  • Publication number: 20150119238
    Abstract: A method for marking an item including a shape memory polymer (SMP) having a visual readable and/or machine readable graphic element on the surface of the item. The method includes pretreating the surface of the item; colouring the surface of the item with a dye solution containing an organic dye and an organic solvent; cleaning and drying the surface of the item; and engraving by at least partially ablating the surface of the item. The dyeing process is suitable for colouring the surface of a shape memory polymer (SMP), wherein the information is engraved in a form of a code or other label on the coloured surface. The colouring causes an increased contrast and thus facilitates machine readability of marking and coding without affecting the other properties of the SMP.

The thermochromic golf ball reversibly changes between two different color states with temperature. The thermochromic golf ball may be white when it is warmed to higher than a thermochromic temperature point, but shows a characteristic color when it is cooled to lower than the point. In a two-piece or three-piece ball, the thermochromic compound is present in either the outer cover or a transparent coat applied to the cover. The thermochromic pigment changes color when a critical point temperature is reached, thereby alerting the golfer that the current temperature of the golf ball may have power performance characteristics.

  • Patent number: 7189265
    Abstract: A composition of certain dyes with a category-2 hair bleach can simultaneously lighten hair up to seven levels and deposit various shades of color in a single step. The dyes are bleach-stable derivatives of azo, triarylmethane, thiazine, or nitro dyes. When linked at the ortho- and/or para-positions relative to the chromophoric centers and auxochrome groups located on or attached to the aromatic rings of these dyes, deactivating or weakly activating chemical groups enhance the dye stability in the alkaline bleach. The absence of ortho and/or para positioned deactivating or weakly-activating substituents, or the presence of strongly activating groups in these positions render the dye molecule susceptible to attack by the bleach and the eventual destruction of these dyes. These deactivating and protective chemical groups may be nitro, halogen, cyano, carboxyl, sulfonic, alkyl or aromatic groups, but not amino, hydroxy, alkoxy or alkylamide groups.

  • Patent number: 6916348
    Abstract: Tanned leather is (a) pretreated in an aqueous and alkaline medium either with ammonia, primary amines or a mixture of ammonia and primary amines and then with a polyfunctional organic compound containing at least one aldehyde group as a functional group, or (b) in an aqueous and acidic medium with a polyfunctional organic compound and then ammonia, primary amines or a mixture of ammonia and primary amines, and (c) then dyed in an aqueous and alkaline medium with a water-soluble dye containing at least one functional group which is capable of reacting with one of the functional groups of the organic compound, forming a covalent bond. A tanned and dyed leather is obtainable with a high color intensity, outstanding wet fastness and excellent grain tightness, wherein the dye is permanently and covalently bonded to the leather via a bridging group, preferably in the region of the surface, and the bridging group is essentially bonded to the leather via —N?CH— groups.
