The present invention relates to a paint composition for a logo. The paint composition comprises: two to five parts by weight of a radical optical initiator; two to five parts by weight of a positive ion optical initiator; 20 to 30 parts by weight of a 6 functional urethane acrylate oligomer; 20 to 30 parts by weight of cycloaliphatic epoxide; and 10 to 20 parts by weight of hexanediol diacrylate. In addition, the present invention relates to a coating method using the paint composition for the logo, which comprises: a step A of manufacturing a paint composition for a logo using a 6 urethane acrylate oligomer and cycloaliphatic epoxide; a step B of coating the paint composition for the log on a top film; and a step C of hardening a coating layer coated in the step B by a UV hardening apparatus. In the step C, the coating layer is hardened by the light quantity of 500 to 1000 mJ. Therefore, energy is saved and productivity is excellent because an adhesive property, hardness, and solvent resistance are excellent by realizing the paint composition for the log of an UV hardening system type instead of a 2K solvent type and the paint composition is directly dried by using the UV hardening system. In addition, a residual paint composition is not existed on a dried film after the UV hardening because a solvent is not used so that the paint composition is eco-friendly. |
