Provided is an &#x3b1;-aminoalkylphenone compound that has good stability and low sublimability, efficiently generates radicals when irradiated with a bright line at 365 nm (I line) or the like, and is useful as a polymerization initiator to be used in a radically polymerizable composition. The &#x3b1;-aminoalkylphenone compound is represented by Formula (I) mentioned below. In Formula (I) mentioned above, it is preferable that Ris a nitro group, an alkoxy group having 1 to 12 carbon atoms, or an alkoxycarbonyl group having 1 to 12 carbon atoms. The &#x3b1;-aminoalkylphenone compound can be preferably used in a polymerization initiator.

A color conversion filter contains at least one kind of squarylium dye that radiates fluorescence light, has a wavelength conversion capability, absorbs light in an unneeded wavelength region, radiates fluorescence light in a preferable wavelength region, and does not allow decrease in brightness, and thus is preferable for color conversion light-emitting devices, photoelectric conversion devices and the like. Specifically, the color conversion filter has an absorption having a high intensity in the range of 570 to 600 nm, and thus is preferable for use in a color conversion filter that radiates fluorescence light having a high intensity in the range of 600 to 780 nm.
