Description
Technical field
The present invention relates to a kind of printing ink, particularly a kind of photocureable magnetic offset lithography printing ink belongs to technical field of ink.
Background technology
Lithography technique and letterpress technology all have long history.The lithography print speed is fast, technology maturation, and print quality is good, but the rate of drying of the printing ink that is complementary with it is unsatisfactory, often has set-off, adhesion accident to take place.The radiation curing product have save the energy, be beneficial to environmental protection, economy and characteristics such as efficient, so be widely used in every field.Along with development of technology, more and more print producer radiation curing technology is combined with the offset lithography technology, thereby reach print speed faster, the time that minimizing printing slow-drying brings and the waste of material.
Traditional magnetic mode that is coated with is coated on the base material by the mode of showering or roller coat usually with solvent type coating or printing ink, through operations such as volatile dry, magnetic orientations, reaches suitable magnetic property.In order to make solvent seasoning, a very long dry road is usually arranged on coating line, this not only causes equipment, the energy and waste of time, and environment and workman's personnel safety also caused serious harm.
U.S. Pat 5,682,670 have described a kind of manufacture method that contains the heat-set ink of magnetic, and this printing ink is imprinted on engine and the electrical condenser by screen printing mode, can access lasting magnetic property after the curing.This patent is used screen printing mode and the thermosetting magnetic ink is imprinted on the pattern of design in advance, this mode is presented at some problems that exist in the printed on line, especially, the additional condition of cure of thermosetting magnetic ink needs that shows in this patent, as 100 ℃, 30～60 minutes, for printed on line, any curable component of curing level needs can both reach dry solidification and be only available within 1 minute.This patent needs coating technique that the printed layers of two different poles (South Pole and the arctic) is combined, to obtain multipole magnet.
U.S. Pat 20040001973 has been described a kind of radiation curing magnetic component, and this component is applicable to figure and the literal that printed on line designs in advance.This component can be printed different zones and shape, can also eliminate the infringement to cutting knife, and therefore reduces the life-span of expending and prolong cutting knife.This radiation curing magnetic component can directly be printed on the non magnetic ground, becomes no attachment magnets after the curing, has lasting magnetic property, can write down customized information, image and direct market information; It mainly uses coating method or screen printing mode, is imprinted on the one side of non magnetic ground, and the another side of ground, printed pattern and literal, printed magnetic component is generally 25～100 microns.
