Abstract
A receiver sheet for thermal transfer printing comprises a substrate having a dye-receiving side and a backcoat on the other side, characterised in that the major component of the backcoat is a partially esterified styrene/maleic anhydride copolymer. This provides a surface which can readily be written on using aqueous inks or ball pens, and can be adhered to by water-activated adhesives. It is also resistant to retransfer of dye from an underlying print, e.g. during storage. The backcoat may also contain antistatic agents and fine inert particles to improve handling properties, appearance and tooth.
