A single phase aqueous curable composition suitable for thermal inkjet printing comprises a mixture of curable materials, water in amounts in the range 10 to 30% of the weight of the compositions, and one or more co-solvents for the curable materials. Because the water content is relatively low, a drying step is not required before curing, increasing printing speeds. The composition has good performance and has good adhesion to a wide range of substrates including non-porous and semi-porous materials as well as porous materials.

The present invention relates to a printing ink composition containing a colorant, resin and solvent, where the resin is a polymerized fatty acid-based polyamide resin and the solvent is made up of at least one first solvent and at least one second solvent, as well as methods of making and using the same.

The invention relates to a double-color mould molding device for a tape and a molding method thereof. A double-color plastic technology is used for replacing marks and decorations such as labels, and the like on the traditional tapes, and different characters or numbers or patterns i.e. different convex and concave surfaces can be designed so as to be beneficial to the identification of users. The molding device mainly comprises a male mould fixing seat, a first male mould, a second male mould, a female mould fixing seat, a first female mould, a second female mould, a central rotating shaft and a middle plate, wherein both the first male mould and the second male mould are connected with the middle plate and can rotate and arrange the first male mould above an insert fixing seat of the second male mound and rotate and arrange the second male mould above an insert fixing seat of the first male mould through the central rotating shaft connected with the middle plate, thus the double-color mould can finish double-color glue injection under the condition of not changing the mould molding device.

The invention is directed to a method of making a golf ball comprising the steps of: providing a core comprising at least one layer; forming a cover about the core comprising at least one cover layer comprising a cover inner surface and a cover outer surface and having a thickness D; treating the cover outer surface with a fatty acid and / or fatty acid salt composition and forming a treated cover region which extends inward from the cover outer surface a penetration depth DCTr, an untreated cover region being disposed between the cover inner surface and the treated cover region and having a depth (DCUTr)=(D)−(DCTr); wherein the treated cover region has a hardness α and the untreated cover region has a hardness β different than the hardness α. In another embodiment, the method may alternatively comprise the step of treating the cover inner surface with a fatty acid and / or fatty acid salt composition and forming a treated cover region which extends inward from the cover outer surface a penetration depth DCTr, an untreated cover region being disposed between the cover inner surface and the treated cover region and having a depth (DCUTr)=(D)−(DCTr); wherein the treated cover region has a hardness α and the untreated cover region has a hardness β different than the hardness α. In yet another embodiment, the method of making the golf ball comprises the steps of providing a core comprising at least one layer; forming a cover about the core comprising at least one cover layer comprising a cover inner surface having a hardness β and a cover outer surface having a hardness α; treating the cover outer surface with a fatty acid and / or fatty acid salt composition and forming a treated cover outer surface comprising the fatty acid and / or fatty acid salt composition wherein the treated cover outer surface has a hardness α′ different from hardness α; and wherein hardness β is different than at least one of hardness α and hardness α′.
