Transfer printing film and golf ball marked by the same

The invention provides a transfer printing film for thermally printing patterns on golf balls. An ink layer disposed on one side of a substrate film contains as a main vehicle a polyamide bearing methoxymethyl group or a vinylchloride-vinylacetate-vinylalcohol copolymer bearing hydroxyl group. Softening point of the polyamide or the copolymer is relatively low, and thus, the pattern formed by the ink layer is transfered at a lower temperature. Both the methoxymethyl group of the polyamide and the hydroxyl group of the copolymer reacts with isocyanate group to form urethane bond, and thus, in the operation of finishing the golf ball with a two-component urethane paint, urethane bondings are formed between the urethane clear top coat and the printed pattern.
