Publication number: 20020010226Abstract: Light cured nail coatings that are applied to natural nails and/or artificial nail-tips for cosmetic purposes. An optional bond-enhancing compound can be used to strengthen the bond between the light curable coatings and the natural nail. Also, finishing compounds may be used to clean the surface of the uv curable coatings resulting in a high-gloss shine. The methods of applying uv-radiation curable nail coatings, bond-enhancing compounds, and finishing compounds to artificial nail-tips and natural nail are also discussed.Type: ApplicationFiled: July 24, 2001Publication date: January 24, 2002Inventor: Pamela H. Lilley

Patent number: 6248804Abstract: Radiation curing of inks on game balls, golf balls and the like is disclosed. The radiation used is ultraviolet and/or visible light. Production inks, logo inks and methods for forming production prints and logos on golf balls, game balls and the like are disclosed. To ensure that the ink is sufficiently through-cured, visible light photoinitiators are added to the ink. In addition, co-initiators and ultraviolet light photoinitiators can also be included in the ink. To form a radiation curable water-insoluble production ink, at least an adhesion promoting component is added to an ink base. The adhesion promoting component is sufficient to maintain adhesion of the production ink of at least about 75% of the inked surface to the topcoat and to the surface of the game ball or the golf ball after radiation curing and after coating the production ink with the topcoat. To form radiation curable water-insoluble logo ink, at least a toughening agent is added to an ink base.Type: GrantFiled: January 20, 1998Date of Patent: June 19, 2001Assignee: Acushnet CompanyInventor: Mitchell E. Lutz
