    摘要： An reimageable medium composed of: a substrate; and a photochromic material, wherein the medium is capable of exhibiting a color contrast and an absence of the color contrast, wherein the medium has a characteristic that when the medium exhibits the absence of the color contrast and is then exposed to an imaging light corresponding to a predetermined image to result in an exposed region and a non-exposed region, the color contrast is present between the exposed region and the non-exposed region to form a temporary image corresponding to the predetermined image that is visible for a visible time, wherein the medium has a characteristic that when the temporary image is exposed to an indoor ambient condition for an image erasing time, the color contrast changes to the absence of the color contrast to erase the temporary image in all of the following: (i) when the indoor ambient condition includes darkness at ambient temperature, (ii) when the indoor ambient condition includes indoor ambient light at ambient temperature, and (iii) when the indoor ambient condition includes both the darkness at ambient temperature and the indoor ambient light at ambient temperature, and wherein the medium is capable of undergoing multiple cycles of temporary image formation and temporary image erasure.

    摘要： A method of coating a liquid or solid particulate core involves dropping or suspending the particulate core in an atmosphere and then applying a liquid coating while the particulate core is dropped or suspended, the applying of the liquid coating being done by either (a) spraying the liquid coating onto the particulate core with an ink jet or (b) moving the particulate core through a fog of the liquid coating. In a further embodiment, the method can be used for encapsulating a liquid or solid particulate core within a polymeric shell by dropping or suspending the particulate core in an atmosphere, then applying by one of the above-mentioned methods a first coating composition containing a first reactant to the particulate core while the particulate core is being dropped or suspended, and subsequently exposing the particulate core coated with the first coating composition to a second composition containing a second reactant which reacts with the first reactant, which second composition is immiscible with the first coating composition, whereby the polymeric shell is formed by interfacial polymerization. By these methods, the formation of membranes or polymer shells around a variety of particulate core materials can be done using precise amounts of coating materials, thereby reducing waste and improving efficiencies of the process.

    摘要： Disclosed is a display comprising an arrangement of a plurality of optically anisotropic rotatable elements, each of the rotatable elements having a surface in contact with an enabling fluid, the rotatable elements being electrically dipolar in the presence of the enabling fluid and thus being subject to rotation upon application of an electric field, the rotatable elements being free to rotate in place but not free to translate substantially so as to disrupt the arrangement of rotatable elements, wherein a first portion of the surface contains a mixture of a chelating agent and a spiropyran material of the formula
    or
    wherein n is an integer representing the number of repeat -CH 2 - units and R is -H or -CH=CH 2 , and wherein a second portion of the surface contains substantially no spiropyran.
