Definitions

  • imaging system employs a layer of photosensitive microcapsules.
  • the microcapsules are prepared by microencapsulating a free radical polymerizable composition which contains an electron donating color precursor.
  • the image system assumes two forms.
  • the imaging system is a transfer system in which a support carrying a layer of photosensitive microcapsules is image-wise exposed to radiation and assembled with a developer sheet, e.g., a sheet containing a layer of a Lewis acid such as a phenolic resin.
  • the imaging system is a self-contained imaging system in which the photosensitive microcapsules and the Lewis acid are carried on the surface of a common substrate in one layer or in juxtaposed layers.
  • a layer containing photosensitive microcapsules and a developer material is interposed between two plastic films, at least one of which is transparent. Using a combination of an adhesive and a subbing layer, the films are permanently sealed to provide a film unit. This construction is advantageous because it prevents the chemical reactants in the imaging system from coming into contact with the user.
  • the imaging system is preferably a full color imaging system in which three different sets of microcapsules are used in combination and each set of microcapsules is sensitive to a distinct wavelength band.
  • This full color system is described in U.S. Patent 4,842,976.
  • three sets of microcapsules respectively containing cyan, magenta and yellow color precursors are respectively sensitive to red, green and blue light are employed.
  • these microcapsules are sensitized using a so-called "dye-borate photoinitiator" of the type described in U.S. Patent 4,772,530 to Gottschalk.
  • photoinitiators in one embodiment, are complexes of cationic cyanine dyes and a boranyl anion such as a triphenylbutylboranyl anion.
  • a boranyl anion such as a triphenylbutylboranyl anion.
  • printers can be designed which employ radiation sources which emit at wavelengths outside the visible spectrum, for example, in the infrared region. This presents an opportunity to minimize the problems associated with cross-talk since it is no longer necessary to restrict the sensitivity range of a photosensitive material to the visible region, the sensitivity of the imaging system can be extended into the infrared region at one end of the spectrum and optionally the ultraviolet region at the other end.
  • the foregoing imaging system and, more particularly, the imaging system described in U.S. Patent 4,772,530 is modified to include one or more infrared photosensitive compositions and, more particularly, to include one or more photosensitive compositions in which the photoinitiator is a complex between an infrared-sensitive dye and a boranyl anion of the type mentioned above.
  • one embodiment of the invention resides in an imaging system comprising a support having a layer of at least one set of photosensitive microcapsules on the surface thereof, said microcapsules being sensitive to distinct band of radiation and containing a complex of an infrared sensitive cationic dye and a boranyl anion.
  • the imaging system includes cyan forming, magenta forming and yellow forming capsules and at least one set of capsules includes an infrared sensitive dye borate compound as a photoinitiator.
  • at least one other set includes a visible light sensitive dye borate compound or an ultraviolet initiator.
  • all three sets of microcapsules contain a photohardenable composition containing a complex of a cationic infrared sensitive dye and a boranyl anion.
  • infrared-sensitive photoinitiators which can be employed in the imaging system of the present invention are described in Japanese Published Applications 3- 221506; 4-261405; 8-100011; 8-100012; and 8-34808, all of which are incorporated herein by reference for a description of the cationic dyes and methods for obtaining the photoinitiators.
  • a table of the infrared sensitive cationic dyes described in the aforementioned patents is provided in the following Table 1 where "Ph" indicates a phenyl group:
  • the infrared dyes in Table 1 are complexed with a borate anion.
  • a borate anion Any of the borate anions described in U.S. Patent 4,772,530 can be used in this invention.
  • the preferred boranyl anion is a triphenyl n-butylboranyl anion.
  • the anions can be represented by the general formula (I):
  • R 1 , R 2 , R 3 , and R 4 are independently selected from the group consisting of alkyl, aryl, alkaryl, allyl, aralkyl, alkenyl, alkynyl, alicyclic and saturated or unsaturated heterocyclic groups.
  • triphenylalkylborate and trianisylalkylborate anions such as triphenylbutylborate and trianisylbutylborate anions because they readily dissociate to triphenylborane or trianisylborane and a butyl radical.
  • tetrabutylborate anion does not work well presumably because the tefrabutylborate radical is not stable and it readily accepts an electron back from the dye in a back electron transfer and does not dissociate efficiently.
  • tetraphenylborate anion is very poor because the phenyl radical is not easily formed.
  • R 1 , R 2 , R 3 , and R 4 is an alkyl group.
  • R 1 , R 2 , R 3 , and R 4 is an alkyl group.
  • R 1 , R 2 , R 3 , and R 4 can contain up to 20 carbon atoms, and they typically contain 1 to 7 carbon atoms. More preferably R'-R 4 are a combination of alkyl group(s) and aryl group(s) or aralkyl group(s) and still more preferably a combination of three aryl groups and one alkyl group.
  • alkyl groups represented by R'-R 4 are methyl, ethyl, propyl, butyl, pentyl, hexyl, octyl, stearyl, etc. and can be straight or branched chain and possibly cyclic.
  • the alkyl groups may be substituted, for example, by one or more halogen, cyano, acyloxy, acyl, aryl, alkoxy or hydroxy groups.
  • aryl groups represented by R0R 4 include phenyl, naphthyl and substituted aryl groups such as anisyl.
  • Alkaryl groups include methylphenyl, dimethylphenyl, etc.
  • Representative examples of aralkyl groups represented by groups include benzyl.
  • Representative alicyclic groups include cyclobutyl, cyclopentyl, and cyclohexyl groups. Examples of an alkynyl group are propynyl and ethynyl, and examples of alkenyl groups include a vinyl group.
  • an infrared sensitive dye borate in at least one set of the microcapsules enable the sensitivities of the microcapsules to be spaced apart to minimize overlap in their sensitivity curves and thereby minimize crosstalk.
  • Infrared sensitive borates can be used in any or all of the cyan, magenta or yellow forming microcapsules.
  • an imaging system can be designed in which the microcapsules are sensitive at 750, 850 and 1050 nm.
  • the red sensitive capsules described in U.S. Patent 4,772,530 (Gottschalk) are replaced with infrared sensitive microcapsules prepared using one of the dyes in the appendix such as the dye #5 in Table 1.
  • an imaging system can be designed in which the microcapsules are sensitive at 800, 900 and 1100 nm.
  • the cyan, magenta and yellow forming microcapsules are sensitive at 450, 550, 650 nm respectively.
  • any of 450, 550, and 650 sensitizers is replaced with an infrared dye.
  • the magenta 550 initiator is replaced with an infrared dye to achieve the most separation in the absorptions.
  • a 450, 840, 650 nm system might be used.
  • the infrared sensitive compositions can be modified to include an autoxidizer such as N,N-dimethylaniline as described in U.S. Patent 4,772,530 which is incorporated herein by reference.
  • an autoxidizer such as N,N-dimethylaniline as described in U.S. Patent 4,772,530 which is incorporated herein by reference.
  • the ultraviolet initiator can be selected from among those that are known in the art. Some examples are provided in U.S. Patent 4,399,209.
  • the infrared sensitive dye is normally used in an amount up to 1 % by weight based on the weight of the photopolymenzable species and more typically in an amount of about 0.2 to 0.5% by weight. However, those skilled in the art will recognize that the amount is easily adjusted to achieve the desired sensitivity and photographic response in the photosensitive material.
