摘要:
Disclosed is a phase change ink comprising a colorant, an initiator, and an ink vehicle, said ink vehicle comprising (a) at least one radically curable monomer compound, and (b) a compound of the formula wherein R1 is an alkylene, arylalkylene, or alkylarylene group, R2 and R2′ each, independently of the other, are alkylene, arylene, arylalkylene, or alkylarylene groups, R3 and R3′ each, independently of the other, are either (a) photoinitiating groups, or (b) groups which are alkyl, aryl, arylalkyl, or alkylaryl groups, provided that at least one of R3 and R3′ is a photoinitiating group, and X and X′ each, independently of the other, is an oxygen atom or a group of the formula —NR4—, wherein R4 is a hydrogen atom, an alkyl group, an aryl group, an arylalkyl group, or an alkylaryl group.
摘要:
An ink set is made up of at least three differently colored phase change inks, for example cyan, magenta and yellow, wherein at least one of the colored phase change inks is a photochromic ink that contains a photochromic material. Upon exposure to activating radiation such as ultraviolet light, the at least one photochromic ink changes to a color different from the color of the photochromic ink prior to exposure to the activating radiation.

Disclosed is a process for preparing a compound of the formula wherein R1 is an alkyl group having at least one ethylenic unsaturation, an arylalkyl group having at least one ethylenic unsaturation, or an alkylaryl group having at least one ethylenic unsaturation, R2 and R3 each, independently of the others, are alkylene groups, arylene groups, arylalkylene groups, or alkylarylene groups, R4 and R5 each, independently of the other, is a hydrogen atom or an alkyl group, and n is an integer representing the number of repeat amide units and is at least 1, said process comprising: (a) reacting a diacid of the formula HOOC—R2—COOH with a diamine of the formula in the presence of a catalyst, a solvent, and a coupling agent to form an oligoamide intermediate; and (b) reacting the oligoamide intermediate with an alcohol of the formula R1—OHto form the product.
摘要:
An ink used preferably in jet ink devices includes an ink vehicle, the ink vehicle being made up either (a) a first component curable by a first polymerization route and an associated photointiator, and a second component curable by a second polymerization route and as associated photoinitiator, wherein the second polymerization route is different from the first polymerization route, or (b) a component curable by a single polymerization route with a first and a second photoinitiator system in which the first system responds to longer wavelengths. An image may be formed by such inks by jetting onto a transfer member surface, curing the first component or partially curing the single component while upon the transfer member surface, transferring the ink to an image receiving surface, and completing curing. The first component is preferably curable via cationic polymerization and the second component is preferably curable via free radical polymerization.
摘要:
Curable monomer that is liquid at 25° C., curable wax and colorant together from a radiation curable ink. This ink may be used to form images by providing the radiation curable ink at a first temperature; applying the radiation curable ink to the substrate to form an image, the substrate being at a second temperature, which is below the first temperature; and exposing the radiation curable ink to radiation to cure the ink.
