Assess the multifrequency nature of each in control group and dye image receiving layer composite of the present invention and gained heat picture receiver element in the following manner.
coating quality:
Visual assessment coating quality (amplification) and one that provides in Three Estate.The vision grade of " not good " mean through coating and dry image receiving layer be uneven because visible coating lines and net (speckle) is extremely outstanding." can " vision grade mean that some coating lines and net be obvious but dry image receiving layer quality are acceptable.The visual assessment of " well " means that dry image receiving layer is for extremely evenly glossy and smooth, without obvious visible coating lines or net.
donor-receiver adhesion:
" printing " or form donor element and heat picture receiver element hot assembly after, visual assessment donor-receiver quality of adhesion (amplification).The assessment of " not good " means dyestuff the donor layer general and donor element supporter layering in thermal dye transfer (printing) period in donor element." can " assessment mean dyestuff donor layer not with the layering of donor element supporter, but there is chatter noise in printer and there are some flutter lines in the hot dye transfer image of some gained.The assessment of " well " means in the hot dye transfer image of gained without defect of significantly adhering.
gTG transition:
The level and smooth gradual transition of optical density is concerning most important high-quality height light prints.Therefore, measured by the GTG transition of following visual assessment (without amplify) in lower optical densities region (as in the situation that prints at high light): measure 18 optical density levels increased progressively from minimum density (D minimum, or energy level 18) to maximal density (D maximum>1.5 or energy level 1) density continuity, and observe under maximal density level (level x) specific image lose or optical density discontinuous, this also effectively can illustrate in sensitometric curve (that is, optical density is to energy level) and relevant sensitization data.
The assessment of " not good " means obtained level x and level 18 (or D minimum) between optical density difference, i.e. Δ OD<0.015, or based on sensitometric curve, level x and level 18 (or D minimum) between least square slope <0.002 (absolute value)." can " assessment mean obtained level x and level 18 (or D minimum) between optical density difference (Δ OD) be at least 0.010 to 0.058, or based on sensitometric curve, level x and level 18 (or D minimum) between least square slope be at least 0.002 to 0.006 (absolute value).The assessment of " well " means obtained level x and level 18 (or D minimum) between optical density difference, i.e. Δ OD>0.042, or based on sensitometric curve, level x and level 18 (or D minimum) between least square slope >0.006 (absolute value).
the D of muted color (redness of muted color, green or blueness) maximum :
As in the practice of the invention use, the D of muted color maximumfor the target maximum optical density of neutralc tint is measured, it can use given one group of dyestuff donor element, heat picture receiver element and hot print condition to obtain from imaging hot print.Because target neutralc tint, the D of muted color maximumthe tertiary colour of the yellow of the hot transfer printing of origin self-corresponding color dye donor element block, carmetta and cyan dye is formed, so Ge Ruida Macbeth (GretagMacbeth) spectral scan machine can be used to obtain the optical density of corresponding color dye respectively in the heat picture printed, i.e. D maximum(redness of muted color), D maximum(green of muted color) and D maximum(blueness of muted color).In the result of showing in hereafter Table III, less absolute value is better, because its display color of image is from D maximumunder the skew of target optical density less, and color image is therefore comparatively close to target optical density.
These assessment results are provided in following Table III.It is evident that from these results, although the quality that contrast composite and heat picture receiver element provide some good, it does not provide all desirable characteristics all the time.But composite of the present invention and heat picture receiver element provide the results needed of the characteristic of great majority needed for (if not all).
Specifically, it is evident that, when there is not film-forming polyesters, coating quality (result as film forming characteristics) and as list as follows in Table III as the adhesion of donor-receiver, print uniformity and dye transfer efficiency (as D maximum) total printing (image) performance usually to degenerate and not too satisfactory as better quality coloured image.For example, when comparing control group C3 to control group C5, I1 of the present invention to I3 of the present invention and I30 of the present invention to I32 of the present invention, compared to example of the present invention, the coating quality of control group and donor-receiver adhesive performance not good.Control group C8 to control group C23 and control group C-28, I6 of the present invention to I18 of the present invention and I25 of the present invention to I50 of the present invention relatively in, all examples show good donor-receiver adhesiveness, but the D of control group example maximumvalue is obviously than the D of example of the present invention maximumit is poorer to be worth.
When there is not acrylic based emulsion (control group C1 and control group C2), donor band (element) is not separated easily during hot print process, the heat picture receiving element and it is tightly adhered usually, causes serious printing and print quality problem.In addition, the image receiving layer of control group C1 usually adheres on the opposite flank of heat picture receiver element, especially when its be roll form or in section stacking form time.
Control group C1 (non-mold release agent) and control group C2 (having releasing agent) relatively show the existence of water dispersible releasing agent in image receiving layer composite reduce hot print process during donor element to the adhesion of heat picture receiver element.
When crosslinking agent is present in dye image receiving layer composite; donor-receiver adhesion problems (donor-receiver release characteristics of raising) reduces to make releasing agent required in image receiving layer less; this helps the adhesion of the raising promoted between transparent laminating protective film and image receiving layer conversely, and it is the characteristic needed.
Table III
" NA " means the adhesion due to donor-receiver, and datum level is unavailable.
