Methods and apparatuses for roll coating are provided. The roll coating system () includes a coating roll () having a deformable inner layer () with a surface thereof covered by a deformable outer layer (), the inner layer being softer than the outer layer. A substrate () is conveyed to the nip () between the coating roll and a back-up roll (). A metered coating material is transferred from the coating roll to a patterned surface structure () of the substrate at the nip to form a conformal coating on the patterned structure of the substrate.

Roll coating using metered coating roll including deformable layers

Methods and apparatuses for applying coatings on a moving web are provided. A coating die and a back-up roll engage with each other. The back-up roll includes a shell rotatably supported by a pressurized air layer. When a coating material is dispensed from the coating die onto the web to form a liquid coating, the pressure of the air layer is controlled such that the shell translates in space to balance forces from the air layer and the coating bead, while the web is being translated to drive the shell.

A printing system () including a printing roll () is provided. The printing roll () includes an elastically deformable and compressible inner layer () and a thin outer shell () to cover the inner layer (). The thin outer shell () includes a pattern of raised print features () to receive ink material thereon. The inner layer () is softer and thicker than the thin outer shell (), and optionally, the thin outer shell () is removable from the inner layer (). The inner layer () of the printing roll () has a thickness, a compression force deflection value and an elastically-deformable compressibility such that the raised print features () of the printing roll () do not slide or deform with respect to the printed web () in an amount to generate a substantially visible dot gain.

Methods and apparatuses for applying coatings () on a moving web () are provided. A slot die () and a back-up roll () engage with each other. The back-up roll has a deformable inner layer () with a surface thereof covered by a deformable outer layer (). The slot die and the flexible web at a contacting area are impressed into the back-up roll with an engagement depth D, which enables formation of a coating having a substantially uniform thickness.

Methods and apparatuses for applying coatings on a baggy web are provided. A Mayer rod and a back-up roll engage with each other to form a nip. The back-up roll has a deformable inner layer with a surface thereof covered by a deformable outer layer. The Mayer rod and the flexible web at a contacting area are impressed into the back-up roll with a machine-direction nip width W and a nip engagement depth D, which enables formation of a coating having a substantially uniform thickness.

A process for applying a coating material onto a substrate as a non-uniform discontinuous pattern of coating material, the method including the present disclosure describes a method of applying a coating material onto a substrate, including providing a first distribution manifold having a cavity and a multiplicity of first dispensing outlets in fluid communication with the cavity, creating relative motion between a substrate and the dispensing outlets in a first direction; dispensing a first coating material from the dispensing outlets while maintaining the relative motion and translating the multiplicity of dispensing outlets in a second direction non-parallel to the first direction, and varying a rate of dispensing of the first coating material in a predetermined fashion to form a discontinuous pattern of the first coating material on a major surface of the substrate. Useful non-uniformly patterned coated articles can be prepared using the process.

A process for applying a coating material onto a substrate as a non-uniform patterned layer of coating material, the method including providing a first distribution manifold having a cavity and a first multiplicity of dispensing outlets in fluid communication with the cavity, providing a second distribution manifold having a cavity and a second multiplicity of dispensing outlets in fluid communication with the cavity, creating relative motion between a substrate and the dispensing outlets in a first direction, dispensing a first coating material from the first dispensing outlets while maintaining the relative motion and simultaneously translating the plurality of dispensing outlets in a second direction non-parallel to the first direction, and dispensing a second coating material from the second dispensing outlets while maintaining the relative motion and simultaneously translating the plurality of dispensing outlets in a second direction non-parallel to the first direction. Useful non-uniformly patterned coated articles can be prepared using the process.

A system, including a moving web of material unwound from a support and a stamp mounted on a roller, wherein the stamp includes a base surface and a continuous, regular array of pattern elements having a trapezoidal cross-sectional shape and extending above the base surface, and wherein the stamping elements each have a substantially planar stamping surface. An inking roller with an inking surface at least periodicially contacts the stamping surface of the stamping elements. The inking surface is impregnated with an ink composition including an organosulfur compound having a thiol functional group selected to bind to a major surface of the web material to form a self-assembled monolayer (SAM) thereon according to the array of pattern elements on the stamping surface.

An article including a release liner with an adhesive layer disposed thereon, the adhesive layer including a plurality of stripes of a first pressure-sensitive adhesive and of a second pressure-sensitive adhesive, arranged in a generally alternating pattern. The first pressure-sensitive adhesive is a silicone-based pressure-sensitive adhesive that includes a silicone block copolymer elastomer comprising hard segments that each comprise at least one polar moiety, and the second pressure-sensitive adhesive is an organic polymeric pressure-sensitive adhesive.

A method includes providing an elastomeric stamp including a stamping surface with a first pattern element having a fill factor of 20 to 99 percent and including a continuous region and at least one discontinuous region, the discontinuous region including at least one of: (1) one or more elongated concavities, and (2) one or more interior voids. A second pattern element of the stamping surface has a fill factor of 0.25 to 10 percent, and includes traces with a width from 0.1 micrometers to 50 micrometers. The stamping surface is inked with an ink composition including a functionalizing molecule with a functional group selected to bind to a surface of the ink-receptive material. The inked stamping surface is contacted with an ink-receptive material selected from a sheet or a web for a contact time sufficient to bind the functional group with the surface of the ink-receptive material to form a self-assembled monolayer (SAM) of the functionalizing material.
