Definitions

  • This invention relates to a thermal image receiver element that has an aqueous-based image receiving layer. This invention also relates to a method for making this thermal image receiver element as well as method for using it to provide a dye image by thermal transfer from a donor element. BACKGROUND OF THE INVENTION
  • thermal transfer systems have been developed to obtain prints from pictures that have been generated from a camera or scanning device. According to one way of obtaining such prints, an electronic picture is first subjected to color separation by color filters. The respective color- separated images are then converted into electrical signals. These signals are then transmitted to a thermal printer. To obtain the print, a cyan, magenta or yellow dye donor element is placed face-to-face with a thermal image receiver element. The two are then inserted between a thermal printing head and a platen roller. A line-type thermal printing head is used to apply heat from the back of the dye-donor sheet. The thermal printing head has many heating elements and is heated sequentially in response to one of the cyan, magenta or yellow signals. The process is then repeated for the other colors. A color hard copy is thus obtained which corresponds to the original picture viewed on a screen.

  • a visual rating of "poor” means that the coated and dried image receiving layer was not uniform as coating lines were visible and reticulation (mottle) was very prominent.
  • a visual rating of "OK” means some coating lines and reticulation were evident but the dry image receiving layer quality was acceptable.
  • a visual evaluation of "Good” means that the dry image receiving layer was very uniformly glossy and smooth with no visibly noticeable coating lines or reticulation.
  • the donor-receiver sticking quality was visually evaluated (without magnification) after "printing” or forming the thermal assembly of donor element and thermal image receiver element.
  • An evaluation of “poor” means that the dye donor layer in the donor element generally delaminated from the donor element support during thermal dye transfer (printing).
  • An evaluation of "OK” means that dye donor layer did not delaminate from the donor element support, but there was chattering noise in the printer and some chatter lines in some of the resulting thermally transferred dye images.
  • An evaluation of "Good” means that no sticking defects were evident in the resulting thermally transferred dye images.
  • Grey-scale Transition :
  • a smooth gradual transition of optical density is critical for a quality highlight print. Therefore, a measure of grey-scale transition at a low optical density region, such as, in the situation of a highlight printing, was visually evaluated (without magnification) by determining the density continuity over 18 incremental optical density steps from minimum density (D m i n , or energy step 18) to maximum density (D max >1.5 or energy step 1) and at which step (step x) the particular image was lost or discontinuity in optical density was observed, which can also be illustrated effectively in a sensitometric curves, that is, optical density vs. energy steps, and the associated sensitometric data.
  • An evaluation of "Poor” means that a difference in optical density, that is, AOD ⁇ 0.015 between step x and step 18 (or D min ), or a least-square slope that is ⁇ 0.002 (absolute value) based on the sensitometric curve between step x and step 18 (or D m i n ), was obtained.
  • An evaluation of "OK” means that an optical density difference (AOD) of at least 0.010 to 0.058 between step x and step 18 (or D m i n ), or a least-square slope at least 0.002 to 0.006 (absolute value) based on the sensitometric curve between step x and step 18 (or D m i n ), was obtained.
  • Dm a x of Neutral (Red, Green, or Blue of Neutral):
  • of Neutral is a measure of an aim maximum optical density of a neutral hue that can be obtained from an imaged thermal print using a given set of dye donor elements, thermal image receiver elements, and thermal printing conditions.
  • the aim neutral hue, D max of Neutral is composed of a composite of the thermally transferred yellow, magenta, and cyan dyes from respective color dye donor element patches, the optical density of the respective color dye, that is D max (Red of Neutral), Dm a x (Green of Neutral), and D max (Blue of Neutral), can be obtained separately in the printed thermal images using a Gretag Macbeth SpectroScan machine.
  • the smaller absolute values are better because they show a smaller deviation of the image color from the aim optical density at D ⁇ , and the color images are thus closer to that aim optical density.
  • Controls CI and C2 When the acrylic latex was not present (Controls CI and C2), the donor ribbon (element) did not separate easily during the thermal printing process and it usually stuck tightly to the thermal image receiving element, causing serious printing and print quality problems. In addition, the image receiving layer of Control CI tended to adhere to the opposite side of the thermal image receiver element, particularly when it was in roll form or in cut sheet stacked format. A comparison of Control CI (no release agent) and Control C2 (release agent) indicates that the presence of a water-dispersible release agent in the image receiving layer formulation reduces sticking of the donor element to the thermal image receiver element during the thermal printing process.
  • the donor-receiver sticking problem improved the donor-receiver release property
  • less release agent was required in the image receiving layer, which in turn helps promote an improved adhesion between the clear laminate protective film and the image receiving layer, which is a desirable property.

Abstract

La présente invention concerne la réception d'une image sèche par un élément de récepteur de thermogramme dont la couche externe a une Tg d'au moins 25 °C au niveau de la couche la plus externe. La couche de réception d'image sèche possède une épaisseur à sec d'au moins 0,5 µm et jusqu'à 5 µm inclus. Elle comprend une matrice de liant polymère constituée essentiellement de : (1) un polymère acrylique hydrodispersible comprenant des groupes chimiques réagis ou non réagis hydroxy, phospho, phosphonate, sulfo, sulfonate, carboxy ou carboxylate, et (2) un polyester hydrodispersible de Tg inférieure ou égale à 30 °C. Le polymère hydrodispersible est présent à une teneur d'au moins 55 % en poids du poids total de la couche de réception d'image sèche et à rapport sec par rapport polyester hydrodispersble d'au moins 1 : 1 et jusqu'à 20:1 inclus. L'élément de récepteur de thermogramme peut être utilisé pour préparer des thermogrammes secs après transfert thermique depuis un élément donneur thermique.
