what is the normal weight of thermal paper?12.156.194.3 20:59, 31 October 2007 (UTC)
The weight-do you mean substance? It's substance is about 40, 50, 55, 60, 65, 70 to 90 gsm. Is there anybody know it's HS code? Newone (talk) 07:40, 4 April 2008 (UTC)
"The Silent 700 was the first thermal print system that printed on thermal paper."
Well, yes, of course. By definition, any flexible surface that's printed on thermally is "thermal paper". (I doubt there were systems for thermal printing on, say, tin can lids.)
If there was some other form of thermal printing that used sensitized paper that could not reasonably be called "thermal paper", then there should be a reference to it.
3M at one time made a copying system that used a silver-based thermally activated transfer sheet. But it was not a printing system in the common meaning of the word. WilliamSommerwerck (talk) 23:44, 6 August 2010 (UTC)
Well, I believe there are Thermal Transfer systems that print via thermal heating of a ribbon that then transfers wax or resin to the surface of the media. This did not require a 'thermal paper'as described in this article, and could in fact be used to print on tin can lids if you chose. By the way, there are thermal media which would fit your 'flexible surface' requirement above that are not made of paper at all, but rather of polyethelene.
So... not so Duh after all. —Preceding unsigned comment added by 72.46.228.155 (talk) 12:07, 6 April 2011 (UTC)
The sentence: The surface of the paper is impregnated with a solid-state mixture of a dye and a suitable matrix; Does not make much sense, I presume that the word matrix is supposed to be acid... 89.248.248.27 (talk) 10:10, 22 November 2010 (UTC)
As someone with extensive experience in the industry, I can confirm this statement is absolutely false. The vast majority of thermal paper (especially thermal paper used in sales receipts) is NOT topcoated, nor is a topcoat required in "most cases". The bulleted points are correct about the benefits of topcoating, but the insinuation that a topcoat is required is patently false.
I'm going to look for some reputable sources before I make any changes to the article though, obviously. 173.78.6.64 (talk) 19:38, 20 November 2013 (UTC)
Cyberbot II has detected links on Thermal paper which have been added to the blacklist, either globally or locally. Links tend to be blacklisted because they have a history of being spammed or are highly inappropriate for Wikipedia. The addition will be logged at one of these locations: local or global If you believe the specific link should be exempt from the blacklist, you may request that it is white-listed. Alternatively, you may request that the link is removed from or altered on the blacklist locally or globally. When requesting whitelisting, be sure to supply the link to be whitelisted and wrap the link in nowiki tags. Please do not remove the tag until the issue is resolved. You may set the invisible parameter to "true" whilst requests to white-list are being processed. Should you require any help with this process, please ask at the help desk.

Some say it fades on purpose. A built-in Statute of Limitations perhaps. Else one would wonder why in today's high tech society would it still be used? Jidanni (talk) 05:54, 11 June 2019 (UTC)
If the technology is explained by the documents in the reference section I think that there should be a number leading to the correct one, also the chemistry section should be expanded to include other non-leuco dye processes, for the sake of knowledge and also since the growing concern in regards of bisphenol A and similar components (often present into the leuco-dye processes) there is a possibility to bring back alternative chemistries in countries who prohibit the use of such chemicals, making relevant that information again 37.183.116.84 (talk) 16:54, 11 June 2023 (UTC)
what are the querendo reactions that happen when the paper is exposed to uv light or hear or humidity or friction, that make the dye want to recrystallize into its non-colored state?
For what I understand when the chemicals mix together they wouldn't unmix, so why? How can heat, the think that makes it be printable, makes it go back to not-printed? Vhoyer (talk) 11:18, 18 April 2024 (UTC)
