The disclosure provides a carrier for flexible microassay devices (510). The carrier is detachably attached to the microassay device (510) and provides means for protecting and handling the flexible microassay device (510). A method of preparing a microassay device for use is also disclosed.
摘要:
Photothermographic elements having improved post-processing stabilty are described. These elements comprise a support bearing at least one photosensitive, image-forming photothermographic-emulsion layer comprising:(a) a photosensitive silver halide;(b) a non-photosensitive, reducible silver source;(c) a reducing agent for said non-photosensitive, reducible silver source,(d) a binder; and(e) a compound capable of releasing a post-processing stabilizer having a nucleus of the formula: ##STR1## wherein: A represents any monovalent group for which the corresponding compound AH functions as a post-processing stabilizer.
摘要:
A photothermographic element containing a transparent substrate having one major surface thereof containing the following layers sequentially coated thereon: an image-receiving layer; an opacifying layer; a first dry silver layer; an interlayer containing thermoplastic polymer; a second dry silver layer; an interlayer containing thermoplastic polymer; and a third dry silver layer, wherein the first, second, and third dry silver layers each contain a light-insensitive, reducible silver source; light-sensitive silver halide, and as a reducing agent for the light-insensitive, reducible silver source, a material oxidizable to a colored dye whose color differs from that capable of being formed in each other dry silver layer, each of the dry silver layers being individually sensitized to light of different wavelengths.

The disclosure provides microstructured articles and methods useful for detecting an analyte in a sample. The articles include microwell arrays. The articles can be used with an optical system component in methods to detect or characterize an analyte
摘要:
A direct thermographic material has one or more thermographic layers comprising a film-forming polymer binder on a polymeric support. Disposed between the polymeric support and the one or more thermographic layers is a non-light sensitive adhesive layer comprising one or more polyisocyanate crosslinked hydrophobic polymer binders.
摘要:
Various photothermographic elements are provided containing a transparent substrate; image receiving layers; dry silver layers; interlayers; and a translucent or opacifying layer. The translucent or opacifying layer can occupy a variety of positions in the photothermographic element relative to the dry silver layers. The translucent or opacifying layers serve to help produce a reflection print upon exposure of the photothermographic element to actinic light and subsequent heating of the exposed element for image development and dye transfer.
摘要:
The present disclosure provides a light control film that is capable of transmitting light, or allowing a viewer to observe information, only within a viewing region centered around the normal (perpendicular line) to a surface. The light control film generally blocks information or light outside of this viewing region, and provides security in all directions including right-and-left and up-and-down of the film. The light control film includes a plurality of light-transmissive cavities that are surrounded by a light absorbing material, such that each of the plurality of cavities is optically isolated from adjacent cavities. Each of the light-transmissive cavities effectively block light which enters the cavity outside of a viewing (that is, cutoff) angle.
摘要:
A direct thermographic material has one or more thermographic layers comprising a film-forming polymer binder on a polymeric support. The binder for at least one thermographic layer comprises a hydrophobic, organic soluble binder that is a polyvinyl acetal having a degree of polymerization greater than 650 and less than 2500.
摘要:
High contrast thermographic and photothermographic materials comprise a barrier layer to prevent migration of diffusible by-products resulting from high temperature development. The barrier layer comprises a film-forming polymer(s) that reacts with or acts as a physical barrier to diffusible by-products resulting from development including formic acid, hydrazo compounds, azo compounds, diimide compounds, hydrazine, and water.
