Coating Agent for Paper and Coated Paper Using Same
A coating agent for paper comprises: an ethylene-vinyl alcohol copolymer, wherein the ethylene-vinyl alcohol copolymer has a content of ethylene units of 1 mol % or more and less than 20 mol % and a block character of the ethylene units from 0.90 to 0.99. Coated paper is obtained by coating paper with such a coating agent. The coating agent of the present invention is excellent in viscosity stability and also causes the resulting coated paper to be excellent in barrier properties and water resistance.
GOLF BALLS HAVING LAYERS MADE OF SILICONE ELASTOMERS
Multi-layered golf balls having at least one layer made of a foamed silicone composition are provided. Multi-layered golf balls having at least one layer made of non-foamed silicone elastomer composition also are provided. For example, three-piece, four-piece, and five-piece golf balls containing different core and cover structures can be made. The foamed silicones have good thermal stability and durability without sacrificing resiliency. The non-foamed silicone elastomers have high elongation, tensile strength, chemical/fluid-resistance, and weatherability properties. These compositions can be used to form any layer, for example, core, intermediate, or cover, in the golf ball.

ETHYLENE ACID COPOLYMERS, THEIR IONOMERS, AND THEIR USE IN PACKAGING FILMS AND INJECTION MOLDED ARTICLES
Provided are novel ethylene acid copolymers, their ionomers and their use in various articles, including packaging films and injection molded articles. The ethylene acid copolymers comprise copolymerized units of ethylene, about 10 to about 30 wt % of copolymerized units of a first α,β-unsaturated carboxylic acid having 3 to 10 carbon atoms; and about 5 to about 15 wt % of copolymerized units of a derivative of a second α,β-unsaturated carboxylic acid having 3 to 10 carbon atoms. Preferred derivatives include esters, and in particular alkyl esters. These ethylene acid copolymers and ionomers have improved optical properties when compared to conventional ethylene acrylic or methacrylic acid copolymers and their ionomers.

LAMINATE
The present invention provides a laminate having an adhesive layer excellent in low-temperature adhesiveness, water resistance, and hot water resistance. The laminate includes: a substrate; and an adhesive layer laminated on at least one surface of the substrate, in which the adhesive layer is obtained by drying a coated product of an aqueous dispersion containing water and a resin (X), and the resin (X) contains two or more kinds of ethylene-unsaturated carboxylic acid copolymers (a) each having a different content of a structural unit derived from an unsaturated carboxylic acid.

GOLF BALL
In a golf ball having a core and a cover of at least one layer, the core and/or at least one layer of the cover are formed of a resin composition that includes (A) 100 parts by weight of a thermoplastic resin, and (B) 1 to 30 parts by weight of a compound having a fluorene skeleton, or a derivative thereof. This resin composition for golf balls has an improved injection-moldability and thus enables the ball to achieve both a reduced spin rate and a good durability (scuff resistance).
