A microfluidic device includes a substrate; at least one inorganic layer provided on the substrate; a patterned epoxy layer formed over the at least one inorganic layer, the patterned epoxy layer including a wall that defines a location for a fluid in the microfluidic device; and an alkoxysilane material containing a primary or secondary amine for promoting adhesion between the at least one inorganic layer and the patterned epoxy layer.

Microfluidic device having improved epoxy layer adhesion

A method for making a microfluidic device, the method includes providing at least one inorganic layer on a substrate; applying an alkoxysilane material containing a primary or secondary amine on the at least one inorganic layer; baking the applied alkoxysilane material at a temperature greater than 130 degrees C.; applying an epoxy material to form an epoxy layer, wherein the applied alkoxysilane material is disposed at an interface between the epoxy layer and the at least one inorganic layer; and patterning the epoxy layer to provide a wall for defining a location for a fluid in the microfluidic device.

Making a microfluidic device with improved adhesion

The present invention generally relates a method of forming a polarizing plate comprising providing two protective cover sheets, each protective cover sheet for polarizers comprising a low birefringence protective polymer film and a layer promoting adhesion to poly(vinyl alcohol)-containing films comprising a hydrophilic polymer. The cover sheets are brought into contact with a PVA dichroic polarizing film such that said layer promoting adhesion to poly(vinyl alcohol)-containing films in each of said two cover sheets is in contact with said PVA dichroic polarizing film. A glue composition is applied just before contacting said PVA dichroic polarizing film and said cover sheets, said glue composition being substantially free of dissolved polymer and comprising a crosslinking agent that crosslinks PVA.

The present invention relates to a polymer microsphere comprising at least one polymer and at least one bound latent colorant, wherein the microsphere is stabilized by at least one stabilizing polymer. The invention also includes a method of preparing polymer microspheres comprising combining latent colorant, ethylenically unsaturated monomer, stabilizing polymer, and an initiator in solvent and initiating polymerization to form a polymeric microsphere stabilized by a stabilizing polymer bound to the surface of the polymeric microsphere.

A heat-sensitive composition can be used to make a heat-sensitive imaging material. The composition includes a water-soluble or water-dispersible binder and dispersed therein, a photothermal conversion material, and hybrid particles of a combustible nitro-resin and an addition polymer derived from one or more ethylenically unsaturated polymerizable monomers. The hybrid particles preferably have a core-shell structure with the combustible nitro-resin comprising the core and the addition polymer providing the shell. These imaging materials are particularly useful as 'direct-write' thermally imageable elements useful to provide lithographic printing plates without ablation or the need for alkaline development.

Water-compatible branched or unbranched epoxy compounds comprise a backbone having covalently attached two or more epoxy moieties and one or more of the same or different sulfonate or thiosulfate moieties.

An imaging member, such as a negative-working printing plate or on-press cylinder, can be prepared using a hydrophilic imaging layer comprising a hydrophilic heat-sensitive polymer containing a crosslinking agent comprising ionic groups and epoxy groups. This polymer may comprise quaternary ammonium carboxylate groups which may include at least one substituted-alkylene(C-C)-phenyl group. The imaging member also includes an infrared radiation sensitive material to provide added sensitivity to heat that can be supplied by laser irradiation in the IR region. The heat-sensitive polymer may be 'switchable' in response to heat, and provides a lithographic image without wet processing.
