Zusammenfassung: | 1,259,761. Photo-sensitive materials. J. S. BOKOV, N. V. VIKULINA, B. A. DOGADKIN, B. V. EROFEEV, A. V. LARINA, P. LAVRISCHEV, V. MARKOV, G. D. YAROVAYA, S. F. NAUMOVA and O. D. JURINA. Jan. 8, 1970, No. 907/70. Heading G2C. [Also in Division B6] Light-sensitive materials comprise a bisazide and a polymer of cyclohexdiene-1, 3 or a copolymer thereof with a diene such as butadiene or 2- methylbutadiene. The material may be coated on a copper of silicon support, imagewise exposed and developed to produce an etching resist or a printed circuit. |
