Abstract:
A method of producing a golf ball comprising the steps of:applying an adhesion enhancing agent containing a silyl component and a solvent to a surface of a ball body; drying the coated surface to form an adhesion enhancing layer having the silyl component; and applying a paint to the adhesion enhancing layer; wherein the silyl component is capable of remaining 30 percent or more after an elapse of one hour at a temperature of 25Â° C., and wherein the silyl component includes at least 50% by weight, of a silyl component (P) with respect to a total weight of the silyl component, the silyl component (P) is represented by the following formula (1) and has a weight-average molecular weight of 300 or higher: wherein R1 and R2 are the same or different and each represents a saturated alkyl group having 1 to 3 carbon atoms; X and Y each represents an organic group having an amino group, an imino group or an epoxy group in a molecule; â€œaâ€  and â€œcâ€  are integers of 2 or 3 and â€œbâ€  and â€œdâ€  are integers of 0 or 1, with a proviso that a, b, c and d satisfy the following relations: a+b=3 and c+d=3; and â€œAâ€  is a divalent residue containing at least one selected from an amide group, an oxy group, an imino group, a tertiary amino group and an alkylene group.
