Claim Text:
1. A printed article comprising a thick clear layer comprised of at least two clear layers that are directly in contact with each other and the at least two clear layers are formed using an ink composition for forming a clear layer, and the thick clear layer is formed at least on a recording layer which is formed on a substrate, wherein the ink composition for forming a clear layer contains a polymerizable compound consisting of polymerizable compound(s) that can be cured by radical polymerization, a photopolymerization initiator and a surface tension regulator, wherein the polymerizable compound comprises a (meth)acrylate monomer as a monofunctional monomer or a polyfunctional monomer, and oligomers or prepolymers, the recording layer is formed of an ink composition containing a coloring material, a polymerizable compound, a photopolymerization initiator and a surface tension regulator, wherein the polymerizable compound comprises a (meth)acrylate monomer as a monofunctional monomer or a polyfunctional monomer, the substrate is selected from the group consisting of polypropylene which have been subjected to corona discharge treatment, polyethylene terephthalate, polycarbonate, polystyrene, polyvinyl chloride, polyvinylidene chloride, and an acrylonitrile-butadiene-styrene copolymer, the surface free energy of the substrate is 30 to 45 (mJ/m the surface free energy of the recording layer is 40 to 50 (mJ/m the contact angle of the ink composition for forming a clear layer to the substrate is 30 to 65 degrees, the contact angle of the ink composition for forming a clear layer to the recording layer is 40 to 55 degrees, and the contact angle of the ink composition for forming a clear layer to the clear layer is 45 to 60 degrees.
