Abstract: [Problems] To provide a novel compound which has a high carrier mobility and is useful as a charge-transporting agent that is not only capable of stably forming a photosensitive layer without precipitating crystals or forming pinholes at the time of forming the photosensitive layer but is also capable of forming an organic photosensitive material for electrophotography that has a high sensitivity and a low residual potential. [Means for Solution] A diphenylnaphthylamine derivative represented by the following general formula (1), wherein R1 to R3 are alkyl groups, k is an integer of 0 to 3, j is an integer of 0 to 4, l is an integer of 0 to 6, and X1 and X2 are hydrocarbon groups having at least one ethylenically unsaturated bond.

Abstract: A method of manufacturing a shadow mask assembly, in which a shadow mask is fastened to a support frame in a tensioned state, includes applying a preliminary tension force with a magnitude of 9.8 to 490 N to the four corners of the shadow mask outwardly aslant with respect to sides of the shadow mask. A main tension force is then applied to each of at least a pair of mutually opposite sides of the shadow mask outwardly perpendicularly to the sides. Thereafter, the shadow mask to which the main tension forces have been applied is fastened to the frame side of the support frame.

Abstract: A shadow mask can be attached to a support frame in an accurate planer state without unevenness. Provided is a method for manufacturing a shadow mask assembly in which a shadow mask is fastened to a support frame in a tensioned state, the method including applying a preliminary tension force of an strength of 9.8 to 490 N to the four corners of the shadow mask outwardly aslant with respect to sides of the shadow mask, applying a main tension force to each of at least a pair of mutually opposite sides of the shadow mask outwardly perpendicularly to the sides, and thereafter fastening the shadow mask to which the main tension forces has been applied when the main tension forces are applied to the frame side of the support frame.
