl or the like; (y) is 2-22; (z) is 2-15 (m) is 1-25; and (k) is 1-20], or at least one active hydrogen- containing group such as a primary or secondary amino group expressed by formula IV (R1 is H or a <=3C alkyl), a hydroxysilyl group of formula V [R4 is a phenyl or the like; and (n) is 1-3], a phosphate group or the like and a vinyl group. The retarding agent can provide cured products by heat or active energy rays even in >=500 ppm oxygen concentration.
