摘要:
A process for controlling curl in polyester film is disclosed in which a cost sheet is heated assymetrically across its thickness during longitudinal stretching to product positive, negative or zero curl, as required for subsequent uses or treatments of the film formed by such stretching.
摘要:
An inkjet recording element comprising a support extrusion coated with a porous hydrophilic material. The composition comprises a hydrophilic thermoplastic polymer and blends thereof. Also disclosed are methods for making and a method of printing on the inkjet recording element.
摘要:
The present invention provides an optical element having an optical film, the optical element comprising a support frame having a shaft therein, the support frame being provided around a perimeter of the optical element and the optical film having slots on a periphery thereon, the periphery of the optical film being provided on the support frame. The invention further provides a pin provided in each of the slots and protruding into the support frame and slidable on the shaft by a controlled tensile force and a spring mechanism that is slidable on the shaft for providing the controlled tensile force to the optical film, wherein the optical film is an asymmetric diffuser.
摘要:
An optical element comprises at least one optical film wherein at least a portion of the optical film is maintained dimensionally stable by the presence of a mechanism for application of a controlled tensile force via an elastic material bonded to the perimeter of the film.
摘要:
Thermal-dye-transfer labels, and pre-label media from which they are made, comprising an extruded pragmatic polymer film comprising a microvoided layer, a continuous phase of which comprises a polylactic-acid-based material wherein the microvoids are formed by employing relatively smaller size void initiators, including, for example, various inorganic particles such as titanium dioxide. A method of making sheets for such media is also disclosed involving an extrusion process. High-quality pressure-sensitive labels for application to packages are obtainable by the present invention.
摘要:
The present invention relates to a thermal image recording element comprising a microvoided layer comprising a continuous phase polyester matrix having dispersed therein crosslinked organic microbeads and non-crosslinked polymer particles that are immiscible with the polyester matrix of the microvoided layer.
摘要:
Disclosed is a coextruded film comprising a transparent polymeric inner core layer of thickness less than 250 &mgr;m and two peelable outer polymeric layers wherein the inner layer constitutes a low enough proportion, less than 40%, of the total film thickness and exhibits a low enough melt flow index value to achieve a birefringence of not more than 1×10−4 nm/nm.
摘要:
Disclosed is a thermal dye-transfer dye-image receiving element comprising: (a) a dye-receiving layer 1; (b) beneath layer 1, a microvoided layer 2 containing a continuous phase polyester matrix having dispersed therein crosslinked organic microbeads, said layer having a void volume of at least 25% by volume; and (c) beneath layer 2, a microvoided layer 3 comprised of a continuous phase polyester matrix having dispersed therein non-crosslinked polymer particles that are immiscible with the polyester matrix of layer 3. The invention provides a receiver exhibiting an improved combination of dye-transfer efficiency and tear strength.
