Provided is a resin composition for an under coat of an UV coating layer and a coated steel sheet using the resin composition. The coated steel sheet comprises a material steel sheet; an under coat layer including a cured product of a resin composition for the under coat layer which contains a main resin and a metal powder, the under coat layer being formed on one side or both sides of the material steel sheet; and a top coat layer formed on the under coat layer and containing a radical compound, thereby providing a superior appearance, scratch resistance, corrosion resistance and superior weldability.

Coated steel sheet having superior welding, scratch-resistance, and corrosion-resistance properties

A radiation-curable base resin composition and a fingerprint-resistant resin composition including the same are provided. The radiation-curable base resin composition includes a multifunctional urethane(meth)acrylate having three or more functional groups at 3 to 35 parts by weight, a bifunctional urethane(meth)acrylate at 3 to 35 parts by weight, at least one (meth)acrylic acid ester monomer selected from a monofunctional (meth)acrylic acid ester monomer and a multifunctional (meth)acrylic acid ester monomer at 20 to 60 parts by weight and a radiation polymerization initiator at 0.1 to 15 parts by weight.

Radiation curable resin composition, and fingerprint-resistant resin composition containing same

An ultraviolet (UV) curable resin composition is provided which includes 25 to 45 parts by weight of a modified epoxy acrylate oligomer; and 10 to 25 parts by weight of a urethane acrylate oligomer. Further provided is a metal sheet that is transparent and corrosion resistant, impact resistant, scratch resistant, adhesive, anti-corrosive, and bendable (workable) by forming a coating film on the surface of a metal material such as a steel material, specifically a steel sheet, using the UV curable resin composition mentioned above.
