Golf ball with moisture exposure indicator

Abstract

A golf ball is provided which changes color or other indicia after exposure to moisture to indicate that the ball may not have predictable flight characteristics which may result in loss of carry and roll. In one embodiment, a microencapsulated dye layer is formed immediately below the final gloss coat, with controlled dye release causing a stained look to the ball after significant exposure to moisture. In another embodiment, the dye or ink is provided in pelletized form for ease of manufacture. In other embodiments, a dye, ink, or chemical is compounded with other materials and introduced into or applied onto the golf balls composite materials in a solid, liquid, or gaseous form. In still other embodiments imprints on the ball are made with a water activated ink which either appears or disappears upon the exposure of the golf ball to moisture.

1 . A moisture exposure indicating golf ball which changes appearance upon exposure to moisture to indicate that otherwise invisible characteristics of said golf ball have been altered due to said exposure, comprising: 
 materials providing said golf ball with predetermined characteristics of play including weight, size, spherical symmetry, overall distance, initial velocity, and other flight characteristics conforming to golf ball characteristic standards; and,    imprints on said golf ball made with a water activated marking material which changes appearance to indicate that the performance characteristics of said ball have been altered due to said exposure, whereby otherwise playable golf balls retrieved from water hazards can be identified as having altered performance characteristics due to said exposure.    
   
   
       2 . The moisture exposure indicating golf ball of  claim 1  wherein said water activated marking material is a transparent marking material that appears upon exposure to moisture.  
   
   
       3 . The moisture exposure indicating golf ball of  claim 1  wherein said water activated marking material is a vanishing marking material that disappears upon exposure to moisture.  
   
   
       4 . A golf ball, comprising: 
 one or more layers of construction, and    imprints on said golf ball made with a water activated marking material which changes appearance upon the exposure to moisture.    
   
   
       5 . The golf ball of  claim 4  wherein said water activated marking material is a transparent marking material that appears upon exposure to moisture.  
   
   
       6 . The golf ball of  claim 4  wherein said water activated marking material is a vanishing marking material that disappears upon exposure to moisture.  
   
   
       7 . A golf ball comprising: 
 materials providing said golf ball with predetermined characteristics of play including weight, size, spherical symmetry, overall distance, initial velocity, and other flight characteristics conforming to golf ball characteristic standards; and,    imprints on said golf ball made with a water activated marking material which changes appearance to indicate that the performance characteristics of said ball have been altered, whereby otherwise playable golf balls can be identified as having altered performance characteristics due to the occurrence of an event.    
   
   
       8 . The golf ball of  claim 7  wherein said water activated marking material is a transparent marking material that appears upon the occurrence of an event.  
   
   
       9 . The golf ball of  claim 7  wherein said water activated marking material is a vanishing marking material that disappears upon the occurrence of an event.
