Abstract
A receptor element for non-impact printing is provided comprising a support and an image receiving layer containing at least 80% by weight with respect to the total weight of the layer of a polymer with between 0.5 and 20 mole % of moieties carrying sulphonic acid groups. Preferably the polymer is a polyester comprising between 0.5 and 20 mole % with respect to the total acid content of moieties provided by sulphoisophthalic acid and the sulpho groups are present in free acid form.
