PROCESS FOR SUBLIMATION TRANSFERRING A PATTERN ON POLYURETHANE SURFACE AND POLYURETHANE PRODUCT TRANSFERRED THEREFROM

摘要

This invention relates to a process for sublimation transferring a pattern on polyurethane surface and polyurethane products transferred therefrom. When a wet-dry or dry polyurethane surface was subjected to sublimation transfer the polyurethane surface adhered to the transfer paper due to the elevated temperature. Thus it was impossible to separate the polyurethane surface form the transfer paper. To solve this problem of the prior art, one-component polyurethane is mixed with solvents to make the mixture a liquid, and drying it gives polyurethane products. As shown in Figure 5a, the polyurethane surface can be easily separated from the transfer paper.
