2 results about "M-aminoacetophenone" patented technology

An electrophotographic photoreceptor includes: a conductive base, a photosensitive layer provided on the conductive base, and a protective layer provided on the photosensitive layer. The protective layer is a cured body of a photocurable composition that includes a photocurable compound and a photopolymerization initiator. The photopolymerization initiator includes a first compound having an acylphosphine oxide structure and a second compound having an α-aminoacetophenone structure and an absorption coefficient at a wavelength 365 nm smaller than that of the first compound. A total content of the first compound and the second compound with respect to 100 parts by mass of the photocurable compound is 5 parts by mass or more and 20 parts by mass or less.

A curable resin composition which has high light sensitivity and good touch dryness and can obtain good flexibility, welding heat resistance and cross-sectional shapes, a dry film, a cured product and an electronic component. The curable resin composition comprises: (A) a carboxyl-containing resin having a bisphenol F backbone, (B) a photopolymerization initiator, (C) a photosensitive monomer, (D) an epoxy resin, and (E) an inorganic filler, wherein the photopolymerization initiator (B) comprises: (B1) an aminoacetophenone-based photopolymerization initiator, and (B2) a benzophenone-based photopolymerization initiator; and the photosensitive monomer (C) comprises: (C1) a di(meth)acrylate having a polypropylene glycol backbone.
