The invention discloses a photopolymerizable composition comprising at least one, ethylenic unsaturated bond-containing compound, a hexaaryl-biimidazole compound, and an organoboron compound represented by a specific general formula; and discloses a photosensitive thermal recording material having a recording layer that contains the photopolymerizable composition. The photopolymerizable composition and the photosensitive thermal recording material of the invention are highly sensitive to UV rays and visible to IR rays falling within a wavelength range that includes wavelengths not longer than 450 nm, and are effective for decoloring a dye component that absorbs the rays falling within the wavelength range.
