    摘要: The invention relates to novel radiation-sensitive compounds which are esters or amides of a 1,2-naphthoquinone-(2)-diazide-4-sulfonic acid of the general formula ##STR1## in which R.sub.1 and R.sub.2 are identical or different and denote hydrogen, an alkyl group, an alkyl ether group or an alkyl thioether group whose carbon chains may be interrupted by ether oxygen atoms, an acylamino group, carboxylic acid ester group, sulfonic acid ester group or sulfonamide group,R.sub.1 and R.sub.2 not being hydrogen at the same time.The compounds are used as radiation-sensitive components in radiation-sensitive mixtures with which corresponding copying materials can be produced. The compounds have an absorption which is directed towards longer wavelengths matching the emission range of commercially available radiation sources. They also make it possible, in a reliable and practical manner, to carry out negativeworking image reversal processes.

    摘要: The invention relates to a process for the preparation of vinylphosphonic dichloride, in which a 2-chloroethanephosphonate of the formula ##STR1## or a mixture of the two esters, is reacted with thionyl chloride at a temperature of 60.degree. to 160.degree. C. in the presence of a catalyst which contains tertiary phosphines, quaternary ammonium or phosphonium salts or alkali metal or alkaline-earth metal halides.During this reaction, any thionyl chloride which may be present is removed by distillation subsequent to this reaction, the mixture remaining is heated to 140.degree. to 200.degree. C., and the vinylphosphonic dichloride produced during this is removed by distillation.

    摘要: The invention relates to a process for the preparation of vinylphosphonic dichloride through elimination of hydrogen chloride from 2-chloroethanephosphonic dichloride in the presence of catalysts. The catalysts used are tertiary phosphines, quaternary ammonium or phosphonium salts or alkali metal or alkaline-earth metal halides. When triphenyl phosphine is used as the catalyst, the reaction is carried out under reduced pressure at a temperature of 130.degree. to 166.degree. C. and the vinylphosphonic dichloride produced is simultaneously removed by distillation under reduced pressure. When the other catalysts are used, the process can be carried out at atmospheric pressure or reduced pressure and at temperatures of about 130.degree. to 220.degree. C. and the vinylphosphonic dichloride produced can be removed by distillation simultaneously with or subsequent to the reaction.
