The invention relates to particles with an average particle size of 300 to 1000 μm, comprising a modified polyvinyl alcohol having vinyl alcohol units and structural units represented by formula (1), wherein a content of the vinyl alcohol units is 60 to 90 mol % based on the total structural units: ##STR00001## wherein R.sup.1 represents a hydrogen atom or a methyl group. Thus, the present invention provides particles containing a modified polyvinyl alcohol having high water solubility and high affinity for a photosensitive monomer, which are highly photosensitive.

A thermochromic polymeric nanocomposite includes layered double hydroxides (LDHs) and an embedded organic polymer. The thermochromic polymeric nanocomposite exhibits thermochromic activity, e.g., changes in color in response to a change in higher temperatures. The higher temperatures can range from 100° C.-150° C. or higher. As such, the thermochromic polymeric nanocomposite can be used to monitor temperature changes for materials approaching very high temperatures.
