    • The invention relates to spiropyran compounds. They have the general formula (I): ##STR1## in which: X represents the CH.sub.2 group or a sulfur atom; R.sub.1 and R.sub.2 represent electron donor and/or acceptor groups selected for instance from the group NO.sub.2, COC.sub.6 H.sub.5, CN, the halogens, the acyl substituents, alkoxy substituents, the hydrogen atom, the alkyl and mercaptoalkyl groups, the ethers of the formula CH.sub.2 OR, thioethers of the formula CH.sub.2 SR and amines of the formula CH.sub.2 NR.sub.2 in which R represents an alkyl group; R.sub.3 is a linear or branched alkyl group, having 1 to 18 carbon atoms, or an arylalkyl or alkenyl group.--R.sub.4,R.sub.5,R.sub.6,R.sub.7,R.sub.8 and R.sub.9 have one of the meanings indicated for R.sub.3 or represent, two by two, with the group in ortho position, a --(CH.sub.2).sub.n -- group in which n is a number between 5 and 10.R.sub.10 represents a hydrogen atom if X=S and if X=CH.sub.2 a hydrogen atom, an alkyl group having 1 to 18 carbon atoms, an arylalkyl group in which the alkyl group has 1 to 5 carbon atoms, or an alkenyl group having 2 to 10 carbon atoms.The compounds in accordance with the invention have photochromic properties and are suitable for the recording of information on transparent or opaque supports.
    • 本发明涉及螺吡喃化合物。 它们具有通式(I):其中:X表示CH 2基或硫原子; R 1和R 2表示选自例如NO 2,COC 6 H 5,CN,卤素,酰基取代基,烷氧基取代基,氢原子,烷基和巯基烷基的基团的受体和/或受体基团,式CH2OR的醚, 式CH2SR的硫醚和式CH2NR2的胺,其中R表示烷基; R3是具有1至18个碳原子的直链或支链烷基,或芳基烷基或烯基。 -R4,R5,R6,R7,R8和R9具有R3表示的含义之一,或与邻位相同的二 - 二,a - (CH2)n-基,其中n为5 如果X = S,则R 10表示氢原子,如果X = CH 2,氢原子,碳原子数1〜18的烷基,烷基含有1〜5个碳原子的芳基烷基,或烯基 具有2至10个碳原子。 根据本发明的化合物具有光致变色性质,并且适用于在透明或不透明的载体上记录信息。
