  antiparallel forms of cis‐ and trans‐1,2‐dicyano‐1,2‐bis(2,4,5‐trimethyl‐3‐thienyl)ethene was studied by NMR spectroscopy. Photocyclisation or cis/trans isomerisation was induced by irradiation with 405 or 365 nm light. Extended irradiation of the cis compound generated two peroxy derivatives that thermally convert into a new coloured compound with its own photochromic properties.

  通过NMR光谱研究了顺式和反式1,2-二氰基-1,2-双（2,4,5-三甲基-3-噻吩基）乙烯的平行和反平行形式之间的平衡。通过用405或365nm的光照射诱导光环化或顺式/反式异构化。顺式化合物的延长照射产生了两种过氧衍生物，它们被热转化为具有自身光致变色特性的新的有色化合物。

  An organic compound having an affinity for a resin of a molded resin article and sublimation properties is allowed to penetrate/disperse into the surface of the molded resin article, thereby modifying and/or coloring a resin surface layer. The molded resin article and the organic compound having the affinity for the resin and the sublimation properties are put into a tightly closable container, and the pressure and the temperature in the container are adjusted to place them in a saturated sublimation pressure state of the organic compound, whereby a vapor of the organic compound is uniformly deposited on the surface of the molded resin article and it further penetrates/disperses into the resin surface layer, and in consequence, the resin surface layer can be modified and/or colored. In addition, the modification of the resin surface layer permits imparting a function thereto.

  A toy comprises a toy element comprising a photochromic layer which contains a photochromic compound having a photo memory function (color-memorizing photochromic property), maintains a coloring state by developing a color through the irradiation of ultraviolet rays or sunlight containing ultraviolet rays and changes into decolorizing state through its decolorization by the irradiation of visible light, and a color-changing means which contains at least one of an ultraviolet ray absorbent and a light-shading pigment capable of shading at least ultraviolet rays, changes the photochromic compound of the coloring state into decolorizing state by cutting off ultraviolet rays of sunlight and thereby effecting irradiation of visible light, and maintains the changed state, wherein a function to memorize and maintain coloring and decolorizing states alternately is expressed by arranging the color-changing means under such a condition that it is covering or not covering the photochromic layer.
