Articles comprising a substrate and a coating are described. In some examples, the coating is disposed on at least one region of the surface and comprises at least one hydrophobic layer. In some instances, the hydrophobic layer comprises a composite comprising a single metallic element or metallic compound and at least one type of surface-modified inorganic particles to provide a metal-based matrix. In certain examples, the at least one type of surface-modified inorganic particles within the metal-based matrix is embedded within the metal-based matrix and is separate from the single metallic element or metallic compound in the metal-based matrix. Processes for producing the coatings and articles are also described.

A process for producing a digital printed heat transfer, the process comprising the steps of: 1) obtaining a substrate having a release layer; 2) applying a primer suitable for electrophotographic toner to the release layer; 3) digitally-printing electrophotographic toner to define a graphic within a defined region of a substrate inclusive of both printed and unprinted areas within that region; 4) digitally printing a tacky viscoelastic binder in registration with the printed areas of the digitally-printed graphic; 5) applying a polyurethane-based powder adhesive to the defined region of said substrate; 6) removing loose powder adhesive that does not adhere to the defined regions of said graphic; and 7) fusing and bonding the adhesive to the digital printed graphic. The binder precisely secures the adhesive powder to the printed graphical areas. The result is then cooled to set the image for use as a heat transfer.

A coating apparatus includes: a container configured to accumulate a coating liquid; a rotatable coating bar arranged at an opening part so that the coating bar has a clearance between the coating bar and a downstream side end of an upstream side cover and a clearance between the coating bar and an upstream side end of a downstream side cover and a rotation axis direction of the coating bar is directed in a longitudinal direction of the container; a plurality of rotatable supports intermittently arranged along the rotation axis direction of the coating bar; and an in-liquid cover extending in the longitudinal direction of the container.

The invention is generally related to a method for producing, in a consistent manner, contact lenses each having an intact durable coating thereon, wherein the coating is a hydrogel coating formed by covalently attached a hydrophilic polymeric material having azetidinium groups onto a base coating of a polyanionic polymer on a contact lens at a relatively low temperature (e.g., from about 40° C. to about 60° C.). The coating temperature for forming a durable hydrogel coating on top of the base coating of a contact lens can be significantly lowered by raising, in situ, the pH (to about 9.5 or higher) of a reactive coating solution which contains the hydrophilic polymeric material having azetidinium groups.
