Abstract
A melt transfer web has a conformable layer which enables the melt transfer web to be used to transfer print uneven surfaces. In one embodiment the melt transfer web has a separate conformable layer and separate release layer. The conformable layer consists of copolymers of ethylene and vinyl acetate or copolymers of ethylene and acrylic acid which copolymers have a melt index greater than 30. The release layer consists of polyethylene films or ethylene copolymer films. In another embodiment a single layer of copolymers of ethylene and acrylic acid having a melt index between 100 and 4000 serves as a conformable-release layer.
Claims9
An improved melt transfer web for transferring vinyl ink to uneven contact surfaces, the web comprising:
- (a) a flexible substrate of a heat stable material having top and bottom surfaces;
- (b) a conformable polymeric film layer overlaying the top surface of the substrate and remaining attached thereto upon transfer of said vinyl ink to said uneven contact surfaces, said conformable polymeric film layer being comprised of a polymer selected from the group consisting of copolymers of ethylene and vinyl acetate and copolymers of ethylene and acrylic acid, wherein the copolymer has a melt index greater than 30, said conformable polymeric film layer allowing said vinyl ink to adapt to said uneven contact surfaces;
- and
- (c) a release polymeric film layer overlaying the conformable layer to receive and transfer said vinyl ink to said uneven contact surface, said release polymeric film being comprised of a polymer film selected from the group consisting of polyethylene films and ethylene copolymer films, said release polymeric film layer remaining attached to said conformable polymeric film layer upon transfer of said ink to said uneven contact surfaces.
An improved melt transverse web for transferring vinyl ink to uneven contact surfaces, the web comprising:
- (a) a flexible substrate of heat stable material having top and bottom surfaces;
- and
- (b) a conformable-release polymeric film layer overlaying the top surface of the substrate and comprised of a copolymer of ethylene and acrylic acid, wherein the copolymer has a melt index between 100 and 4000.
