Abstract
According to one aspect, a printing composition of the present application comprises from about 10.00% to about 14.00% by weight of a pigment, from about 3.00% to about 7.00% by weight of a polymer, from about 15.00% to about 19.00% by weight of a co-solvent, from about 0.20% to about 0.40% by weight of a surfactant, and water.
Claims13
A water-based printing composition for printing on a heat-shrinkable substrate, comprising:
- from about 10.00% to about 14.00% by weight of a titanium dioxide pigment;
- from about 3.00% to about 7.00% by weight of a polymer;
- from about 15.00% to about 19.00% by weight of a co-solvent, wherein the co-solvent is 3-methoxy-3-methyl-1-butanol;
- from about 0.20% to about 0.40% by weight of a surfactant;
- and
- at least 50.00% water;
- the water-based printing composition having a surface tension of at least 31.0 dynes/cm;
- wherein the co-solvent has an evaporation profile that allows drying and adherence of the printing composition applied to the heat-shrinkable substrate at a temperature up to the threshold for dimensional integrity of the heat-shrinkable substrate.

A method of printing on a heat-shrinkable substrate, comprising:
- providing a heat-shrinkable substrate;
- applying a water-based printing composition to a surface of the substrate, the printing composition comprising from about 10.00% to about 14.00% by weight of a titanium dioxide pigment, from about 3.00% to about 7.00% by weight a of polymer, from about 15.00% to about 19.00% by weight of a co-solvent, wherein the co-solvent is 3-methoxy-3-methyl-1-butanol, from about 0.20% to about 0.40% by weight of a surfactant, and at least 50.00% water;
- and
- drying the substrate, wherein the substrate remains below a temperature such to not exceed a threshold for dimensional integrity of the substrate;
- the water-based printing composition having a surface tension of at least 31.0 dynes/cm;
- wherein the co-solvent has an evaporation profile that allows drying and adherence of the printing composition applied to the heat-shrinkable substrate at a temperature up to the threshold for dimensional integrity of the heat-shrinkable substrate.
