Description
;. ~2~6~78 GOI,F BALL WIT~I FLUORESCENT COVEP~
The present invention rel~tes to golf balls and, in particular, golf balls having a fluorescent appearance rather ~han the traditional whi~e appearance.
For approximately the last 40-50 years golf balls have been made by bonding a covex about a coreO The cov~r can either be compression molded from two half shell~ or it can be directly injection molded as a fluid a~out ~he core. ~ntil a~out th~, mid 1960's mos~ gol~ - -ball covers were made o~ a natural resin, nota~ly bala~a~-Since the mid 60's a syntheti~ resin sold under the ~rademark IlSurlyni' by Eo I. Dupont has increasingly assumed a grea~er posit;on as a golf ball cover material and it has, today, the major share of the marke~O Covers made o such materials are described in U~S. Pa~ent lS Nos. 3,~54,290 and 3~8~9,281.
Various at~emp~s have been made ovex ~he years ~o make o~e piece solid gol~ ballsO However~ no one has succeeded in making a top grade one piece golf ball~
Top grade go~f ba~ls today axe made with a cover material as mentioned hereinbefore molded a~ou~ a core~ wi~h the core being ei~her a wound core ox a solid core, both o~ which are ver~ well know~ in the artO
No matter what the construction OL the gol~ ball or the composition o~ the cover~ it has been the practic2 in the art to apply a ~inish to the surface o~ the gol~
,. ~ 2~ ~ ~7 ~
ball cover. This is an elabora~e, expensive and highly developed technology. A typical painting operation with a Surlyn eovered golf ball involves sand blasting the surface of the cover9 washing, drying and then the successive steps of applying a primer, drying the primer at about 100F9 applying a first whi~e coat, drying the first coa~ at about 100 F~ applying a second white coat, d~ying ~he second coa~ at about 100F, stamping a ~rademark -2ad ~umbersg and then following with a clear finish coa~
and dr~ing it at about ~00F, Despi~e these many steps, even the best of manufacturers have some wearing away o~
~he paint sur~ace~ especially a~ter ex~ensive use of ~he ballO This is especially true with the Surlyn covered golf balls~
The problem is particularly acute when the cover is a different color from the paint ~yste~ as is the case wi~h both balata and Surlyn covers when they are painted whiteO
Most manufac~urers at~empt ~o compensa~e for ~his colo~
difference by lncluding a white~ing agen~, usual~y titanium 20 dioxide, in ~he cover composi~ion. This impar~s a whi~e appearance to the cover. However, this is quite a dull white appearance and the di~ference bets~7een the surface color and the cover; even where the cover contains titanium o~ide, i is generally quite noticeable to the golfer as the pain~
wears away.
While they have generally f~llen out of favor today, there was a time when red coated golf balls were manu-facturered and sold9 particularly for play by "snow birds"~One of ~he reasons ~hat these were not generally accep~ed, even though they could be very well seen as compared to a ~ite golf ball when played in sno~y or heavy frost con-di~ions~ was that the paint would come off ~airly quickly revealing the white cover~ This caused the balls t~ be associated with poor quality, as a result o~ which sale of them was never very greatO There have also been attempts from time to time to market pastel coated go~f balls as 'tladies balls"~ These have, however, never achieved great success and this is also believed to be a resul~ o~ ~he appearance-durabillty pr~blem~
A~ the present time ~here is a craze sweeping ~he gol~
ball world with respect to golf balls covered with ~luorescent paint~ These golf balls have been found by many t~ be substantially more visible ~han the traditional whi~e golf ballsO While some have predicted that ~hîs craze will go the way of aluminum shafts, ~raphite sha~ts, floating golf balls, steel centers and the like, others predict that fluorescent golf balls will become a permanent and larOe ~.2~ 7~
share of the golf b~ll ma~ket.
One of the circumstances that ma~ prevent these fluorescent colored yolf balls fro,~ becoming a permanent share of the market is the old pro~lem of pain~ wear. As with the sno~,7 bird and ladies golf balls, the fluorescent covered golf balls are having a substantial problem with paint wear and the balls on the market today are showing quite poor appearance-durability~ Not only do the paints wear away to show the cover color, but they also have a substantial tendency to chip off revealing large portions of the cover.
- The applicant has now discovered that the appearance-durability problem of fluorescent covered golf balls can be overcome by incorporating the fluorescent material directly into the cover composition. This is not a simple replacement of the titanium dioxide for white golf balls with a fluorescent coloring agent for fluorescent golf balls. Quite the contrary, the applicant has found that fluorescent material incorporated in the cover of the golf ball can be used as the finished cover of th~ golf ball.
The final surface of the golf ball is clear coated as in the past; however, no opaque coating is app3ied as has been done with gol~ ba31s, including colored golf balls, since the '20's.
According to another aspect of the present invention there is provided a method of making golf balls which includes the steps of forming a solid core, forming a cover composition by admixing a resin and a fluorescent material, molding the cover composition about the solid core, and applying a clear coating to the outside surface of the cover without previously applying any opaque coating thereto.

The present invention is especially advan-.ageous where the golf ball cover ma~eri~l is clear, e.~, most Surlyn resins. While a wound golf ball can be used ~ith a clear cover for "special effects" it is preferred that the co~e be a one-piece solid. It is also pre~erred that the core be essentially white in colorO Where a white core is used wi~h a clear cover~ the stamping can be pu~ direct-ly on the core and can be seen through ~e coverO This i3 true even where a fluoresce~t ma~erial is used to ~olor ~he gol~ ball cover material. Th~s is of ve~y grea~ ad-vantage since it ensures a long lasting and~ indeed~
relatively permanent retention of the trademark and identification number and any other markings put on the ballO This also overcomes o~e o~ the more di~icult prob-lems of high quali~y golf ~all manufacture, poor stamping.
It advantageously permits the use of a low quali~y ~oll f~r the stamping since the foil is not required to have durability charac~eristicsO
While ~he golf ball with the fluorescen~ material 2Q therein is a very good looking golf ball~ the gloss can be made e~en greater by the application o one or more clear~
or essentially clear, top coatsO The top coat should be of suff~ient clarity so that the covered material can be seen therebeneath. If the top coat is opaque, the primary 7~3 advan~ages of ~he present invention canno-~ be oh~ained~
The 1uorescent ma~erials useful in the pr~sent invention are commercially availa~le ~luorescent pigments and dyes. They are describ2d in U.S. Paten~ Nos. 2,809,954,

The 1uorescent ma~erials useful in the pr~sent invention are commercially availa~le ~luorescent pigments and dyes. They are describ2d in U.S. Paten~ Nos. 2,809,954,
2,938,873, 2,851,424 or 3J412,0360 A good commercial source for these products is Day~lo Color Corpora~ionO The ~mount of fluorescen~ material ~o be used is largely a matter o~
choice depending on ~he brigh~ness desired, ~owever, i~
is preferred that the amount of ~luorescent dye ~e from about 0.01% to about 0O407O by weight of the cover compo-sition and the a~ount o~ fluorescent pioment be from a~out 0.5~ to abo~t 6% by weight of the cover compositionO

Where i~ is desired that the trademark and number be put on the surface of the golf ball cover rather than on the core, a fluorescent pigment can be used rather than a fluorescent dye. This will give a translucent fluorescent cover. ~lowever, as in the situation where the fluorescent dye is used, no opaque finish is applied to the surface of the golf ball; if any coating is used, it is an essentially clear coating.
It is also possible to obtain special effects by adding other coloring materials. For example, a white opacifying agent such as titanium dioxide or calcium carbonate can be used to make the cover essentially opaque. This can be used to hide the threads of a wound golf ball. Again in this case, howe~er, it is preferred that any coating be limited to a clear coating.
These and other advantages of the present invention may be understood from the ~ollowing examples:
`
A solid core was used for the golf ball. The solid core was white in appearance and was the core from the commercially available PINNACLE golf ball. The cover composition was prepared by admixing 99.96% by weight Surlyn and 0.04% by weight Dayglo Fluorescent Dye Saturn Yellow.
The cover composition was formed into gol~ ball mab/ ~
¦ half shells in the s~and~d m~nner in an inj~ctlon molding machine. At ~e same tim~, the gulf b~ll core was stamped wlth a trademark and a number. Thereafter the golf ball hal~ shells were compression molded about the core. Tne flash line from the compression molding was removed by bufing, It was noted that substantially less care was required in ~he buffing operation than that usually required with titanium dloxi~e p~gmented golf ball covers, The buffed golf ball was then clear coated in the standard manner, The result~ng golf ball had a very pleasing fluorescent appearance with a high degree of gloss. The trademark was clearly visible through the cover, In extended hitting tests, the golf ball was found to have substantially better appearance-durability than commercially available fluores-cent colored golf ballsO At the end of 200 hits equivalent to 200 yard drives, the appearance was almost the same as the initial appearance and the trademark was still fully ~ intact and clearly visible.
ij 20 rEXAMPLE 2 Example 1 is repeated with the sam2 cover composition on a wound coreO In this case, however, the trademark is applied to the surface of the golf ball cover before the clear coat is applied~ A golf ball with the windings ~5 visible is obtained.

E~MPLE 3 Ex~mple 1 is again repea~ed except tha~ in this case a clear coat is not employed~ A comparable golf ball but with somewhat less gloss is o~tained.
Example 1 is repeaked except that in ~he place of the Dayglo Sa~ur~ Yellow, the Lemon Yellow rom the Lawter Chemical Co. of Skokie, Illinois is used~ Com parable results are obtainedD
Example 1 is repeated excep~ that ~he amountof Dayglo Saturn Yellow is increased to 0~40%O A compara~le golIC ball is obtained but the high level of dye makes the ball somewhat less bright and so less visible, Example 1 is repea~ed except that the amoun~ o Dayglo Saturn Yellow is reduced ~o 0~01%o A comparable golf ball is obtained excep~ tha~ it does not have the fullness of the color of th~ golf ball of Example 1.
EXAMP~E 7 ~ xample 1 is repeated except that a fluorescent p;gment is used rather than a 1uorescent dye and the trademaric is applied to the surface of the golf ball cover before the clear coat is applied. The ~luorescent pigmenk is Dayglo Saturn Yellow A-17-N and is used in the amount of 2~0% by weight. The resulting golf bal1 has a vPxy pleasing fluorescent appearance but without the clear cover of the gsl~ ball o~ Example 1. A ~rans-lucent cover is ob~alned~
