  • Receiving element with cellulose paper support for use in thermal dye transfer
    Patent number: 5288690
    Abstract: Dye-receiving elements for thermal dye transfer are disclosed comprising a cellulose fiber paper support having thereon a dye image-receiving layer. The cellulose fibers of the paper support are fibers of hardwood varieties selected from those a) having a length weighted average fiber length equal to or less than about 0.5 mm as measured after pulping and bleaching or b) pulped by the sulfite process. The paper supports have a specific bending stiffness of less than about 0.4 Nm.sup.7 /kg.sup.3 for paper prepared on a continuous Fourdrinier wire machine as measured in the machine direction.
    Type: Grant
