Method for marking golf ball and golf ball

Abstract

The invention provides a golf ball marking method of marking the surface of a golf ball with a character, pattern or the like by a direct or indirect printing technique, comprising applying a marking layer onto the ball surface for marking, the marking layer being of a two-layer structure consisting of a lower layer of a composition containing a color pigment in a lower layer ink medium and an upper layer which is formed on the lower layer from a composition containing a metal powder in an upper layer ink medium and which is transparent or translucent and has brilliance, and adjusting the content of the metal powder and the thickness of the upper layer such that the relation of the content (wt %) of the metal powder relative to the upper layer ink medium solids to the thickness (μm) of the upper layer may satisfy the inequality: 1≦[metal powder content (wt %)]×[upper layer thickness (μm)]≦10. When it is desired to impart brilliance in a dark color such as black, the dark color is improved in sharpness and reproducibility.
