Abstract
A radiation curable coating media can be cured without using a laminating material prepared otherwise by running a continuous belt-like supporter so as to contact a back side of a portion of the substrate with a front side of a portion of the substrate coated with a coating media to form a laminated portion, wherein curing of the coating media is conducted by irradiation with a radiation in the absence of oxygen.
Claims7
A process for curing a radiation curable coating media which comprises
- running a continuous belt-like substrate so as to contact a back side of a portion of the substrate with a front side of a portion of the substrate to form a laminated portion,
- coating a radiation curable coating media on the front side of the substrate,
- contacting the coating media coated side with the back side of the substrate at the laminated portion to exclude oxygen from the laminated portion,
- irradiating the coated coating media with a radiation to conduct corsslinking at the laminated portion, and
- wind up the support having the radiation cured coating thereon on a reel.
