Printability of an Aqueous Gravure Ink for Polyolefin

Polyolefin용 수성 Gravure Ink의 인쇄작성

The photosensitive properties and carrier transport in the organic photoconductor with the carrier transport layers(CTL) of polymer matrix doped with two carrier transport materials above carrier generation layer(CGL) containing oxotitanium phthalocyanine (TiOPc) were investigated. The CGL of TiOPc dispersed in poly(vinylbutyral) was formed as thickness of 0.1${\mu}{\textrm}{m}$and the carrier transport layer was prepared by coating polycarbonate and polyester doped with oxadiazoly(OXD), polyvinylcarbazole (PVK), trinitro fluorenone(TNF) as thickness of 10~15${\mu}{\textrm}{m}$, respectively. We have measured half decay exposure,sensitivity and xerographic gain from the photo-induced discharge curve(PIDC). In this work, it was found that the characteristics of carrier transport were mainly caused by the ionization potential difference of constitutive materials in molecularly doped polymer.
