The present invention relates to a golf ball coated with a coating composition on the surface of the golf club hitting the golf ball with the trace material on the hitting point of the club head.

Today, golf is becoming one of the most popular sports enjoyed by many people around the world including Korea. Like most sports, golf also differs in accuracy and skill, depending on the individual's natural ability and level of effort. In particular, whether or not the golf ball is hit at the golf head hit surface at the time of impact contact with the golf ball during the swing operation from the address to the finish is a very important factor for accurate swing.

Conventional methods for determining whether a golf ball is properly hit on a hitting surface include the following. Republic of Korea Utility Model No. 20-0319802 attaches a label consisting of Thermal Sensitive Paper or Pressure Sensitive Paper to the face of the golf club head, and the RBI marked on the thermal paper or pressure-sensitive paper label after the swing practice. We propose a technique to check, but when removing the RBI sheet, the RBI sheet can't be separated cleanly, the parts are torn off, or the remaining adhesive foreign matter gets stuck on the face. There was pain and discomfort.

Republic of Korea Utility Model No. 20-0311966 is devised to add the attachment means to the hitting surface of the golf club head and one surface of the golf ball to hit the golf ball and at the same time the hitting surface of the head and the golf ball is attached to check the RBI. Although it has been proposed, there is a problem in that the sponge is placed on the golf ball in order to attach the golf ball can not feel the real blow.

Korean Utility Model Publication No. 1999-0033822 proposes a method in which an ink container is embedded in a golf ball so that a certain amount of pigment, etc., leaves a trace whenever a blow is applied, but the device is complicated and can withstand a strong blow. The problem is that it is difficult to have a durable, and difficult to manufacture to feel the real blow.

The present inventors have tried to solve the problems of the prior art as described above, by applying a coating composition on the surface of the golf ball, it can be traced to the trace point of the club head when hitting the golf ball with the golf club. Discovered and completed the present invention.

Accordingly, an object of the present invention is to provide a golf ball coated with a coating composition on the surface of the golf club or the game so that the spot can be immediately identified from the head face of the golf club while maintaining the actual feeling of impact.

The present invention relates to a golf ball is coated on the surface of the coating composition so that the trace material is buried in the hitting point of the club head when hitting the golf ball with the golf club.
