PROBLEM TO BE SOLVED: To provide an aqueous developable pre-sensitizing color calibrating component, particularly, a color calibrating structure body by introducing an alkyl vinyl or aryl vinyl maleic acid anhydride part-ester copolymer having pendant ethylene type unsaturated groups to a photosensitive color layer to reproduce an improve half tone dot. SOLUTION: A negative color calibrating component contains (a) a separative carrier, (b) (i) a photopolymerizing oligomer containing an alkyl vinyl or aryl vinyl maleic acid anhydride part-easter copolymer which has plural pendant ethylene type unsaturated groups and has the acid number of 100 to 250 and has number average molecular weight of 1,000 to 20,000, (ii) a coloring agent and (iii) a photosensitive color coating film containing a light initiator, (c) a photopolymerizing barrier coating film and (d) a thermally activating adhesive in order.
