Description
According to 119 regulations of 35U.S.C. ξ, the present invention requires the temporary patent application sequence number No.60/075 to submit on February 25th, 1998, and 892 as basis for priority.
The application is a kind of improvement to the imaging system of describing in the United States Patent (USP) 4,399,209,4,440,846 and 4,772,530 of Cycolor company.These imaging systems adopt one deck photosensitive microcapsules.And microcapsules are to make by containing to handle through microencapsulation to the composition of the free redical polymerization of electronic color precursor.Usually, imaging system shows as two kinds of forms.One, imaging system are transfer printing systems, in this individual system, the supporter that has one deck photosensitive microcapsules is accepted radiation with image mode (image-wise), and be combined on the developer thin slice, for example, the developer thin slice can contain the lewis acid of one deck such as phenolic acid resin and so on.This assembly makes microcapsules rupture under pressure, microcapsules are revealed the material wherein sealed to the developer thin slice with image mode, make the colour developing of color precursor.In another kind of form, imaging system be one self can imaging system, wherein light-sensitive microcapsule and lewis acid are in the surperficial last layer of a same matrix or in the adjacent layer.In U.S. Patent Application Serial Number the 08/570th, 658 and the International Patent Application WO 95/34845 announced in the further embodiment of imaging system is disclosed, contain light-sensitive microcapsule layer and developer layer and be sandwiched between two plastic foils, wherein at least one film is transparent.Use the combination of adhesive and glue-line, thereby these films are sealed permanently a kind of film unit are provided.This structure is highly beneficial, because it has prevented that the chemical reagent in the imaging system from contacting with the user.
Preferably a kind of full-color imaging system of this imaging system is wherein used the combination of three kinds of different microcapsules, and every kind of microcapsules are only to specific wave band sensitivity.This full-color imaging system was described for 976 li at United States Patent (USP) 4,842.According to a commercial explicit declaration of this imaging system, three kinds of microcapsules contain blueness, magenta and yellow color precursor respectively, and they are respectively to the red, green and blue photaesthesia.What in another embodiment, the United States Patent (USP) 4,772,530 of use Gottschalk was described is called as " dyestuff-borate photoinitiator " with these microcapsules sensitizations.In one embodiment, these light triggers are cationic cyanine dyes and such as the anionic complex of triphenyl butyl borine.For photographic copying and other application of using visible light source, imaging system adopts wishes microcapsules red, blue, green light sensitive, and still one of difficulty that is run into is to harass mutually between them when the imaging system that designs the red, green, blue photaesthesia.The absorption spectrum that is red and/or green and/or blue-light initiator can overlap.In this case, be very important in the microcapsules light quantity of exposure latitude built in the overlay region.Otherwise the chromaticness of duplicating will be bad.Prior art discloses the serial of methods that alleviates this problem.Yet along with the development of digital imaging system, the photosensitivity to red, green, blue in many application has just no longer needed.Particularly, printer can be designed to adopt the light source that is in outside the visible wavelength, as region of ultra-red.This give to solve light harass the problem of bringing provide a kind of may because from then on no longer need to limit photochromics in the photosensitivity of visible region, its imaging photosensitivity can extend to the infrared spectrum zone, also can extend to the ultraviolet spectrum district on the other hand.
According to the present invention, aforesaid imaging system, particularly United States Patent (USP) 4,772,530 related imaging systems are enhanced and become to comprise one or more IR-sensitive composition, particularly comprise the dyestuff that one or more light triggers wherein are a kind of infrared-sensitives and the photo-sensitive composition of the anionic complex of foregoing borine.
Correspondingly, a kind of embodiment of the present invention is an imaging system, it comprises supporter, has at least a light-sensitive microcapsule layer on this supporting body surface, and described microcapsules are to the radiosensitive of specific bands of a spectrum and contain the dye of positive ion and the anionic complex of borine of infrared-sensitive.
In another embodiment, this imaging system comprises blue, the pinkish red and yellow capsule of formation, and at least a capsule comprises that the dyestuff borate compound of infrared-sensitive is as light trigger.Randomly, at least a other capsule comprises the dyestuff borate compound or the ultraviolet initiator of visible light sensitivity.
In another embodiment, three kinds of all microcapsules all contain the photo-hardening composition, and said composition contains outer sensitive dye of cationic red and the anionic complex of borine.
Can be used for infrared-sensitive light trigger in the imaging system of the present invention at Japanese Laid-Open Patent Application 3-221506; 4-261405; 8-100011; Describe among 8-100012 and the 8-34808.These disclosures are all incorporated this paper by reference into and are used to the method describing the dye of positive ion and prepare light trigger.The infrared-sensitive dye of positive ion of being mentioned in aforementioned patent is listed in the following table 1, and wherein " Ph " represents phenyl.
