▎ 摘  要

NOVELTY - Intermediate transfer member (2) comprises: a layer (a) comprising a phenoxy resin with graphene particles (0.1-3 wt.%, based on the weight of the layer) dispersed in the phenoxy resin; a surface layer comprising a phenoxy resin (I) with graphene particles (0.1-3 wt.%, based on the weight of the layer) dispersed in the phenoxy resin; and a layer (b) comprising a phenoxy resin (II) with graphene particles (0.1-3 wt.%, based on the weight of the layer) dispersed in the phenoxy resin. The surface layer exhibits a light transmittance of 70% for light having a wavelength of 700 nm. USE - The intermediate transfer member is useful in an apparatus for producing images. ADVANTAGE - The intermediate transfer member exhibits required electrical conductivity even at reduced use of electrically conductive fillers, is robust, and exhibits long life. DETAILED DESCRIPTION - Intermediate transfer member (2) comprises: a layer (a) comprising a phenoxy resin with graphene particles (0.1-3 wt.%, based on the weight of the layer) dispersed in the phenoxy resin; a surface layer comprising a phenoxy resin of formula (I) with graphene particles (0.1-3 wt.%, based on the weight of the layer) dispersed in the phenoxy resin; and a layer (b) comprising a phenoxy resin of formula (II) with graphene particles (0.1-3 wt.%, based on the weight of the layer) dispersed in the phenoxy resin. The surface layer exhibits a light transmittance of 70% for light having a wavelength of 700 nm. m = 1-399; p = 399-1; and n = 40-400. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the apparatus for producing images.
