Abstract
The invention comprises compounds of the formula <FORM:0887902/IV (b)/1> and their derivatives having in the 4, 5, 6, 7, 51, 61, 71 and/or 81 positions substituents selected from CH3, CH2CH3, CH(CH3)2, C(CH3)3, C6H5, CF3, CN, COCH3, CO2C2H5, CO2H, NH2, NHCH3, N(CH3)2, N(CH3)3+, NHCOCH3, NO2, PO3H-, OCH3, OC2H5, OCH2CH2CH3, OC6H5, OCOCH3, SCH3, SH, SCOCH3, SCN, SOCH3 (methyl sulphinyl), SO2CH3 (methyl sulphonyl), SO2NH2, S(CH3)2+, F, Cl, Br, I, IO2, CH2CH=CH2 and CO2CH3; these substituents are to be sterically compatible as defined below. These compounds are colourless in solution, but on irradiation with blue to ultra-violet light the 21-11 bond is broken and the compounds are coloured; irradiation with green to infra-red radiation reverses the process. "Sterically compatible" substituents are those which do not hinder the breaking of the 21-11 bond on irradiation. The compounds in solution can be used to sensitize record materials for the recording and erasing of data by the appropriate radiation. The compounds are prepared by condensing a suitably substituted salicylaldehyde with a suitably substituted 2-ethyl-3-alkylbenzthiazole; the latter may be obtained by alkylation with an alkyl p-toluenesulphonate. An example prepares 3,31 - dimethyl - 61 - nitro - spiro - (benzothiazole - 2,21-[21H,11-benzopyran]).
