Abstract
This invention provides an improved method for sublimation dye transfer printing of a sublimable dye onto fabric by applied heat, comprising applying a composition comprising a polyester resin to the fabric, in which the polyester resin chemically bonds the dye to the fabric, to yield a fabric having a soft hand and deep color which is fast through repeated laundering. In preferred embodiments, the polyester resin has free carboxyl groups. In another embodiment, a conventional dye binder is also applied to the fabric. In a further modification, metallic glitter is added to the dye. The present invention also provides dye bonding compositions for bonding sublimable dyes to fabrics, and sublimation dye transfer printing elements incorporating the compositions of the invention.

In a one step method for sublimation dye transfer printing of a sublimable dye onto fabric by applied heat from a sublimation dye transfer paper the improvement comprising applying a composition comprising a polyester resin having free carboxyl groups, a hardener and a dye binder which is a polymer of one or more monomers selected from the group consisting of unsaturated aliphatic hydrocarbons, acrylic acid esters, methacrylic acid esters, vinyl chloride, vinyl propionate, vinyl isobutyl ether, vinyl acetate, styrene and acrylonitrile, by transfer from the sublimation dye transfer paper to the fabric, in which the polyester resin securely bonds the dye to the fabric to yield a fabric having a soft hand and deep color which is fast to repeated laundering.
A sublimable dye transfer printing composition for transfer of the dye onto a fabric by applied heat which comprises a polyester resin having free carboxyl groups, a dye binder and a hardener, said polyester resin securely bonding the dye to the fabric to yield a dyed fabric having soft hand and color fastness after repeated laundering, where said dye binder is a polymer of one or more monomers selected from the group consisting of unsaturated aliphatic hydrocarbons, acrylic acid esters, methyl acrylic acid esters, vinyl chloride, vinyl propionate vinyl isobutyl ether, vinyl acetate, styrene and acrylonitrile.
A sublimation dye transfer element for applying a heat sublimable dye to a permanent substrate comprising:
- (a) a temporary supporting substrate;
- (b) a sublimable dye supported by the temporary substrate;
- (c) a layer comprising a mixture of a polyester resin having free carboxyl groups and a polyethylene emulsion release agent supported by the dye;
- and
- (d) a layer containing a dye binder and a hardener disposed on the layer comprising said polyester resin and release agent, where the dye binder is a polymer of one or more monomers selected from the group consisting of unsaturated aliphatic hydrocarbons, acrylic acid esters, methyl acrylic acid esters, vinyl chloride, vinyl propionate, vinyl isobutyl ether, vinyl acetate, styrene and acrylonitrile.
In a one step method for sublimation dye transfer printing of a sublimable dye onto fabric by applied heat from a sublimation dye transfer paper, the improvement comprising applying a composition comprising a polyester resin having free carboxyl groups and a hardener selected from the group consisting of isocyanates, epoxides, melamine-formaldehyde and urea-formaldehyde by transfer from the sublimation dye transfer paper to the fabric, in which the polyester resin securely bonds the dye to the fabric to yield a fabric having a soft hand and deep color which is fast to repeated laundering.
A sublimable dye transfer printing composition for transfer of the dye onto a fabric by applied heat which comprises a polyester resin having free carboxyl groups, a dye binder and a hardener, selected from the group consisting of isocyanates, epoxides, melamine-formaldehyde and urea-formaldehyde, said polyester resin securely bonding the dye to the fabric to yield a dyed fabric having soft hand and color fastness after repeated laundering, where said dye binder is a polymer of one or more monomers selected from the group consisting of unsaturated aliphatic hydrocarbons, acrylic acid esters, methyl acrylic acid esters, vinyl chloride, vinyl propionate, vinyl isobutyl ether, vinyl acetate, styrene and acrylonitrile.
A sublimation dye transfer element for applying a heat sublimable dye to a permanent substrate comprising:
- (a) a temporary supporting substrate;
- (b) a heat sublimable dye supported by the temporary substrate;
- (c) a layer of polyester resin having free carboxyl groups supported by the dye;
- and
- (d) a layer containing a dye binder and a hardener disposed on the layer of the polyester resin, where the dye binder is a polymer of one or more monomers selected from the group consisting of unsaturated aliphatic hydrocarbons, acrylic acid esters, methyl acrylic esters, vinyl chloride, vinyl propionate, vinyl isobutyl ether, vinyl acetate, styrene and acrylonitrile, and said hardener is selected from the group consisting of isocyanates, epoxides, melamine-formaldehyde and urea-formaldehyde.
In a one step method for sublimation dye transfer printing of a sublimable dye onto fabric by applied heat from a sublimation dye transfer paper, the improvement comprising applying a composition comprising a polyester resin having free carboxyl groups and triglycidylisocyanurate hardener by transfer from the sublimation dye transfer paper to the fabric, in which the polyester resin securely bonds the dye to the fabric to yield a fabric having a soft hand and deep color which is fast to repeated laundering.
