PURPOSE:To obtain a coating which gives an extremely thin coating film having excellent adhesiveness, flex resistance, surface hardness, salt-water resistance, etc., and is useful as a coating applied to the inside of a can for canned goods, by using a specified diene polymer as principal component. CONSTITUTION:A liquid diene polymer (A) having terminal (meth)acryloyl groups is obtained by reacting a liquid diene polymer (a) having terminal hydroxyl groups (e.g., a liquid polybutadiene) with a reaction product (b) of (meth)acrylic acid with a polyisocyanate. A liquid diene polymer (B) having terminal carboxyl groups is obtained by reacting component (a) with an unsaturated carboxylic acid (anhydride) (c). A liquid diene polymer (C) having terminal epoxy groups is obtained by reacting component (a) with, e.g., epichlorohydrin (d). A liquid diene polymer (D) having terminal hydroxyl groups and having epoxy groups in the molecular chain is obtained by reacting component (a) with, e.g., peracetic acid (e). One or more components selected from components A-D are diluted with a diluent.
