PURPOSE: To provide a photo-hardenable composition which is exposed to visible rays by containing a compound which is possible to be radical-addition- polymerized or to be crosslinked and an ionic dye-reactive counter ionic compound which reacts as a photo initiator. n CONSTITUTION: A photo-hardenable resin compound is provided from (A) a compound which is possible to radical-addition-polymerized or to be crosslinked and (B) a compound which contains an ionic dye-reactive counter ionic compound which can absorb chemical rays, and which can produce a radical initiating a radical polymerization or crosslinking of the component A which is possible to be radical-addition-polymerized or to be crosslinked, and also of which an ionic dye is composed of a methine dye, polymethine dye, a triarylmethane dye, indoline dye, thiazine dye, xanthene dye or the like. For example, a composition for a dental use can be provided, which contains a photo-polymerizable adhesive material with the base of acrylate as the component A and a photo- initiator of the component B. n COPYRIGHT: (C)1990,JPO |
