Abstract
The present invention relates to articles having a printed surface as well as flexible coating and film compositions that are printable in combination with exhibiting stain resistance. The composition comprises a hard component having an elongation of less than about 150%, a soft component having an elongation of greater than about 200%, and a cross-linking agent. The hard component preferably comprises a thermoplastic polyurethane, acrylic polymer, polymeric polyol or mixture thereof. The soft component preferably comprises a thermoplastic urethane, polymeric polyol, or mixture thereof; whereas the cross-linking agent is preferably an isocyanate.
Claims66
An article comprising:
- a layer comprising the reaction product of:
- a hard polymeric component having an elongation up to about 150%;
- a soft component having an elongation ranging from about 200% to about 800% after cross-linking;
- and a cross-linking agent;
- and
- an ink on said layer.
An article comprising:
- a layer comprising the reaction product of:
- a hard component having an elongation up to about 150%;
- a soft component having an elongation ranging from about 200% to about 600% after cross-linking;
- and a cross-linking agent;
- wherein said layer is flexible, printable, and stain resistant.
An article comprising:
- a layer comprising a composition comprising:
- at least one first polymer having an elongation up to about 150%;
- at least one second polymer having an elongation ranging from about 200% to about 600%;
- and
- an ink on said layer.
A article comprising:
- a layer comprising a composition comprising:
- a first polymer having an elongation up to about 150%;
- a second polymer having an elongation ranging from about 200% to about 600%
- wherein said layer is flexible, printable, and stain resistant.
An article comprising a printable polymeric layer;
- wherein said polymeric layer is soluble in at least one solvent comprising acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, propylene glycol methyl ether acetate, ethyl acetate, propylene glycol methyl ether and mixtures thereof;
- and wherein said polymeric layer is flexible and stain resistant.
A composition comprising the reaction product of:
- a hard component comprising a first thermoplastic polyurethane polymer, an acrylic polymer, a polymeric polyol or mixture thereof;
- the hard component having functionality and an elongation up to about 150%;
- a soft component comprising at least one second thermoplastic polyurethane polymer having an elongation ranging from about 200% to about 600% after cross-linking, wherein the ratio of the hard component to soft component ranges from about 2:3 to 1:9;
- and at least one isocyanate.
