- ESCA photoelectron spectroscopy
- the content is less than 5 atomic%, excellent writing and non-slip properties can be obtained, but the ink layer is excessively transferred during thermal transfer printing, making it difficult to accurately record and determine the intended information. It is not preferable because the adhesive layer is hardly peeled off from the release sheet because the peeling force is too heavy, the adhesive layer is hardly rewound with an adhesive tape, and furthermore, it cannot be used because it cannot be rewound. On the other hand, if it exceeds 30 atom%, there are problems such as insufficient writing performance, printability by heat transfer method, and non-slip property, or the adhesive layer is easily peeled off from the release sheet. Not preferred.
