Abstract
A durable image is formed by the combination of an aqueous ink comprising an aqueous vehicle and a colorant; and a textile, wherein said textile has been treated with a hydrophilic composition containing at least one crosslinkable thermoplastic polymer, said crosslinkable polymer having a number average molecular weight of at least 6,000 and being selected from the group consisting of polymers having at least one carboxylic acid group and at least one crosslinkable group; and a mixture of at least two polymers wherein at least one has a carboxylic acid group and at least one other has a crosslinkable group.
Claims11
An ink jet ink/textile combination comprising:
- a) an aqueous ink comprising an aqueous vehicle and a colorant;
- and
- b) a textile, wherein said textile has been treated with a hydrophilic composition containing at least one crosslinkable thermoplastic polymer, said crosslinkable polymer having a number average molecular weight of at least 6,000 and being selected from the group consisting of
- 1) polymers having at least one carboxylic acid group and at least one crosslinkable group;
- and
- 2) a mixture of at least two polymers wherein a first polymer has at least carboxylic acid group and a second polymer has at least one crosslinkable groups
- wherein said ink is printed on said textile to form an image.
A process for forming a durable printed image on a textile comprising, in sequence:
- a) providing a textile, wherein said textile has been treated with a hydrophilic composition containing at least one crosslinkable thermoplastic polymer, said crosslinkable polymer having a molecular weight of at least 6,000 and being selected from the group consisting of
- 1) polymers having both carboxylic acid groups and a crosslinkable group and
- 2) a mixture of at least two polymers wherein at least one has a carboxylic acid group and another has a crosslinkable group;
- b) printing an aqueous ink image on a textile;
- and
- c) heating the printed image to a temperature in the range of approximately 100 to 190.degree. C. for about 5 seconds to 30 minutes to sequentially (1) soften said hydrophilic thermoplastic polymer and encapsulate the ink colorant, and (2) cross-link said polymer to form a hydrophobic matrix.
