In the following, "(meth)" is used in the same sense. In addition to the 2-ethylidene (mercapto) acrylate, it may be added as needed, and has at least one thiol unsaturated bond. A compound such as 2-hydroxypropyl (decyl) acrylate, polyethylene glycol mono(indenyl) adienoate, polypropylene glycol mono(indenyl) acrylate, triterpene mono(methyl) An acrylate, trimethyl bis(indenyl) acrylate, propylene alcohol, ethylene glycol propylene ether, glycerin (mono, di) propenyl ether, N-methyl (meth) enediamine, or the like a mixture of such. Furthermore, the above "(single and second)" is the performance of both the oil-and-acrylic ether and the glycerol-dipropenyl ether. This does not mean that the two are used together. It also means to use it separately. Further, it can be used for the synthesis of an aminotriazine compound containing a (meth) acrylate prepolymer in a triazine ring, which is a compound in which three carbon atoms of a triazine ring of GN3 are bonded to an amine group, respectively. The term "aminotriazine compound" means an aminotriazine itself or an aminotriazine derivative.
