Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
110 words
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.
Claim 2
Dependent Claim
110 words
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.
Claim 3
Dependent Claim
35 words
A process according to claim 1, wherein the front side of substrate coated with a radiation curable coating media is contacted with a back side of succeeding portion of the substrate at the laminated portion.
Claim 4
Dependent Claim
47 words
A process according to claim 1, wherein the front side of substrate coated with a radiation curable coating media is contacted with a back side of preceding portion of the substrate having mostly cured coating media on the front side of the substrate at the laminated portion.
Claim 5
Dependent Claim
16 words
A process according to claim 1, wherein the radiation is an ionizable radiation or ultraviolet rays.
Claim 6
Dependent Claim
105 words
A process for producing an adhesive tape 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, curing the coating media by irradiating a radiation at the laminated portion, and wind up the support having the radiation cured coating thereon on a reel.
