Estimating the term…
The present invention comprises a radiation curable composition for in-line printing containing magnetic pigments capable of being magnetized to possess permanent magnetic properties after the composition is cured. The composition is cured by an ionizing radiation source, preferably by UV light or electron beam radiation (UV/EB). The present invention is also directed to an in-line process for printing magnetic images on non-magnetic substrate, comprising: pattern applying the above mentioned radiation curable composition on the substrate opposite to a print side, pre-aligning the magnetic pigment particles (if necessary) of the applied composition, curing the composition by ionizing radiation source (UV/EB), magnetizing the cured composition, then finishing the final piece. The finishing step could involve delivering the final piece in a simple sheet with die cut magnets or creating an “integrated magnet” format involving plow folding over the magnet panel, pattern coating or flood coating an adhesive that will only adhere the non-magnet matrix areas between die cut magnets, thus, allowing for the individual magnets to be “popped” out of the carrier by the final end user. The resulting magnetized pieces will possess holding power like magnets (refrigerator and office magnets) and are capable of carrying personalized, Scitex imaged and direct marketing information (including redemption value for coupons, local public service access numbers, etc.)
A radiation curable magnetic composition suitable for in-line printing comprising from 50 to 95 weight % of magnetic particles having an average particle size ranging from 1 micron (μ) to 200μ, in combination with 50 to 5 weight % of a radiation curable resin, said radiation curable magnetic composition having a viscosity within the range of 50 cps to 10,000 cps.
A method for selectively applying a magnetic surface to a non- magnetic substrate, comprising:
A method for making an adhesive-free laminated product suitable for adhering by magnetic attraction to an iron based surface, comprising:
A composite object comprising a non-magnetic substrate having at least one surface to which is directly adhered a layer of a radiation cured magnetic resin comprising 50 to 95 weight % of magnetic particles having an average size within the range of 1μ to 200μ, dispersed within 50 to 5 weight % of a radiation cured resin.
