Abstract

975,456. Photosensitive vesicular materials. A. F. DAECH. March 13,1961 [March 14,1960; Feb. 10, 1961], No. 9145/61. Heading G2C. Photosensitive material comprises a reactive compound capable of being cross-linked, a blocked polyisocyanate cross-linking agent, and a photolytic compound capable of releasing gas on exposure to light, said blocked polyisocyanate being unblocked by heat so as to react with the said reactive compound to give a cross-linked thermosetting resin. The reactive compound may be the film-former itself such as a terpolymer of vinyl chloride, vinyl acetate and vinyl alcohol or other resinous polyol or polyamine, or it may be a polyfunctional compound such as N, N, N<1>, N<1>-tetrakes (2-hydroxypropyl) ethylene diamine in an inactive binder such as a vinylidene in chloride/acrylonitrile copolymer. The photolytic compound is preferably a diazo compound and the polyisocyanate may be toluene diisocyanate which may be blocked by reaction with an aliphatic alcohol such as trimethycarbinol, 2-methyl-3-butyn-2-ol or 3-methyl-1-pentyn-3-ol, or with a phenol. Alternatively, the polyisocyanate may be blocked by a dimer or trimer formation. After imagewise exposure to light whereby gas bubbles are released, the film is heated to unblock the polyisocyanate and cause formation of a cross-linked thermosetting resin.
