Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a black pigment using carbon black particles and suppressing ultraviolet light absorbability of the carbon black particles, and to provide a black photopolymerizable composition compounded with the carbon black particles and suppressing ultraviolet light absorbability by the carbon black particles. SOLUTION: This black pigment consists of a composition comprising carbon black particles 10-500 nm in average size and inorganic compound particles 5-1,000 nm in average size; wherein the portion of the inorganic compound particles to the carbon black particles is 1-30 wt.% the other black photopolymerizable composition is obtained by including at least a photopolymerization initiator and a photopolymerizable monomer and compounding carbon black particles 10-500 nm in average size and inorganic compound particles 5-1,000 nm in average size; wherein the proportion of the inorganic compound particles to the carbon black particles is 1-30 wt.%.
