Abstract: One embodiment of an optical medium includes a substrate having a paper layer, an image deposited or otherwise disposed at the paper layer, a primer layer deposited or otherwise disposed at the image layer, and a receptive coating deposited or otherwise disposed at the primer layer of the substrate. One embodiment of an inkjet receptive coating or laser printable coating includes a binder (e.g., an acrylic resin) having a polyvinyl alcohol resin and a polyvinyl pyrrolidone resin incorporated therein. One manner of incorporating the resins into the binder is by blending the resins into the binder.

Abstract: The invention provides a two-part polyurethane coating suitable, for example, for coating a golf ball. The first part comprises a A) water-reducible polyol and the second part comprises B) a water dispersible, aliphatic polyisocyanate. The NCO/OH ratio of B):A) is between about 1.5:1 to about 2.5:1. The two-part composition also includes C) an organic solvent component at between about 5 and about 50 parts per hundred by weight based on total weight of A) plus B). At least about 50 wt %, up to 100% of the solvent C) comprises ethyl 3-ethoxy propionate.
