Abstract
A transfer sheet for electrostatically transferring thereon an electrically conductive or electrically semi-conductive toner in electrostatic photography or electrostatic printing, which comprises a substrate and a toner-receiving layer formed on at least one surface of the substrate, which toner-receiving layer contains a composition comprising (A) 100 parts by weight of thermoplastic acrylic-styrene copolymer and (B) 10 to 100 parts by weight of dry method finely divided silica is disclosed. In this transfer sheet, the electric resistance can be maintained at a high level even under high humidity conditions, and a toner image can be transferred on this transfer sheet at a high transfer efficiency without broadening of contours of the image. This transfer sheet has feel and touch quite similar to those of ordinary paper and is very excellent in graphic characteristics.
