| abstract | 1291107 Coating compositions; polymer preparations and modifications MITSUBISHI RAYON CO Ltd 19 Dec 1969 [23 Dec 1968] 62161/69 Headings C3G and C3P Coating compositions, which give coatings curable with radiation (e.g. electron beam or UV radiation), comprise a solution in a solvent of a polymer of (1) a base copolymer having an average molecular weight of 1000 to 100,000 and comprising (A) units of at least one vinyl monomer having a hydroxyl group and (B) units of at least cne α,#-ethylenically unsaturated carboxylic acid ester of a C 1 -C 18 monohydric alcohol; said base copolymer having been reacted with (2) at least one polybasic carboxylic acid anhydride to esterify at least 10% of the hydroxyl groups of the base copolymer and then with (3) at least one epoxy vinyl monomer to esterify and/or etherify at least 10% of the total hydroxyl and carboxyl groups of the esterified base copolymer. The base copolymer may also contain units of one or more other monomers. The anhydride (2) may be saturated or unsaturated and the epoxy monomer (3) may be, for example, glycidyl acrylate or methacrylate, allyl or methallyl glycidyl ether, or vinylcyclohexene monoxide. The solvent may comprise inert and/or polymerizable compounds. In examples the base copolymer is prepared by copolymerizing (a) 2-hydroxyethyl methacrylate, methyl methacrylate, styrene and n-butyl acrylate, (b) methyl 2-hydroxyethyl maleate, methylmethacrylate, styrene and n-butyl acrylate, (c) methyl 2-hydroxyethyl itaconate, methyl methacrylate and n-butyl methacrylate, (d) 2-hydroxyethyl acrylate, styrene, methyl methacrylate and 2-ethylhexyl methacrylate, (e) 2 - hydroxypropyl methacrylate, methyl methacrylate, n-butyl methacrylate and dimethylaminoethyl methacrylate, and (f) 2- hydroxyethyl methacrylate, methyl methacrylate, monomethyl itaconate and methacrylonitrile in methanol in the presence of t- or ndodecyl mercaptan using azobisisobutyronitrile or benzoyl peroxide as initiator. Polymerizable solvents include (meth)acrylates, styrene compounds, methacrylic acid, 2-methyl-5-vinylpyridine and polyunsaturated compounds obtained by condensation of components used in obtaining the modified base copolymer. When the compositions are cured with actinic radiation a photoinitiator may be used, e.g. an azo, thiuram, peroxide or carbonyl compound, particularly benzoin, benzoin methyl ether or anthraquinone. The compositions may also include dyestuffs, pigments or metallic powders. In Example 21 an unsaturated alkyd resin is included in one of the coating compositions. |
