摘要:
Naphthacene-5,12-diones which are substituted by at least one organic thio radical are not only photoinitiators for the photopolymerization but also sensitizers for the photodimerization of ethylenically unsaturated compounds. Compositions made of these naphthacene-5,12-diones and ethylenically unsaturated compounds are suitable for the preparation of printing inks, paints, printing plates, resist materials or as image recording material.

摘要:
Benzocyclobutene-1,2-dichlorides, -bromides and -iodides which are substituted in the benzene ring are accessible in good yields and short reaction times by reacting substituted 1,2-(dichloromethyl or dibromomethyl)-benzenes with NaI in acetonitrile as the solvent. They can be used together with dienophils, for example 1,4-quinones, in Diels-Alder reactions.
摘要:
The imidyl compounds, according to the invention, of the formula I are suitable for the manufacture of polymers which can be crosslinked by light, which polymers can be, for example, polyesters, polyamides, polyamide-imides, polyimides, polyester-polyamides, polyester-amide-imides, polyethers, polyamines, polysaccharides and polysiloxanes. Polymers of this type are suitable for carrying out photochemical processes. Compared with known polymers, the polymers based on the imidyl compounds according to the invention have the advantage that they are photochemically substantially more sensitive. In addition, this sensitivity can also be further increased effectively by a combination with sensitizers.
