10-50 parts by weight of polyester resin, 0.1-30 parts by weight of amino resin, 0.1-30 parts by weight of epoxy resin, 0.1-30 parts by weight of pigment, 0.1-7 parts by weight of antisettling agent and smoothing agent, 0.1-hardening catalyst The coating composition for back surface of the coated steel plate which consists of 2 weight part, 0.1-10 weight part of polyols, and 10-50 weight part of organic solvents is disclosed. The composition of the present invention is very industrially useful because of its excellent styropol and polyethylene sheet adhesion, processability, solvent resistance and hardness at the back of the coated steel sheet at a wide range of temperatures. |
