GOLF BALLS HAVING COVERS WITH DECORATIVE EFFECT COATINGS
Golf balls having covers with decorative-effect coatings are provided. The golf balls are fashionable and decorative with unique appearances. In one embodiment, a golf ball comprising a core having at least one layer and cover having at least one layer is provided. The outer cover surface can have surface textured dimples and a decorative-effect first coating can be applied to this outer surface. A transparent second coating can be applied over the decorative-effect coating. In another embodiment, a semi-transparent metallic first coating overlies the outer cover surface and a decorative-effect second coating overlies the metallic coating.
MULTI-LAYER COATING FILM AND MULTI-LAYER COATING FILM FORMATION METHOD
Provided is a multilayer coating film comprising a colored base coating film and an effect base coating film formed on the colored base coating film, wherein the hue angle h in the L*C*h color space diagram is within the range of 30° to 70°, and when the following formulas hold: X=[(C*45).sup.2+(C*75) .sup.2].sup.1/2, and Y=[(L*15).sup.2+(C*15).sup.2].sup.1/2+[(L*25).sup.2+(C*25).sup.2].sup.1/2, X is 80 or more and Y is 140 or more; provided that C*15, C*25, C*45, and C*75 represent the chroma of the multilayer coating film when light is illuminated at an angle of 45 degrees and received at angles of 15 degrees, 25 degrees, 45 degrees, and 75 degrees deviated from the specular reflection light in the incident light direction, and L*15 and L*25 similarly represent the lightness of the multilayer coating film.

EFFECT PIGMENTS COATED WITH ORGANIC BINDERS FOR POWDER PAINTS, AND A METHOD FOR PRODUCING SAID COATED EFFECT PIGMENTS AND THEIR USE
The invention relates to coated effect pigments, wherein the coating comprises a binder which is suitable for powder paints. They comprise a crystalline and an amorphous fraction which is determined by C.sup.13 NMR MAS relaxation measurements, the relaxation of the .sup.13C cores being fitted as a biexponential relaxation according to the formula (II) and the degree of crystallinity c being in a range between 40 to 85%, and relaxation having a short average relaxation time T.sub.1.sup.s and a long average relaxation time T.sub.1.sup.l, and T.sub.1.sup.l being in a range of from 65 to 130 s. The effect pigments coated according to the invention have at least one endothermic peak with a maximum from a range of T.sub.max=100 to 150° C. and an enthalpy ΔH associated with said peak from a range of 15 J/g to 80 J/g in DSC at a feed speed of 5° C./min, the enthalpy being calculated relative to the amount of the binder. The binders are applied to the effect pigment by way of spontaneous precipitation.
