replies: text: Don't know HS code. The normal weight is 58gsm.203.160.1.72 (talk) 03:59, 15 August 2008 (UTC)
replies: text: I realize this comment is old, but typical weight for thermal paper is now 48-50GSM, depending on the manufacturer. Obviously needs a source, but as someone with plenty of experience in the industry, that's the standard. 173.78.6.64 (talk) 03:38, 29 October 2013 (UTC)

message: "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)
thread_title:  Duh... 

message: 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)
replies: text: It should say a dye, and acid (at least in the example given), and a matrix. The matrix is the thing that holds the dye and the acid, and that can melt to let them mix. The dye has no color until it reacts with the acid. --Itub (talk) 12:31, 13 July 2012 (UTC)
thread_title:  Mistake? 

message: 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.

message: 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)
thread_title:  Fade on purpose 

message: 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)
thread_title:  Missing explanation and reference number for "3M metallic salt technology" 

message: 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)
