Definitions

  • the present invention relates to new thermographic recording compositions, as well as the thermographic recording systems obtained from these compositions.
  • X represents H or a group having a labile H capable of forming a stable anion upon loss of an H + proton
  • M + represents a metal c
  • X represents H, -OH, (CH 2 ) m ⁇ OH. with 1 ⁇ m ⁇ 10, or: the hydrogen atom being particularly preferred.
  • these saccharin derivatives or their salts react with the color generator to give an irreversible coloring.
  • These two types of products are packaged on a medium (paper or other) which can be used in all devices with a thermal information display system: for example calculator printers, medical and industrial watch devices, fax machines, etc.
  • thermoreactive compositions All these uses have nothing to do with the use which is the subject of the present invention: developer of color generators in thermoreactive compositions.
  • thermoreactive compositions an entirely different family of compounds could be used as a developer in association with conventional dye precursors.
  • salts are obtained by direct reaction of the saccharin derivative with a suitable metal salt, thus, for example, the salts of the following metals: Cu, Cd, Co, Fe (II), Ni, Mn, Zn.
  • All these different constituents are ground, emulsified or dissolved in the medium and coated in one or more layers on a paper or other support (plastic for example).
  • a paper or other support plastic for example
  • the color generator and the color developer are ground separately, so as to avoid any premature reaction.
  • the two dispersions being mixed before coating in the case of a coating in one layer.
  • the nature, the grammage of the support, as well as the number and the thickness of the layers and their method of coating depend on the intended use, as well as on the desired effect, and are easily determined by a person skilled in the art. .
  • compositions are ground separately:
  • the paper After drying and calendering, the paper is used on a XEROX 485 fax machine. We obtain a good quality of restitution of the original, with black densities from 0.90 to 1.00. These densities are measured by reflection with a GAM RD 144 densitometer (WRATTEN filter No. 106).
  • compositions are ground separately: and: Then, the following mixture is prepared: which is coated at a rate of approximately 6.5 g / m 2 sec on a paper of 55 g / m 2 . After drying and calendering, this paper is used on an office calculating machine with thermal printer OLIVETTI LOGOS n ° 7.
  • the blue trace has a density of 1.0 (densitometer GAM RD 144, WRATTEN filter n ° 106).
  • the paper reaction threshold is very marked and is around 85 ° C.
  • composition is ground in a homogeneous manner:
  • This layer is deposited at a rate of 4 g / m 2 sec on a 55 g / m 2 paper support and then, after drying, the following composition, previously ground, is deposited over it, at a rate of approximately 3 g / m 2 sec. :
  • this paper After drying and possibly calendering, this paper is used in a device for recording EKGs of the "cardiopan 571" type from PHILIPS and makes it possible to obtain a very finely resolved black line, whatever the speed of the paper 50, 25 or 10 mm / s.
  • the density of the trace is 1.15 (GAM RD 144 densitometer, WRATTEN filter No. 106).
  • composition is ground in a homogeneous manner:
  • This layer is deposited at a rate of 4 g / m 2 on a Terphane polyester support from RHONE POULENC 100 ⁇ m thick. After drying, the following composition, deposited beforehand, is deposited over, at a rate of approximately 3 g / m 2 sec:
  • thermoreactive film After drying and possibly calendering, this thermoreactive film is tested on a “Thermotest device from the company SETARAM (LYON). We obtain red traces of density 1.4 (GAM RD 144 densitometer, green WRATTEN filter n ° 581). The reaction threshold for this paper is well marked and is around 85 ° C.
  • composition is dispersed in a homogeneous manner, after having ground the color-former and the saccharin separately, the other constituents being distributed equitably between the two grindings:
  • This layer is deposited on a paper of 50 g / m 2 at a rate of 6.5 g / m 2. After drying and calendering, this paper is used on a thermal printer ANDERSON-JACOBSON AJ 630 (10 characters per inch and 6 lines per inch) and allows us to obtain blue records with a density of 1.0 to 0.85, depending on the speed selected: 10, 15 or 30 characters per second (densitometer GAM RD 144, WRATTEN filter n ° 106) .
  • the reaction threshold is very marked and is around 95 ° C.
  • Example 2 This example is identical to Example 1, except that the saccharin ... 97 g is replaced in the grinding (1) by:
  • composition is ground in a homogeneous manner:
  • This composition is deposited at a rate of 4 g / m 2 sec on a 55 g / m 2 paper support. Then, after drying, the following composition, previously ground, is deposited over, at a rate of approximately 3 g / m 2 sec:
  • this paper After drying and calendering, this paper is used in an apparatus for recording electrocardiograms of the "Cardiopan 571" type from PHILIPS and makes it possible to obtain a dark brown trace very finely resolved, whatever the speed of movement of the paper: 50, 25 or 10 mm / s.
  • the density of the trace is 0.90 (densitometer GAM RD 144, WRATTEN filter n ° 106).
  • compositions are ground separately: Then the following mixture is prepared: which is coated, at a rate of approximately 6.5 g / m 2 sec, on a paper of 50 g / m 2. After drying and calendering, this paper is used on a desktop calculating machine with thermal printer HEWLETT-PACKARD 97 The slightly reddish black trace has a density of 1.15 (GAM RD 144 densitometer, WRATTEN filter n ° 106).
  • compositions have good light and storage stability under ambient temperature and humidity conditions, as well as under more severe conditions, at high humidity for example.
