Abstract
The present disclosure is drawn to print media, laminated decor products, and methods of making the same. In one example, a print medium can include an open paper substrate and a multivalent metal salt treatment applied to the open paper substrate at a multivalent metal salt loading into the open paper substrate at from 0.5 gsm to 5 gsm. The open paper substrate can include wood fiber including softwood fiber, hardwood fiber, or a blend of softwood fiber and hardwood fiber; binder including starch, protein, or hydrophilic polymer; and from 20 wt % to 50 wt % of TiO2.
Claims15
A print medium, comprising:
- an open paper substrate, comprising:
- wood fiber including softwood fiber, hardwood fiber, or a blend of softwood fiber and hardwood fiber,
- binder including starch, protein, or hydrophilic polymer, and
- from 20 wt % to 50 wt % of TiO2;
- and
- a multivalent metal salt treatment applied to the open paper substrate at a multivalent metal salt loading into the open paper substrate at from 0.5 gsm to 5 gsm.
A laminated decor product, comprising:
- a print medium, comprising;
- an open paper substrate including wood fiber, binder, and 20 wt % to 50 wt % of TiO2, and
- a multivalent metal salt coating applied to applied to the open paper substrate at a multivalent metal salt loading into the open paper substrate at from 0.5 gsm to 5 gsm;
- a digitally printed pigmented image applied to the print medium;
- and
- a resin applied to one or both surfaces of the print medium.
A method of preparing a print medium or laminated decor product, comprising:
- applying multivalent metal salt treatment to an open paper substrate to increase absorption capability of the open paper substrate, wherein the multivalent metal salt treatment provides a multivalent metal salt concentration to the open paper substrate at from 0.5 gsm to 5 gsm, the open paper substrate, comprising:
- wood fiber including softwood fiber, hardwood fiber, or a blend of softwood fiber and hardwood fiber,
- binder including starch, protein, or hydrophilic polymer binder, and
- from 20 wt % to 50 wt % of TiO2.
