    摘要: The invention provides an ink jet recording sheet which is highly resistant to printings smearing, running, feathering, color bleeding, or fading when wet, humid, or exposed to intense or continual light. The recording sheet has a solid substrate and a composition coating the solid substrate. The composition comprises a cationic polymer as well as starch, inorganic salt, pigment, and water. The composition can further comprise a non-ionic polymer. The coating tightly binds both pigment based inkjet inks and dye based inkjet inks. The composition is easy to apply and the ink jet recording sheet can be easily formed with a standard size press device.

    摘要: The invention disclosed provides a method for inducing nucleation in a polymer by subjecting the polymer containing dissolved gas to an external stress generated, for example, by applying hydrostatic or mechanical pressure. The applied stress restricts the bubble growth so that the foamed materials have small cells and high cell density. Such microcellular foams can be produced over a wide low temperature range, i.e. from the temperature at which the polymer is conditioned with the blowing agent up to about the glass transition temperature of the polymer-blowing agent system. Stress induced nucleation can also be conducted at higher temperatures i.e. up to about the T.sub.g of the neat polymer, leading to foams with larger cells. A variety of homogeneous and heterogeneous foams can be produced by this technique.
