Carrier paper
A carrier paper has a coating applied thereon, which serves to take up ink which is then applied using a thermal sublimation printing process to a textile or a coated hard substrate. The textile, the hard substrate coating, or both are made from a polyester-containing plastic. The coating on the carrier paper comprises a semisynthetic polymer and the coated carrier paper is placed in direct contact with the textile or with the coated hard substrate during sublimation transfer. In the case of such a carrier paper, it is intended according to some aspects of the present invention that the semisynthetic polymer has thermoplastic properties. In the case of such a carrier paper, ghosting can be permanently avoided without adversely affecting primary parameters, such as printability, drying and transfer property of the carrier paper.
1. A sublimation transfer system, comprising:
a carrier paper;
a carrier paper coating disposed on at least one side of the carrier paper; and
an image comprised of thermal sublimation ink applied to the coated side of the coated carrier paper; wherein the carrier paper coating comprises a semisynthetic polymer having thermoplastic properties.
2. The sublimation transfer system as claimed in claim 1 , wherein the semisynthetic polymer is ethylcellulose, thermoplastic starch (TPS®), or methylhydroxypropylcellulose (MHPC).
3. The sublimation transfer system as claimed in claim 1 , wherein the semisynthetic polymer is hydroxypropylcellulose (HPC).
4. The sublimation transfer system as claimed in claim 3 , wherein the carrier paper coating comprises from 5 to 60% by weight of semisynthetic polymer.
5. The sublimation transfer system as claimed in claim 1 , wherein the carrier paper coating comprises from 5 to 60% by weight of semisynthetic polymer.
6. The sublimation transfer system as claimed in claim 1 , wherein the semisynthetic polymer is ethylcellulose having a high degree of etherification.
