Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to golf balls, and more particularly to golf balls.
Or a golf ball using prepared balata as a cover.

Almost all conventional golf balls have white paint on the surface? Recently, colored balls such as yellow, contrast color, and peach have become popular because they are visible even at dusk and stand out even among the greenery. For color balls, add fluorescent paint or fluorescent pigment to the surface of the cover.
In the case of a balata cover, a balata cover is coated with a vulcanizing agent mixed with rubber, bleeding of vulcanization accelerator blue 11, and a cover with a surface texture to improve the adhesion between the paint and the cover. Due to the yellowing of the surface, the color paint layer on a relatively transparent surface appears cloudy and darkened, and a color ball with the bright tone characteristic of fluorescent color paints cannot be obtained. Also, if there are cuts or scratches on the face caused by turtles or iron clubs during play, or if the white cover is exposed on the surface, the difference in color with the color paint may cause scratches or scratches. There was a drawback that the L@ was very noticeable and caused discomfort to the user.

The present invention was completed as a result of intensive research to solve these problems. A golf pole coated with a base layer of paint containing a pigment with high shading power is colored with the same color as India.

The pigment used may be any organic pigment, inorganic pigment, fluorescent pigment, etc. Examples of pigments that color the skin are L.

Examples include benzidine organic pigments such as Brilliant Scarlet G.

The amount of pigment to be added should be such that it does not deteriorate the physical properties of the cover, and is usually 1 to 10 times larger than the cover material.

A golf ball molded using a colored cover is subjected to the usual pretreatment, then the first layer is coated with a paint containing an inorganic pigment with a high shading power, and then a layer of color paint is coated with a paste. Paint with clear paint and get Souji. The first layer of paint contains our pigment in a solids content of 1 to 90 needles, preferably 10 to 60 needles. Inorganic I-4 is preferably white and has a strong cloud-shielding power, and ψ11 is preferably titanium oxide.Color 1: A flame color that does not give any echoes. 1 for things
In addition, in addition to this pigment, it is also possible to use a k-light pigment of the same color or the same color tone as the color paint, or some color pigment. Further, the coating thickness of this paint is preferably as thin as possible as long as the deprivation power is not impaired, and is preferably about 5-20%.

As a result of applying the same color as the color paint on the base layer, the color paint layer may appear smeared or have cut scratches. This has the effect of making the undercoat stand out more than the paint and making up for any imperfections.

Comparing the results of coating the above golf ball with the paint of the present invention and the paint of the comparative example, the following results were obtained.
