  • Polyester with epoxy monomer, and a cross-linking monomer
    Patent number: 3933939
    Abstract: A liquid unsaturated resin composition for coating material which comprises (A) 60 to 95 parts by weight of liquid resin and (B) 5 to 40 parts by weight of polyvinyl monomer, having high boiling point, in which said liquid resin is produced by adding a compound having both epoxy group and polymerizable unsaturated group to a linear polyester having terminal carboxyl groups and said linear polyester is produced by condensation of (a) aromatic dibasic acid or its acid anhydride and (b) aliphatic saturated compounds consisting of saturated aliphatic dibasic acid and saturated aliphatic glycol.
