Abstract:
The present invention relates to a method of manufacturing a golf ball having a single cover layer of heterogeneous composition. One embodiment of the invention describes a method wherein a core, comprising one or more layers, has pre-molded hemispherical cover cups placed about the core and each cover cup has at least two layers of distinct resinous materials, and the cover cups are heated and compressed such that the resinous materials in the cover cups intermingle with each other to form a single heterogeneous cover layer.
Abstract:
Multi-layer golf balls having a relatively hard outer core surrounding a relatively soft, low compression inner core are provided. The inner core generally has a compression of less than 50 and the inner core and outer core generally have a combined dual core compression of 50 or greater. The outer core generally has a Shore C hardness of 80 or greater. A cover, which can be a single-, dual-, or multi-layer cover, is provided to surround the outer core. A moisture barrier layer is optionally provided between the outer core and the cover. The moisture vapor transmission rate of the moisture barrier layer is preferably less than the moisture vapor transmission rate of the cover.
Abstract:
Multi-layer golf balls having a hard, high compression center, a relatively soft intermediate layer, and a stiff outer cover layer, are provided. The outer surface hardness of the intermediate layer is less than that of both the center and the outer cover layer.
Abstract:
The present invention is directed a golf ball comprising a core and a cover and an optional intermediate layer disposed between the core and cover, wherein at least one of the core and the intermediate layer comprises any Pantone Matching System color including blue, green, yellow, pink, or orange having an L* value of about 80 or less; and wherein the cover comprises a translucent thermoset polyurethane material and an amount of pigment or dye such that the cover has any Pantone Matching System color including blue, green, yellow, pink, or orange that has an L* value of about 80 or less. The thermoset polyurethane material may be formed from an aliphatic isocyanate-based composition.

Abstract:
The present invention is directed to golf balls consisting of a multi-layer core and a cover. The multi-layer core consists of a center and an outer core layer that are both soft relative to a hard rubber intermediate core layer. The outer core layer is preferably thin relative to the center and the outer core layer. The multi-layer core includes at least one layer formed from a relatively soft HNP composition and at least one layer formed from a relatively hard HNP composition.
Abstract:
Golf balls comprising a multi-layer core and a cover are disclosed. The multi-layer core comprises at least one intermediate core layer formed from a metallic, composite, or inorganic/organic hybrid composition.
Abstract:
Golf ball having at least three layers comprising ionomeric and/or HNP compositions, wherein for each two adjacent layers, a relationship is established between a ratio of the volumes of the two adjacent layers and a ratio of the percent neutralizations of those two layers such that the volumes and % neutralizations of all layers are interrelated and interdependent to produce unique and desirable playing characteristics. In one embodiment, a golf ball of the invention has T layers, wherein T≥3 and each of T layers has a different volume “V” and comprises an ionomeric and/or HNP composition having a different % neutralization “N”. Furthermore, each of n inner layers of the T layers (n
