Patent ID: 8507100

Claim:
A resin primer containing a resin, wherein said resin contains a polyamideimide, and the polyamideimide has a structural unit of a saturated hydrocarbon, wherein the resin primer further contains a rubber ingredient, the rubber ingredient being different from the polyamideimide, and being selected from the group consisting of acrylic rubber, natural rubber, isoprene rubber, butadiene rubber, chloroprene rubber, nitrile rubber, and urethane rubber, wherein said rubber ingredient content is 40 mass % or more based on the mass of said resin, and wherein said polyamideimide is obtained by the reaction of a diimide-dicarboxylic acid, obtained by reacting a diamine compound and anhydrous trimellitic acid, with a diisocyanate, the diamine compound being expressed by the following general formulae (6a), (6b) or (6c): [in the formulae, R 61 is a hydrogen atom, or a hydroxyl, methoxy, methyl or halogenated methyl group, R 62 is one of the groups expressed by the following general formulae (7a), (7b), (7c) or (7d), an alkylene group having 1-3 carbon atoms, a halogenated alkylene group having 1-3 carbon atoms, a sulfonyl group, an ether group, a carbonyl group or a single bond, and R 63 is an alkylene group having 1-3 carbon atoms, a halogenated alkylene group having 1-3 carbon atoms, a sulfonyl group, an ether group or a carbonyl group: where, in formula (7a), R 7 is an alkylene group having 1-3 carbon atoms, a halogenated alkylene group having 1-3 carbon atoms, a sulfonyl group, an ether group, a carbonyl group or a single bond; and the plural R 61 s may be respectively identical or different].
