The present invention relates to a resin composition comprising 40% to 50% by weight of a polyester resin on the basis of a total of 100% by weight of the composition, the polyester resin comprising a main resin and an auxiliary resin, wherein the main resin has a higher molecular weight than the auxiliary resin, and the difference of a glass transition temperature between the main resin and the auxiliary resin is 25&#xb0; C. or less.

Resin composition, black resin coated steel sheet using same, and method of preparing same

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.
