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) a thermoplastic acrylic polymer having a carboxyl group content of 2 to 30% by weight and (B) a thermosetting resin reactive with the acrylic polymer (A), and a process for preparing this transfer sheet by using an aqueous coating composition are 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.
