| abstract | 1436443 Photocurable compositions MITSUBISHI RAYON CO Ltd 17 Sept 1973 [19 Sept 1972] 43553/73 Headings C3P and C3B Photocurable compositions, useful as paint or ink binders or as adhesives, comprise (A) at least one divalent or trivalent metal salt of an olefinically unsaturated mono- or di-carboxylic acid, (B) at least one polyunsaturated compound having from 0À5 to 12 polymerizable olefinic bonds per 1000 of molecular weight and (C) at least one photosensitizer, components (A) and (B) being present in amounts of 2-60% and 98-40% respectively based on the total weight of (A) and (B). The compositions can be cured in the presence of oxygen. Component (A) may be derived from an acid such as acrylic, methacrylic, crotonic, maleic, itaconic, α- methylene glutaric acid or substituted derivatives thereof; the cation may be any of Zn, Mg, Ca, Sr, Ba, Cd, Hg, Cu, Al, Fe, Co and Ni. Component (B) may be an unsaturated polyester, an unsaturated acrylic resin or, particularly, an unsaturated compound obtained by reacting (i) a polyepoxy compound with an unsaturated carboxylic acid; (ii) a product from (i) with a diisocyanate in a molar ratio of from 2 : 1 to 3 : 2 to produce a tetravinyl or hexavinyl compound; (iii) a dicarboxylic acid with glycidyl acrylate or methacrylate in a molar ratio of 1 : 2; (iv) a product from (iii) with a diisocyanate in a molar ratio of from 2 : 1 to 3 : 2 to produce a tetravinyl or hexavinyl compound; or (v) a polyol having 2-4 hydroxyl groups with an unsaturated carboxylic acid to produce a di-, tri- or tetra-vinyl compound. Suitable photosensitizers include benzoin, benzoin ethers, benzophenone, azobisisobutyronitrile and trimethylbenzylammonium chloride. The composition may optionally include other vinyl monomers, alkyd resins, fatty oils and, in paint or ink applications, may contain a dye or pigment. In Example I a polyunsaturated component (B) is prepared by esterifying 2-hydroxyethyl acrylate with phthalic anhydride in the presence of 2-dimethylaminoethyl methacrylate, and then reacting residual carboxyl groups in the product with an epoxy resin. A similar reaction is effected in Example 2 but using 2-hydroxyethyl methyl itaconate as the hydroxy-ester and diethylene glycol diglycidyl ether as the epoxy reactant. In other examples succinic anhydride, tetrahydrophthalic anhydride, itaconic anhydride or α-methylene glutaric anhydride are used instead of the phthalic anhydride in Example 1, and also diglycidyl hexahydrophthalate as an epoxy reactant. Example 6 illustrates the preparation of another poly-unsaturated compound by reacting a diepoxy compound (obtained from bisphenol A and epichlorohydrin) with acrylic acid in the presence of 2-dimethylaminoethyl methacrylate, and then reacting the product, in the presence of n-butyl acrylate, with 2,4-tolylene diisocyanate. The procedure of Example 6 is repeated using l-epoxyethyl-3,4-epoxycyclohexane as the diepoxy compound, or with hexamethylene diisocyanate as the diisocyanate reactant. |
