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:
A single or multilayer sheet comprising a microvoided layer permeable to low surface tension liquids has a continuous phase comprising a polylactic-acid-based material and interconnecting microvoids, said microvoided layer having a total absorbent capacity of at least about 14 cc/m2. The invention is also directed to an a method of making a sheet material comprising such a permeable microvoided layer, which method comprises extruding a sheet comprising a layer of a polylactic-acid-based material containing inorganic particles by extrusion, and stretching the sheet biaxially to form interconnected microvoids around the inorganic particles.
摘要:
The present invention relates to an inkjet recording element having good dye keeping properties in time and good image quality. Said inkjet recording element comprises a porous polyester support and at least one ink-receiving layer, said ink-receiving layer comprising at least one hydrosoluble binder and at least one aluminosilicate polymer obtainable by a preparation method consisting in treating an aluminum halide with an alkyl orthosilicate only having hydrolyzable functions with an aqueous alkali in the presence of silanol groups, the aluminum concentration being maintained less than 0.3 mol/l, the Al/Si molar ratio being maintained between 1 and 3.6 and the alkali/Al molar ratio being maintained between 2.3 and 3; and then stirring the resulting mixture at ambient temperature in the presence of silanol groups for long enough to form the aluminosilicate polymer.
