Abstract
Aspects of the present disclosure relate to a printable medium including a polyurethane dispersion. As an example, a printable medium may include a fabric base substrate, with an image-side and a back-side. A film-forming layer may be applied to the image-side of the fabric base substrate, including an anionic polyurethane dispersion having a reactive group on a backbone of the polyurethane dispersion and a reactive group on a capping unit of the polyurethane dispersion. An ink-receiving coating layer may be applied over the film-forming layer, including a crosslink agent.
Claims15
A printable medium, comprising:
- a fabric base substrate, with an image-side and a back-side;
- a film-forming layer, applied to the image-side of the fabric base substrate, including an anionic polyurethane dispersion having a reactive group on a backbone of the polyurethane dispersion and a reactive group on a capping unit of the polyurethane dispersion;
- and
- an ink-receiving coating layer, applied over the film-forming layer, including a crosslink agent.
A method for forming a printable medium comprising:
- providing a fabric base substrate, with an image-side and a back-side;
- applying a film-forming layer, on the image-side of the fabric base substrate, the film-forming layer including an anionic polyurethane dispersion having a reactive group on a backbone of the polyurethane dispersion and a reactive group on a capping unit of the polyurethane dispersion;
- and
- applying an ink-receiving coating layer, on the image-side of the fabric base substrate, over the adhesion promoting layer, including a crosslink agent.
A printing method comprising:
- obtaining a printable medium comprising:
- a fabric base substrate with an image-side and a back-side;
- a film-forming layer, applied to the image-side on the fabric base substrate, the film-forming layer including an anionic polyurethane dispersion having a reactive group on a backbone of the polyurethane dispersion and a reactive group on a capping unit of the polyurethane dispersion;
- and
- an ink-receiving coating layer, applied on the image-side, over the film-forming layer, including a crosslink agent;
- and
- applying an ink composition onto the printable medium to form a printed image.
