Abstract: Provided as ink for a golf ball for use in marking a golf ball is ink for a golf ball including an ink resin having a predetermined hydroxyl value and block isocyanate. When marking a golf ball by using the ink of the present invention, a hydroxyl group in the ink resin in an ink layer and an isocyanate group derived from the block isocyanate react with each other to increase hardness of the ink layer, thereby improving abrasion resistance of the marking. In addition, the isocyanate group derived from the block isocyanate and a functional group of an ionomer resin on the ball surface react with each other to improve adhesiveness of marking to the ball surface. Furthermore, the hydroxyl group of the ink resin and an isocyanate group in a urethane top coat layer react with each other to increase strength of the ink layer, thereby improving hitting resistance of the marking.

Abstract: A food material nutritionally enriched in mineral composition and improved in taste includes beans or Mugi-rui enriched in magnesium, or magnesium and sodium. The Mg/K chemical equivalent ratio (a ratio of chemical equivalent of magnesium with respect to chemical equivalent of potassium) of the beans falls within the range of 0.4 to 2.0, and Mg/K chemical equivalent ratio of the Mugi-rui falls within the range of 0.8 to 3.0. The food material is manufactured by immersing the beans or Mugi-rui in aqueous solution containing magnesium chloride, or magnesium chloride and sodium chloride, at a certain concentration for a certain period of time.

Abstract: A golf ball having a mark with a distinct appearance unrealizable by only changing in tint. Ink can be prepared by mixing one or more components which provide luster such as pearl particles, shell particles, mica particles and the like in an ink medium. Therefore, ink can be used for marking the surface of the golf ball by an indirect printing used with a transfer printing film or a direct printing such as a pad printing, a screen printing and the like. The composition of the ink is 5 to 150 parts by weight of the mica, pearl particles and the like. The mica, the pearl particles and the like are employed for flat forms.

Abstract: A golf ball is provided which bears a mark having a distinct metallic lustered appearance, being superior in durability. The mark is printed by using a transfer printing film having an ink layer containing a pigment and metal particles. An ink composition, defining the ink layer, contains 20 to 35 parts by weight of a metal dispersion relative to 1 to 5 parts by weight of a pigment. The metal particle is in a flattened form and a content of the particles in the dispersion is 5 to 15%. An average thickness of the flattened metal particles is 50 to 500 angstroms and an average diameter 10 to 60 microns. Aluminum, chromium, cobalt, steel, silver, gold or nickel alloy are employed as the metal of the particle.

Abstract: A golf ball is provided which bears a mark having a distinct appearance unrealizable by only changing in tint. Ink can be prepared by mixing one or more than two components which can afford luster such as pearl particles, shell particles, mica particles and the like in an ink medium. Thereafter the ink can be used for marking the surface of the golf ball by an indirect printing used with a transfer printing film or a direct printing such as a pad printing, a screen printing and the like. The composition of the ink is 5 to 150 parts by weight of the mica, pearl particles and the like. The mica, the pearl particles and the like are employed for flat forms.

Abstract: The invention provides a transfer printing film, an ink layer of which comprises a urethane resin having a predetermined hydroxyl value and a polyester resin and/or an epoxy resin having an another predetermined hydroxyl value, and provides a golf ball marked by the film. The hydroxyl-functional urethane resin and polyester resin and/or epoxy resin in the ink layer react with isocyanate functional resins in the urethane clear top coat of a golf ball to form urethane bondings respectively, whereby the strong adhesion between the urethane clear top coat and the ink layer is realised, and the transferred pattern becomes to be hardly removed from the golf ball surface and to be superior in hitting durability.

Abstract: A coating composition comprising a two-part curable urethane paint consisting essentially of a polyol and a polyisocyanate, a metal chelating agent having a boiling point of up to 200° C., and an organometallic compound as a curing catalyst is easy to apply to golf balls because of a long pot life and a short curing time.

Abstract: A coating composition for a golf ball which comprises a non-yellowing polyisocyanate and a hydroxyl group-containing polyester obtained by reacting a polyhydric alcohol, at least a part of which has an alicyclic structure in the molecule, with a polybasic acid component, and a golf ball whose body is coated with the above coating composition. When said coating composition is used, a high durability is achieved even when a white enamel coating is omitted from the lower layer part of the coating and the coating step can be shortened.

Abstract: Prior to paint coating, a golf ball is surface treated with a surface treating agent comprising a silane coupling agent of the formula: (RO).sub.a --Si--(X).sub.b wherein R is alkyl, X is a monovalent hydrocarbon group, letters a and b are integers of 1 to 3, satisfying a+b=4 and optionally an epoxy compound. The surface treatment helps the ball surface bear a paint coating of quality. The surface treating agent may be a mixture of the salane coupling agents.

Abstract: A transfer foil for use in marking a golf ball has an ink layer on a base film. The ink layer is constructed by a urethane resin having a hydroxyl value of 0.2 to 15. The ink layer is transferred from the foil to the golf ball to form a marking by pressing the foil against the ball by means of a flat rubber pad. A two-part urethane resin composition is then spray coated onto the golf ball so as to cover the marking, dried and cured thereto. During the process, hydroxyl groups of the ink layer urethane resin react with isocyanate groups available from the urethane resin coating composition whereby the marking is durable.
