Compositions and methods for treating a substrate and for improving adhesion of an image to a treated substrate

A printed material exhibiting improved adhesion of an image to a treated substrate, comprising:

• a treated substrate, comprising;
• a substrate, and
• a coating disposed on the substrate and formed from a water-based composition comprising a binder, a binder additive, and an aluminum salt wherein the binder additive comprises a polymer, the polymer comprises at least one repeating unit, and the at least one repeating unit comprises a tertiary amide group;
• and
• an image disposed on the treated substrate and formed from a liquid toner,
• wherein the treated substrate has a first side and a second side opposite the first side, and wherein each of the first side and the second side, independently, comprise:
• the binder additive in an amount of from about 0.0075 to about 0.375 g/m2 based on a total weight of the substrate on a dry weight basis;
• the aluminum salt in an amount of from about 0.0075 to about 0.375 g/m2 based on a total weight of the substrate on a dry weight basis;
• or
• a combination thereof.

A method for improving adhesion of an image to a treated substrate, the method comprising:

• providing a substrate;
• applying a water-based composition to the substrate to form a treated substrate, the composition comprising;
• binder,
• a binder additive comprising a polymer, the polymer comprising at least one repeating unit, and the at least one repeating unit comprising a tertiary amide group, and
• an aluminum salt;
• and
• applying a liquid toner to the treated substrate to form the image on the treated substrate,
• wherein the treated substrate has a first side and a second side opposite the first side, and wherein each of the first side and the second side, independently, comprise:
• the binder additive in an amount of from about 0.0075 to about 0.375 g/m2 based on a total weight of the substrate on a dry weight basis;
• the aluminum salt in an amount of from about 0.0075 to about 0.375 g/m2 based on a total weight of the substrate on a dry weight basis;
• or
• a combination thereof.

A method for improving adhesion of an image to a treated substrate, the method comprising:

• providing a paper product;
• applying a water-based composition to the paper product to form a treated paper product, the composition comprising;
• binder,
• a binder additive comprising a polymer, the polymer comprising at least one repeating unit, and the at least one repeating unit comprising a tertiary amide group, and
• an aluminum salt;
• and
• applying a liquid toner to the treated paper product to form the image on the treated paper product,
• wherein:
• the binder additive is applied to the paper product in an amount of from about 0.02 to about 1 wt. % based on a total weight of the paper product on a dry weight basis;
• the aluminum salt is applied to the paper product in an amount of from about 0.02 to about 1 wt. % based on a total weight of the paper product on a dry weight basis;
• or
• a combination thereof.
