  • Publication number: 20190240117
    Abstract: A two-package dental adhesive composition is provided that has an excellent adhesive property for each of various dental materials and also has excellent storage stability. The two-package dental adhesive composition includes a first agent and a second agent which are divided from each other. The two-package dental adhesive composition includes at least five components including: (A) an acidic group-containing polymerizable monomer; (B) a sulfur atom-containing polymerizable monomer; (C) a silane coupling agent; (D) a borate compound; and (E) water. The first agent contains only (A) the acidic group-containing polymerizable monomer and (B) the sulfur atom-containing polymerizable monomer out of the five components. The second agent contains only (C) the silane coupling agent, (D) the borate compound, and (E) the water out of the five components.

  • Patent number: 5748238
    Abstract: A video camera with a VTR for recording/playback of images communicates with a camera/VTR station by means of an opto-electronic link. A first opto-electronic link operates when the camera is positioned away from the camera/VTR station, and a second opto-electronic link operates when the camera is positioned on the camera/VTR station. The first opto-electronic link operates when the video camera does not record.

  • Patent number: 4760150
    Abstract: A 2,4-5-triphenylimidazole compound having the formula: ##STR1## wherein each of R.sub.1 to R.sub.5 is a hydrogen atom, a C.sub.1 -C.sub.4 alkyl group, a C.sub.1 -C.sub.4 alkoxy group, a fluorine atom, a chlorine atom, a bromine atom, a trifluoromethyl group or a trichloromethyl group, and A is a group having the formula: ##STR2## wherein R.sub.1 and R.sub.5 are as defined above. These compounds are useful as chlorine sources for photographic image-forming compositions, and as intermediates for dimers of 2,4-5-triphenylimidazoles which are useful as photochromic agents in sunglasses.
