  • Polyester resin and sublimation transfer image receiver using same
    Patent number: 6048822
    Abstract: A polyester resin having a glass transition temperature of not less than 15.degree. C. and a reduced viscosity of 0.15-1.5, which comprises a graft polymer comprising a polyester having an unsaturated bond as a main chain, and a radical polymerizable unsaturated monomer as a side chain, and a sublimation transfer image receiver which comprises a dyeable layer mainly comprising a dyeable resin comprising the polyester resin. Inasmuch as the polyester resin can provide highly sensitive images without the use of a plasticizer or an additive, it is suitable as a dyeable resin for a sublimation transfer image receiver. The images obtained by the use of a sublimation transfer image receiver having a dyeable layer containing this resin are superior in durability and preservation stability.
